I am about to pull my hair out!!!!! With DX I am trying to do what I have in OpenGL and its driving me nuts. So far I am trying to use view frutsum culling and patches for my terrain and thats not working out... I can render one huge chunk and when I try to render more than one chunk my mesh is all screwed up! I can't figure out the DrawIndexedPrimitive(). One book I read says the parameters are for the VB and another the IB. Then one site says the minIndex + this = that?????? Good grief GL's calls are much better if thats the case. I am not sure what I should be sending to the parameters with all the confusion and have tried almost ever combo and still get nothing... Any ideas you DX gurus?
On the GL front looks like Khronos stated today that GL will run full force under Vista and may actually fun faster they say. So will Aero UI work with GL now also? This bit of info would be nice to know.
Anyway back to pull hair out... :(
