a screen shot at least would be handy, as well as maybe the relivent code (dont just dump the whole program) in the [ source ][ /source ] tags (without the spaces)

hi, this is pretty much the essence of the code, nothing hard, just wondering if theres some sort of matrix i need to multiply by before or after...

	glBindTexture(GL_TEXTURE_2D,teapot->ID);	glMatrixMode(GL_TEXTURE);	glLoadIdentity();	gluLookAt(1,1,1,-1,-1,-1,sin(temptime),1,0);	glMatrixMode(GL_MODELVIEW);	glutSolidTeapot(1.0f);

sorry cant get a shot!!:S!?
