This is my personal blog devoted to the development of 3D-Coat. This blog is created to give fast and non-official information about 3D-Coat. I will post there daily news, what I am doing now, what features are under development this moment. It could be really interesting for everyone who is interested in 3D-Coat.Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.comBlogger35125tag:blogger.com,1999:blog-4587608169864457694.post-61690868285911449972008-10-27T09:01:00.001+02:002008-10-27T09:15:31.761+02:00Volumetric sculpting progress<p>Some news on volumetric progress. Many improvements was made since previous post in this blog. One of the most improvements is incremental render. It allows render only changed parts of object. In so way there is almost no difference how big object is edited - only navigation speed is different. Now it is possible to create objects up to 18M of triangles. Also voxel sculpting has got nice renderer - with DOF, AO and soft shadows. There are some rendered samples with AO and soft shadows:</p> <p>Images made by TOXE:</p> <p><img height="493" src="http://3dbrush.kriska.hvosting.net/forum/index.php?act=attach&type=post&id=1315" width="602" /> </p> <p> <img height="488" src="http://3dbrush.kriska.hvosting.net/forum/index.php?act=attach&type=post&id=1318" width="601" /> </p> <p>Aloso there are so much great images!

Many sales, many support questions, many work over volumetric sculpting. Really multithread working :) But all is going very well. It seems 3D-Coat becomes popular cake :) Please join very hot discussion in forum about first alpha and principles of volumetric sculpting. You have a chance to make this tool better and perfect.

I am getting many letters and sales everyday. It seems that 3D-Coat is tooken seriously into account as serious competitor. It is great. Especially many peoples like retopology tool and upcoming volumetric sculpting. I have already made core for this but I need some time to bring it to some usability level.Anyway I will show very basic demo soon. From the example of developing retopology tool I see that open development is best way to make something really exciting. I need to spend several more days on making sevice updates and then I will run into 3.0 development with full power. Now I am spending only 20% of time for it.Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com1tag:blogger.com,1999:blog-4587608169864457694.post-85739857206021548372008-08-18T16:31:00.002+03:002008-08-18T16:36:31.278+03:002.10 development runs to the end.

The main new feature is retopo tool in 3D-Coat. It is really big piece of work and now it is close to final. Also Mac version is close to first beta version. There is some roadmap:<br /><br />Beta 1 discussion (maybe biggest discussion at all)<br />http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1140<br /><br />Beta 2 discussion:<br />http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1183<br /><br />MacOS announcements and news:<br />http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=948<br /><br />I have told that first MacOS beta will be released 9 of july, but I am not sure that it will be ready until this date, it is possible that it will be postponed on a week.<br /><br />Also, development 0f 3.0 will be started after releasing 2.10. I plan to release 3.0 approximately in september. The major feature is volumetric sculpting.

It is very important step to make 3DC cross plaform. I hope it will be released for macOS in a month and for Linux in two months. Other benefit of new engine - easy making diggerent handlers. I have inserted them into sculpt tool, it works very cool now! Look at screenshots:<br /><a href="http://www.3d-brush.com/pics/mrs.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 600px;" src="http://www.3d-brush.com/pics/mrs.png" border="0" alt="" /></a><br />Also you will me able to move/rotate/scale the whole closed poly areas using handlers. Sculpt tool was improved much, now symmetry worksmuch better in select and move mode. It allows you to pose object better.<br /><br />I have started retopo tool. I think it is important not only because of retopo tool itself but also like improvement to sculpt mode - you will get possibility to sculpt something essential from sphere using pair sculpt/retopo. Another application - making clothes.Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com1tag:blogger.com,1999:blog-4587608169864457694.post-4725634505178314292008-05-29T16:15:00.002+03:002008-05-29T16:18:16.465+03:00Development progressLast week I was working over making 3D-Coat cross-platform. My friend Sergey Krizhanovsky has made cross platfirm engine and last week I was busy by replacing old graphical engine with new one. It was very hard work, only 5 days was spent to compile and link program with new engine. New engine will give improved speed, OpenGL/DirectX render, very nice handlerd like in Maya. I hope to finish my part of work this week. Then Sergey should make some final changes in 3D-Coat to make it cross platorm. It is possible that Mac version will be done until the end of june (official deadline - 9 of july). So, from next week I will continue to improve functionality. At first, I plan to make retopo tool. Also, I can't wait to start volumetric tools. I was impressed by recent post of <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1097">Frankie</a> It seems to be more impressive then hard to do feature.

With this engine 3DC will support OpenGL/DirectX render and will be cross-platform. It will be big step to make 3DC compartible with MacOS. I hope we will make all in term that I have told in our forum.Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com0tag:blogger.com,1999:blog-4587608169864457694.post-25005091260789635322008-05-16T19:01:00.000+03:002008-05-16T19:02:15.586+03:003D-Coat 2.09!3D-Coat 2.09 released!

It allows to create plugins for export/import of different 3D-files. To start you should download and unpack </p> <p><a href="http://www.3d-coat.com/files/3D-CoatSDK.rar" target="_blank">http://www.3d-coat.com/files/3D-CoatSDK.rar</a></p> <p>Then you shoud open soluton ExportImport.sln. It requires at least MS VisualStudio 2008 Standart Edition to be properly compiled. Compile project. It is better to use “Release” configuration. You will get Odj.DLL file on output. This simple plugin is a sample for importing OBJ files. Obj.DLL should be copied to </p> <p><strong>$3D-CoatInstallationFolder\Plugins\MeshCodecs\</strong></p> <p>To understand how plugins work open files cMeshObj.h. You will see there class that is derived from cMeshCodec (It is defined in cIO.h). </p> <p><strong>class cMeshCodec {</strong></p> <p><strong>public:</strong></p> <p><strong>cMeshCodec() {}</strong></p> <p><strong>       virtual ~cMeshCodec() {}</strong></p> <p><strong>       virtual cRawMesh * Decode(const cData &Fm) = 0;</strong></p> <p><strong>       virtual void Encode(const cRawMesh &Mesh, cData *To) = 0;</strong></p> <p><strong>       virtual bool CanEncode(){return true;}</strong></p> <p><strong>       virtual bool CanDecode(){return true;}</strong></p> <p><strong>};</strong></p> <p>To create new codec you should derive your class from cMeshCodec and re-define functions Encode and Decode. Decode should return filled object cRawMesh and Encode should fill Data structure cData using cRawMesh. You can look and discover objects cData and cRawMesh. After redefining functions you should change class name in ExportImport.cpp. I think it is very easy. The only not so easy task is filling/reading structure cRawMesh. It is mesh that consists of:</p> <p><strong>uv-sets</strong> (see GetUVSets() )</p> <p><strong>Matrials(surfaces)</strong> (see GetMaterials() )</p> <p><strong>Objects</strong> (see GetObjects() )</p> <p><strong>PositionVertices</strong> (see GetPositions() )</p> <p><strong>UV-vertices</strong> (see GetTexCoords() )</p> <p><strong>Normals </strong>(see GetNormals() )</p> <p><strong>Faces</strong> (see GetRaw() )</p> <p>To understand how it works it is better to discover how cMeshObj.cpp encodes/decodes obj – files. I will explain slightly how Faces list is organised.</p> <p><strong>Faces</strong> are array of cVec3i – 3 integer values</p> <p><strong>Count</strong>, - amount of polygones in face </p> <p><strong>idMtl</strong> = MaterialIndex + (UV-set index<<16) – index of material and uv-set</p> <p><strong>idObj</strong> - index of object</p> <p>Next “Count” values are 3-indices of vertices that are part of face</p> <p><strong>PositionIndex</strong> (index in array of position vertices)</p> <p><strong>TexturevertexIndex</strong> (index in array of texture vertices, can be -1)</p> <p><strong>NormalIndex</strong> (index in array of normals, can be -1)</p> <p>The best method to learn is to ask in <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1058">forum</a> and discover how cMeshObj is done.</p> Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com0tag:blogger.com,1999:blog-4587608169864457694.post-8303021366131527072008-05-08T16:22:00.001+03:002008-05-08T16:22:32.323+03:00Translating to many languages<p>I have interesting idea about translating 3D-Coat to very many languages. I know that many peoples want to help to translate 3DC to native language but it seems too difficult because </p> <p>1) Too many texts for one man</p> <p>2) It is not so easy to find where texts are stored</p> <p>2) There is some xml-file - it is not convenuent to translate</p> <p>Also, using translation agencies is not effective because they usually don't know CG terminology well.</p> <p>So we started new web project - you will be able to help to translate even if you have 5 free minutes! There will be web page where you can get string that is not still translated and translate it on native language. There will be small screenshot where this string is used and text. You will be able to type the translated text. </p> Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com2tag:blogger.com,1999:blog-4587608169864457694.post-12487777956657703192008-05-08T11:41:00.001+03:002008-05-08T11:41:48.947+03:00Vector displacement<p>Now I am making support of export/import of vector displacement. What is vector displacement? You have subdivided mesh and texture for displacement. It is not grey, every channel represents shift in space in corresponding direction (XYZ). Vector displacement is important for sculpting because it allowd to displace sphere into something non-trivial like face. Using vector displacement will make export for render engines much mere easy and precise. There is two types of vector displacement</p> <p>1) World space vector displacement - RGB in picture mean XYZ shift in space. It is most precise method, but it is not good for animation.</p> <p>2) Tangent space (local space) displacement - RGB mean shift in TBN - space, N- normal, T,B - directions of U,V gradient. This kind of displacement is good for animation but less precise because tangent space calculation can be made using many methods, it even can be non - orthonormal. </p> <p>I have almost done this stuff, but I have a problem with method of calculation of tangent space in LW or Modo. If someone knows how to do that in Modo/LW, please send me the info.</p> <p>You can download and test this feature by the link</p> <p><a href="http://www.3d-coat.com/files/3d-Coat-209B3B-en.exe" target="_blank">http://www.3d-coat.com/files/3d-Coat-209B3B-en.exe</a></a> </p> <p>I have created the new topic in forum</p> <p><a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1038">http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=1038</a></p> <p>Please help in testing vector displacement.</p> <p>Also, if you have examples of EXR files with vector displacement to transform sphere of some other simple surface into something non-trivial, please send me to support. It will be great help.</p> Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com0tag:blogger.com,1999:blog-4587608169864457694.post-40851881873325065762008-05-03T20:32:00.002+03:002008-05-04T10:07:44.227+03:002.09 is coming soon!<p>3D-Coat 2.09 is almost done. There will be many new features. It will be essentially useful for LW users. The approximalte list of upcoming features:</p><p>1) Merging new objects is possible now! You can add new sub objects like eyes on your WIP.<br />2) Different uv-sets are placed on different textures, it allows you to use display memory more efficiently and get better quality.<br />3) You can choose resolution of every uv-set during import and change it any time. Also, you can change resolution of mesh separately for every uv-set. </p><p align="center"><a href="http://lh3.ggpht.com/AndrewShpagin/SByho2T_V2I/AAAAAAAAAHk/EgKpyexw2dk/ChangeResolution%5B5%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="244" alt="ChangeResolution" src="http://lh6.ggpht.com/AndrewShpagin/SByhpmT_V3I/AAAAAAAAAHs/_x4wmxRnC9M/ChangeResolution_thumb%5B3%5D.jpg" width="424" border="0" /></a></p><p><br />4) Now you can group several materials (surfaces) into single uv-set </p><p align="center"><a href="http://lh4.ggpht.com/AndrewShpagin/SByhqGT_V4I/AAAAAAAAAH0/z98rLVxtAdA/UVSetsManager%5B5%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="439" alt="UVSetsManager" src="http://lh5.ggpht.com/AndrewShpagin/SByhrWT_V5I/AAAAAAAAAH8/_UFL7YVj-yY/UVSetsManager_thumb%5B3%5D.jpg" width="421" border="0" /></a></p><p><br />5) Select and move now supports symmetry.<br />6) Gradient select in sculpt mode works better with symmetry and works much better now.<br />7) Image picker has got navigation controls to scale/move/fit image<br /></p><p align="center"><img src="http://www.3d-brush.com/pics/PickerNavi.jpg" border="0" /></p><p><br />8) Wacom pen has got better support: opacity jitter is add for pen and every jitter can depend on pressure if you want.<br /></p><p align="center"><a href="http://lh3.ggpht.com/AndrewShpagin/SByhr2T_V6I/AAAAAAAAAIE/ug9pqCrI5fo/PressureDependence%5B3%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="365" alt="PressureDependence" src="http://lh5.ggpht.com/AndrewShpagin/SByhsWT_V7I/AAAAAAAAAIM/N7xKcRUfQsQ/PressureDependence_thumb%5B1%5D.jpg" width="424" border="0" /></a></p><p><br />9) All textures (color/normals/specular) and all uv-sets could be viewed in single window <br />10) New option in fill tool using gradient - filling with opacity fading<br /></p><p align="center"><a href="http://lh4.ggpht.com/AndrewShpagin/SByhtGT_V8I/AAAAAAAAAIU/CDYz0Dr0IFo/GradientFillingTypes%5B3%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="368" alt="GradientFillingTypes" src="http://lh6.ggpht.com/AndrewShpagin/SByhtmT_V9I/AAAAAAAAAIc/CKHeSWEJ8JQ/GradientFillingTypes_thumb%5B1%5D.jpg" width="420" border="0" /></a></p><p><br />11) ... and filling with spherical gradient<br /></p><p align="center"><a href="http://lh5.ggpht.com/AndrewShpagin/SByhuWT_V-I/AAAAAAAAAIk/u58CImaQ1pY/SphericalGradientFilling%5B4%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="370" alt="SphericalGradientFilling" src="http://lh3.ggpht.com/AndrewShpagin/SByhu2T_V_I/AAAAAAAAAIs/EIlzAevBFwg/SphericalGradientFilling_thumb%5B2%5D.jpg" width="421" border="0" /></a></p><p><br />12) New menu item - View->Browse to understand the structure of 3DC folders better<br /></p><p align="center"><a href="http://lh5.ggpht.com/AndrewShpagin/SByhvWT_WAI/AAAAAAAAAI0/42cw1lw2IP0/Browse%5B3%5D.jpg"><img style="BORDER-RIGHT: 0px; BORDER-TOP: 0px; BORDER-LEFT: 0px; BORDER-BOTTOM: 0px" height="397" alt="Browse" src="http://lh3.ggpht.com/AndrewShpagin/SByhw2T_WBI/AAAAAAAAAI8/o6AucRUVjEo/Browse_thumb%5B1%5D.jpg" width="414" border="0" /></a></p><p><br />13) Move along motion in pen settings now works with symmetry<br />14) Stability improvements</p><p>15) It is possible to tweak uv-set in View texture mode. You can do it using RMB in wireframe mode.<br />16) Now you can edit not only in 3D, but in UV-plane! It is really complex change. Almost all tools support work in 2D and 3D. Just open View->View color texture and see how it works.<br />17) You can make seamless plane texturing in uv-plane! 3D-Coat now can be used very easily to tile textures and make relief. Just import plane and come to View->View color texture.<br />18) Hide/unhide/Fill can be applied to texture island (cluster)<br />19) Additional view mode for texture in UV - layout: shaded model</p><p>20) texture editor/viewer is in different movable/resizable window<br />21) shift - constrains for horisontal/verlical/diaginal movements of the pen.

The list of features is <a href="http://www.3d-coat.com/news2_08.html">there </a>.<br />2) First newsletters was sent to customers.<br />3) I am seriously thinking about porting to Mac. It is not easy task, but I am seekeng for solution.<br />3) Now I am working over merging additional objects into scene (I hope to finist in 3-4 days). It opens a great perspective - adding new geometry in scene. Lofted tubes made with splines, boolean combining. The last thing - not so quick.<br />4) One of goals - improvement of materials - painting using photo. I want to make possibility to distort image using grid. It will allow to fit image on object very precisely.<br />5) I like Wink, I have already made several tutorials<br /><a href="http://www.3d-coat.com/files/Tut1/Interface.htm" target="_blank">www.3d-coat.com/files/Tut1/Interface.htm</a> - Interface basics<br /><a href="http://www.3d-coat.com/files/Tut2/Curves.htm" target="_blank">www.3d-coat.com/files/Tut2/Curves.htm</a> (30 mb) - Big tutorial about curves<br /><a href="http://www.3d-coat.com/files/Tut3/Ornament.htm" target="_blank">http://www.3d-coat.com/files/Tut3/Ornament.htm</a> - using patterns and curves<br /><a href="http://www.3d-coat.com/files/Tut6/HardCurve.htm" target="_blank">http://www.3d-coat.com/files/Tut6/HardCurve.htm</a> - hard edges with curves<br /><a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.3d-coat.com/files/Tut4/DefineKey.htm" target="_blank">http://www.3d-coat.com/files/Tut4/DefineKey.htm</a> - how to define hotkey<br /><a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.3d-coat.com/files/Tut4/PaintCavity.htm" target="_blank">http://www.3d-coat.com/files/Tut4/PaintCavity.htm</a> - cavity paintingAndrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com1tag:blogger.com,1999:blog-4587608169864457694.post-38840432216984914442008-03-26T08:57:00.005+02:002008-03-26T09:41:13.546+02:00The brief news, for someone it are not news :)<br /><br />1) 3D - Brush has become 3D - Coat to avoid any problems in trademark registering. Thank to Mikael Strom for new logo! There was soooo long <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=837">discussion</a> and big <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=830">battle</a> over new name.<br />2) new <a href="http://www.3d-coat.com/">web site</a> is open. (<a href="http://www.3d-coat.com/">http://www.3d-coat.com/</a>)<br />3) 2.07 is out. Look the features <a href="http://www.3d-coat.com/news2_07.html">there</a>.<br />4) 2.08 is almost done. Visit <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=918&pid=3249&st=0&#entry3249">forum</a> to see the progress.<br />5) Almost all downloads are now form USA-based server, site is now distributed on 2 servers.<br /><br />What is in process now?<br /><br />1) Interface is becoming fully customable. I like idea of Wings 3D where hotkeys for all actions are defined using "Ins". I use "End" for the same purpose because "Ins" is by default bind to fill layer.<br />2) UV-set could be exported/imported<br />3) LW compartability improved - now you can use models with multiple uv-sets (but no more then one uv-set per face)<br />4) One long-playing bug is fixed - spikes on the edge between long and short polygones.<br />5) Curves have got important improvement - now you can put any picture along spline. You can see it <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?s=91d3d919f257a16ae7634f4beec523cd&showtopic=918&pid=3249&st=0&#entry3249">there</a> .<br />6) I have found the coolest program called <a href="http://www.debugmode.com/wink/">Wink</a> to make tutorials (thank to <a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=912&pid=3238&st=0&#entry3238">digman</a>). Can't wait to make some flesh/video-tutorials.<br />7) We paln to spent some money on advertising since 1-st of april, I hope it will help to distribute 3DC. Till now we have spent only 5$ on advertising. Have great idea on advert? Write me.<br />8) Japanese website and transtlation is coming very soon.<br />9)2.08 hints will be fully translated in russian.<br />10) We plan to add some trial period to demo (maybe 6-12 hours of work time). After trial it will work like demo.<br />11) The price will grow significantly from 1-st of April. It will be 120$. Educational version will be available for 89$ (no commercial usage, layers amount limitation).Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com0tag:blogger.com,1999:blog-4587608169864457694.post-35387538257064405552008-02-13T10:54:00.002+02:002008-02-13T11:00:05.823+02:00Recently 2.05 and 2.06was done. There are so m any features in pictures that it is better to give a links to the complete description:<br />2.05 features<br /><a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=760">http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=760</a><br />2.06 features<br /><a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=801&st=0">http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=801&st=0</a><br /><br />Now I plan to add new import option - smooth uv-set like it is described there:<br /><br /><a href="http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=802">http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=802</a><br /><br />Also, it may be interesting for you, I plan to add the next set of features in future:<br /><br />- merging new objects into scene<br />- retopologisation<br />- more complete uv-mapping<br />- memory consumption optimisation, so that every face on layer will contaion only required subset of information (color or geometry)<br />- procedural layers (text layers, curve layers, parametrical materials layers etc)- make blending options like in PS (with same names)<br />- plugins system<br />- more filters (now you have 3 filters - adjust HSV, smooth, sharpen)<br />- tweaking in low-poly mode<br />- hairs and fur (maybe in 3.xx version)<br />- volumetrical sculpting (in 3.xx version) - work wth volume, not surface, so that you will be able to make holes or change topology as you wish.<br /><br />It is a big piece of work, so please don't wait all this in 2.07 :).Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com2tag:blogger.com,1999:blog-4587608169864457694.post-24058515826604184502008-01-31T11:15:00.000+02:002008-01-31T11:18:26.109+02:00The kingdom of arrowsI have add the new curve profile - arrow.

The main feature of the version is auto-subdivision of geometry on comples parts of surface to acieve better displecement. To understad it better I will tell first how 3D-Brush renders the model. The main idea of 3d-brush is that high poly geometry (2-8 millions of polygones) is used to get normalmap, but actually for render less polygonal geometry is used. So there are actual mesh and carcass mesh (20-80 K of polygons). Now you can control the resolution of carcass mesh and of high hpoly mesh. I have made many optimisation and now catrass mesh can be up to 1 million of polygons. But usually you don't need so much polygons for carcass because now 3DB performs additional subdivision on curved faces. But it even makes something better then usual subdivision. You know that during subdivision you should add one point to tyhe center of the face and one point to every edge. In usual sceme every point will be add in the middle of the face/edge. But in my sceme points on face and edges will be inserted in the most displaced positions. It allows to get much better displaced geometry. I can illustrate it ising screenshots:<br /><br /><div><div>1) Usual stroke over plane. You can see disortions on the sharp edge.</div><img id="BLOGGER_PHOTO_ID_5160434791561974834" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgU1-AJ9X4B3yO5uixz6WCSknKtRIdpgFCntGay8LCw1nRNvSnevUvjeQrmdBEyLw28NhGavgG_WolJTBweq26u9SCW8DDVSvjLMd50EO711w3jPXORh0Ldvm68a9TJ24Kc3VLxV2vgbJyv/s400/adapt-subd-rough.jpg" border="0" /><br /><div></div><br /><div>2) The same stroke with adaptive geometry:<img id="BLOGGER_PHOTO_ID_5160433966928253986" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhR23bf_KJDt2xSR9yEvlgZ0W4sYq87vNQenVkAiX45sXuI8b9ARmq3_TrP9axR-MBY-oFcztHJXHnZ-DySpdGogsbMXTUrqzCLVg-ndx77HT0qpyUBO0jdLd9_QlDep0MKinZMtc-mACtF/s400/adapt-subd-precise-wire.jpg" border="0" /></div></div><br /><br />3) The same without wireframe:<br /><img id="BLOGGER_PHOTO_ID_5160434989130470466" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgO7f9DEXnhmwEPjIp3gjdGvRsWlXVD1CQYWiz0PI4eEKh-4PRC-EMEQ303ZbmxKOFmwPflHTjndPqn22VH62ocExvku2gu5eweCRJlz05_R3H0BvyQxToC2W8e31oqzKYOLhdiIrJZt2xR/s400/adapt-subd-precise.jpg" border="0" />Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com0tag:blogger.com,1999:blog-4587608169864457694.post-76052070513508523562008-01-04T15:41:00.001+02:002008-01-31T11:20:07.028+02:00Texture baking tutorialI want to tell several words why baking tool is so important. Baking tool is especially important if you want to get a texture for low-poly mesh as a result. Let us take for example sphere and draw the strip over it like it is shown below:<br /><img id="BLOGGER_PHOTO_ID_5151616210875815138" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjyjn9iDQlmmCJUGKgqJ_aM6uNOGih_Ou0jNBhhIep1hJ_P1RAr7lIQ1no2Embcm6d45QVv1re7ZjvWQdxscMBO4MdB99pf6PuF5LQ8pMonb1tv9GvlZfIiXUgQ9i1qTz3W7eytIt0-VYhQ/s400/Sphere_strip.jpg" border="0" /> Then we should go to sculpt tool and distort it slightly using drag tool: <img id="BLOGGER_PHOTO_ID_5151617056984372466" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiHSGEO7SxQ9v9e-vCizPdz4NZ3A1zY-hkTZ-wIOWMDs84zafPNsvn7EHjeU-3Z0kJPNP7jvG48k-yKYRpGRawrsDLlg0f4gS7884800EevMzNF5CQAYC1ssFOVa5AfuwwNhNEKVi_DFhHh/s400/Sphere_strip1.jpg" border="0" /><br /><br /><br />Then we should enter into low-poly mode. What will you see?<br /><img id="BLOGGER_PHOTO_ID_5151617353337115906" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgk5m3cQ_YK4-YZ0BOaOOrB5rU9MxtaeU6E9DKD5yDTDSvWQK7_6d8VBqkvxKmy-Zy8r8yszRa7OObJiYzWRNWgalnrEnmVAesSBcs4o3VGx5FHjk6Nztk-Sd3H5gSzB_vukNlNvraB5Wj1/s400/Sphere_strip2.jpg" border="0" /><br /><br />It is because you have distorted geometry, but texture is not distorted, so mesh looks improperly in low-poly mode. In thins case baking tool can help you. You should project new high-poly distorted mesh onto low-poly mesh. In this way you will get distorted textures. Please compare the result of usual export of normalmap texture with result of baking tool:<br /><br /><br />Simple export result:<br /><img id="BLOGGER_PHOTO_ID_5151617731294237970" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQTkMLQi23LqetkxmE3d6Iw77x0lCJE_pzt9V370dJCSaaHOOYJ_XQ164x7iNEjXhAU6Ljcxjf-9_E4F-cdWQWGDB34vyQTqKy6eJDbt05cdivlpQfnD2KkX0Z08RCfrO2s-dHx9sBYjy5/s400/Sphere_simp_export.jpg" border="0" /><br />Baking tool result:<br /><img id="BLOGGER_PHOTO_ID_5151617907387897122" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgp57T28IQMKB6bys7Z5UpHpbLia4ow0odrRHpbmzaYoqhQaOfsx0VaX6elJvDwhcnY0DDacEjMvS4C3y6FC7ECGCBLu0tLB3zD4r947ceVtVcbv2I6nVUvofREhSE5dvqs4uoVG7HcBMBm/s400/Sphere_bake_export.jpg" border="0" /> The differene is obvious - you have got the correct normal map using baking tool. The options for taking that normalmap are below:<br /><br />[x] Use current low-poly mesh...<br />[ ] Use original positions ...<br />[ ] Smooth mesh<br /><br />The options should be other if you need displacement:<br /><br />[x] Use current low poly mesh<br />[ ] Use original positions...<br />[x] Smooth mesh<br />[x] Preserve positions ...<br /><br />But the result will be better if you don't need displacement and need only normalmap. It is because of getting displacement is not trivial operation and mesh should be smoothed before. It is required because the displacement is difference between mesh and smoothed surface. I think that simple example shows you why baking tool is so important.Andrew Shpaginhttp://www.blogger.com/profile/05202889417059549137noreply@blogger.com1
