Unable to view the 3D rendering on the blackberry simulator while using OpenGLES

I am right now exploring the openGL 开发者_StackOverflow社区ES in the blackberry I am unable to view the 3D rendering on the simulator(9550) but when i upload the cod files on the device it works Kindly help.

Could you also suggest any tutorials for blackberry app development using openGLES?

Thank you, Dheeraj Jami

Finally I found the answer for this problem, The 3D rendering is not visible because my PC didnt have the updated directx version not installed.
