/* Tesselates a high order rectangular patch into single triangles using gl evaluators

|
|
* The problem is that OpenGL does not offer a direct way to return the tesselated primitives,
|
|
* and they can't be sent off for rendering directly either. Tesselating is slow, so we want
|
|
* 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.
