* 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.
|
|
|
