How would you go about drawing a circle in openGL. I’'m sorry, I know it’s a stupid question, but I’ve only been looking at openGL for a week… Thanks

Hello,

this has been done before, methinks. But, ah well, I am in a chirpy mood today, so … <deep breath>:

`glBegin(GL_LINE_LOOP); for(int t=0; t<CIRCLE_RES; t++) { float angle=((float)t/(float)CIRCLE_RES)*2.0*M_PI; glVertex2f(cos(angle), sin(angle)); } glEnd();`

which will draw a unit circle with z=0. SO, you’ll want to scale it and translate it, ‘n’ stuff. But i’m sure you know all that.

cheers,

John
