No, its not. The spec does not guarantee the tesselation of a quad, and interpolation depends on the tesselation. In fact the spec doesn't mention tesselation at all, although most/all implementations will break quads and polys into triangles. Uday Verma wrote: Oh....and just because I've been there, if you try to do this with a quad and you specify different vertex colors for all four verts, different drivers can give you different results because they may triangulate the quad differently. I am not sure if I understand this. Did you actually see this? If this happens its a serious problem with OpenGL conformance. -Uday ----- FAQ and OpenGL Resources at: http://www.geocities.com/SiliconValley/Hills/9956/OpenGL -- Author: Michael I Gold INET: [email protected] Fat City Hosting, San Diego, California -- http://www.fatcity.com --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [email protected] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB OPENGL-GAMEDEV-L (or the name of mailing list you want to be removed from).
