how to know depth test result
Author
Is it possible to know the depth test result after rendering a triangle, ie:
in the display
...
glBegin(GL_TRIANGLES);
...
glEnd();
->i want to know at this moment if the triangle i have just rendered is visible (partially) or not (depending on the result of the depth test).
Or is it possible to know the depth test result only on a vertex?
Thanks in advance.
the occulsion test is what you'll want for that kinda of thing, i cant remember the extension name off the top of my head by its an ARB extension you want to search for

Thanks a lot, it works fine. For those who wants an example code using it, go to http://www.g-truc.net/tuts.html#pack1 (it's a french site)
