Dynamic view-dependent surface tessellation.Exact limit evaluation of points/normals/shading data.Feature adaptive refinement as described by the Microsoft/Pixar research collaboration. Jonathan Lampel shows off using OpenSubDiv in the latest release of Blender.The release candidate adds the following in addition to that supported by beta: OpenSubdiv is a set of libraries developed by Pixar Animation Studios. The requires significantly less GPU memory than uniform subdivisions as tessellation hardware dices those cubic patches on the fly while drawing and doesn't need to store the high resolution surface geometry. opensubdiv (graphics/opensubdiv) Add to my watchlist 0. This fitting process is done adaptively, so areas of the mesh that are all quads and regular aren’t subdivided at all, and the detail is clustered close to features that require it, such as creases, extrordinary points, hierarchical edits, boundaries, and corners. The release version of OpenSubdiv raises the performance bar to what we believe is the maximum level by computing cubic patches that are supported directly in hardware with tessellation shaders. OpenSubDiv in Blender will help animators who need realtime viewport playback with final mesh subdivisions. Since its release, OpenSubDiv has been finding its way into many applications, offering GPU accelerated viewport display for subdivision surfaces. This makes it impossible to make Blender working with OpenSubdiv on OSX due to policy from Apple which forces everyone to drop older OpenGL code if newer API is used in application. Jonathan Lampel shows off using OpenSubDiv in the latest release of Blender. The release candidate has all APIs and features in place and will receive stability bug fixes and optimizations before 1.0 release targetting January 2013. No OSX support, Historically Blender is using rather old OpenGL API and OpenSubdiv is using OpenGL 4. The OpenSubdiv release candidate is open for SIGGRAPH Asia 2012.
