errors with Direct3D Retained Mode

Post by DGE Smit » Wed, 04 Feb 1998 04:00:00


I've spent the last week trying and failing to get a Direct3D retained
mode application to work properly under BCB.
Everything works fine until an object moves partially outside the
viewport. Instead of it being clipped, I get a 'invalid floating point
operation' error.
After giving up on my own code, I converted one of the example
applications which came with the D3D SDK to run under BCB and altered it
so that the object would move outside the viewport. I get the same error
and can't figure out what I've done wrong.
I was wondering if anyone else had come across a similar problem before.
Any help would be much appreciated.

1. Direct3D Retained Mode

Can anyone point me at any on-line resources which might help me to gently
transition from OpenGL to Direct3D retained mode? Failing that can anyone
recommend a good book?
First impressions are that there is a very strong (almost one to one)
correspondence. Would anyone care to point out the main differences?

Many thanks
