I am trying to show a sphere in a simulation environment that is based on python and utilizes Qt for its GUI representation and in that GUI lies a 3D visualization region that utilizes OpenGl GLU module to show 3D world. Now I intend to modify this visualization and put a sphere at (0,0,0). This python code uses a class based approach and contains a class that controls visualization portion using OpenGL glu.
I am able to modify the code without errors. I put this code in a mouse event and the event is successfully called and executed (I have verified it). Here is the code:
quadratic = GLU.gluNewQuadric()
GL.glTranslatef(2.75, 0.0, -1.0)
GL.glColor3f(1.0, 0, 0)
GLU.gluSphere(quadratic,100, 10, 10)
but when I run my code there is no sphere in the visualization. Please help me resolve this issue.
