Writing to depth buffer


I would like to write a texture to the depth buffer in OpenGL ES 1.1, but I can’t find any way to do so.

The reason I want to do this is that I’ve been writing a voxel engine in which I want to write my own depth information. Then I would like to draw sprite quads through OpenGL ES, and thus I need the depth info.

Any help appreciated!


Unfortunately this is not possible with OpenGL ES 1.1.
