| * to cache the patches in a vertex buffer. But more importantly, gl can't bind generated |
| * attributes to numbered shader attributes, so we have to store them and rebind them as needed |
| * in drawprim. |
| * |
| * To read back, the opengl feedback mode is used. This creates a problem because we want |
| * untransformed, unlit vertices, but feedback runs everything through transform and lighting. |
| * Thus disable lighting and set identity matrices to get unmodified colors and positions. |
| * To overcome clipping find the biggest x, y and z values of the vertices in the patch and scale |
| * them to [-1.0;+1.0] and set the viewport up to scale them back. |
| * |
| * Normals are more tricky: Draw white vertices with 3 directional lights, and calculate the |
| * resulting colors back to the normals. |
| * |
| * NOTE: This function activates a context for blitting, modifies matrices & viewport, but |
| * does not restore it because normally a draw follows immediately afterwards. The caller is |
| * responsible of taking care that either the gl states are restored, or the context activated |
| * for drawing to reset the lastWasBlit flag. |
