thanks in advance
following is an circle coding in 2d
#define GL_PI 3.141592654
#define GL_PI_2 GL_PI * 2
float fRadius = m_fControlRadius / 2 ;
glHint(GL_LINE_SMOOTH_HINT, GL_NICEST) ;
for (float pheta = 0.0f; pheta - GL_PI_2 < .001; pheta +=fAngleIncr)
float x = fRadius * cos (pheta) ;
float y = fRadius * sin (pheta) ;
glEnd () ;
