Trouble with depth test thingy. help :(

Timmmm · 2001-10-02T14:14:20

Right Ive got this program which draws a large triangle and some lines in a grid 0.1f above it. When I turn on the depth buffer though, it all flickers and stuff. The lines flicker, and some frames either the lines or the triangle aren''t drawn. Ive remembereed to do the following: glClear depthbuffer. glEnable DEPTH_TEST glFlush (not sure if this is neccesary but anyway...) SwapBuffers glDepthFunc (just to make sure) Soooo.... any help? please? Ill pay you... with thingys. Thanks for the help which you *will* give me... Tim.

Arrrrrrrrrrrrrggggg. Ive found the problem !!!
After years (almost) of searching. The problem was that my near clipping plane was too near to the camera. This must have meant that it had to be really small to keep the perspective (I used gluPerspective() ). This probably meant that it was soooo small that it couldn''t do something right cause it was too inaccurate or something. Hell who cares. I changed it to 1.0f (it was 0.1f) and now it works !!! wow .

Hmmm
