Member artaq Posted December 13, 2008 Member Report Share Posted December 13, 2008 I agree, there is a discussion going on regarding this over at the Luxology forums (http://forums.luxology.com/discussion/topic.aspx?id=30941), appears to follow a lot of the same principals that were being discussed here regarding how 3DCoat (or Andrew rather) should deal with voxel painting... Cool stuff! Quote Link to comment Share on other sites More sharing options...

Advanced Member Jokermax Posted December 13, 2008 Advanced Member Report Share Posted December 13, 2008 On 1st glance reminds of Zbrush AUV tiles a lot - per face mapping, tightly packed with minimal distortion, which assumes you paint on the model directly, which not always an option.

Andrew Shpagin Posted December 14, 2008 Report Share Posted December 14, 2008 It reminds me idea about procedural mapping that was mentioned on this forum earlier (it is one of my goals). The idea is that you are painting not simply color but mask for applying high-frequency material like skin, dinoskin, etc. So yo are painting 1-4 M res vertex map but getting big resolution textures with huge quality (32 x 32k) Quote Link to comment Share on other sites More sharing options...
philnolan3d Posted December 18, 2008 Report Share Posted December 18, 2008 Friend of mine was the lighter for that movie. hehe But really, it looks like a cool technique. Quote Link to comment Share on other sites More sharing options...

I have read PTex paper and it seems that internal 3D-Coat's internal structure is exactly PTex. The only difference is that 3DC projects pTex structure on some uv-set for rendering. I can make uv-less mapping - it is not very hard. Just need to finish VS & Direct painting. Quote Link to comment Share on other sites More sharing options...

Ptex open source release of the library is coming soon. http://www.disneyanimation.com/library/ptex/ RenderMan now supports the Ptex texture format https://renderman.pixar.com/products/tools/rps-new.html Quote Link to comment Share on other sites More sharing options...
