View Full Version : Draw Bitmaps
I am currently writing a Machine Vision App for tracking people. I am thinking of using OpenGL for visualisation and GLUT to handle the windowing.
My question is is it easy to draw a bitmap image into a GLUT window? how do I do it?
well, usually glDrawPixels() should work.
or upload your bitmap as texture and draw a quad right over your screen
you could use a 512x512 texture, only use 512x384 res (because that's our magical 0.75 aspect ratio) and then opengl scales it to your respective resolution (if you use different ones)
that's how I did it in fullscreen, but I'd wodner if it won't work in a glut window.

If you would like, I could give you code in GLUT that loads a BMP file and textures it over a quad, done in a glut window. Just email me if you would like the code.

On my site, I've a little exemple who display a BMP like a splash screen.
The function can be imported for GLUT with no problems.

Hi, just seen this, could you have a look at my Q on texture quality...
