first commit for review and improvements on OSA (anti aliasing) in Blender. http://www.blender3d.org/cms/Rendering_engine.320.0.html Most relevant changes: - full check on subpixel sample locations - all subpixels are fully rendered (gives spec AA, procedural texture AA) - also unified render uses it - removed double-used code for unified render Whether or not this will be optional (better pics, but in some cases slow) is to further evaluate. For raytracing - for example - this cannot be simply done, since the new sampling system made raytrace code much simpler.
