Hi,
i am totally new in programing OpenGL-Stuff.
I try to program a cool featured tool for windows-desktop. Hope that i may introduce it here when its finished…
But first i have some questions Of course i have…
I need to simulate an background image behind my “normal” drawn 3d-world. Hope it’s clear what i want to do… I want to draw an image first on the screen and then draw 3d-world above it… I tried so hard to figure out how it should work. But it doesn’t.
I tried to draw the picture in glOrtho()-Mode, switched to 3d-perspective, draw my 3d-scene. but nothing happened. The picture was in Front of my scene…
Then i tried to draw the picture some in the depth of the z-buffer, like anormal 3d-projection. But the problem was that i didn’t know how huge i had to make the textured Quad that there were no empty space between the picture and the window-frame…
I hope i told you clearly about my problem an hope further on that somebody can help me…
By the way, how can i increase or decrease the quality of textures ?
Thanks a lot
