This is part of the code I have in my drawing function:
glRotated(plane_x,1,0,0);
glRotated(plane_y,0,1,0);
double eqn[4] = {0.0, 1.0, tan(Plane_Angle*pi/180.0), 0.0};
glClipPlane(GL_CLIP_PLANE0, eqn);
if(makecut==1)
{
glEnable(GL_CLIP_PLANE0);
}
else if(makecut==0)
{
glDisable(GL_CLIP_PLANE0);
}
glRotated(X_Angle,1.0,0.0,0.0);
glRotated(Y_Angle,0.0,1.0,0.0);
//Draw the rest of the scene
plane_x and plane_y start out with a value of zero. X_Angle and Y_Angle are incremented and decremented by moving the mouse. I’ve coded in another function so that after the cut is made (makecut=1) plane_x and plane_y start to increase and decrease at the same rate as X_Angle and Y_Angle. This way when I rotate the cut scene, the clipping plane should rotate the same way and I should see the same objects clipped no matter how I rotate. But this doesn’t happen, the clipping plane stays where it is and the result of rotating is that different parts of the scene appear and disappear…why doesn’t the clipping plane rotate also?? And I’m positive that the other functions are all fine.
