986 * The problem is that OpenGL does not offer a direct way to return the tesselated primitives,
987 * and they can't be sent off for rendering directly either. Tesselating is slow, so we want
988 * to cache the patches in a vertex buffer. But more importantly, gl can't bind generated
989 * attributes to numbered shader attributes, so we have to store them and rebind them as needed
992 * To read back, the opengl feedback mode is used. This creates a problem because we want
993 * untransformed, unlit vertices, but feedback runs everything through transform and lighting.
994 * Thus disable lighting and set identity matrices to get unmodified colors and positions.
995 * To overcome clipping find the biggest x, y and z values of the vertices in the patch and scale
996 * them to [-1.0;+1.0] and set the viewport up to scale them back.
998 * Normals are more tricky: Draw white vertices with 3 directional lights, and calculate the
999 * resulting colors back to the normals.
1001 * NOTE: This function activates a context for blitting, modifies matrices & viewport, but
1002 * does not restore it because normally a draw follows immediately afterwards. The caller is
1003 * responsible of taking care that either the gl states are restored, or the context activated
1004 * for drawing to reset the lastWasBlit flag.
