[gl4java-usergroup] two quads with same coords

[Thorsten R. <ni...@gm...>]

Hi again,

just a simple question:

Does somebody know how to render two quads with the same coords values
_without_ gfx issues?
Dependant on camera position both quads will intersect each other in "small
triangles" (some fragments are drawn from the first quad, other parts from
the second).

I have to enable GL_DEPTH_TEST by other reasons.
I've found something about a glPolygonOffset() but I don't understand the
docu. After (trial and error) playing with the arguments it works when the
quads lies parallel to the x- and y-axis. But when rotating ...
Also glDepthFunc(GL_LEQUAL) doesn't solve the problem.

Any ideas ? Is it too easy ? Please give me a hint ...

ciao, Thorsten
