View volume

I am a new in OpenGL ES and trying to draw a building rotating about axe Y. My camera is always looking at the origin point (0,0,0). When camera moves close to the bulding or building intercepts left and right clipping planes of the frustum, I don’t see clipped image as expected, but the screen is totaly covered by garbage.
I use Vincent implementation of OpenGL ES and currently buiding my app on PC.

What can be a problem?

Thank you for any help.

What implemention of the OpenGL ES are you using?

I used to have a similar problem…
you may see at - YouTube

I was using an old version of the Vincent and it had a little bug in the clipping. But, i fixed the version i had following hmwill (Hans-Martin Will) instruction.

Let me see if i can find the post.
