Getting Transformed Vertices In DirectX8

[Jacob Roman]

Using DirectX8, after creating a polygonal object, and transforming it's world coordinates and camera coordinates, how do I obtain the results of the vertices after all of that?

[Jacob Roman]

Do I use D3DDevice.GetTransform or D3DXVec3TransformCoord or something else?

NotMe should be around in a week or so. I think he was up on DX.

I found this though

Transformed Vertex = Model Vertex * World Matrix * Camera Matrix

D3DXVec3Project I think

[Jacob Roman]

No that I think converts World coordinates to Screen coordinates.

When I use D3DXVec3Unproject though, I'm getting Division by zero errors for some unknown reason, even though there is no division and no zeros.

*bump* maybe NoteMe might know

This one dude has code for object selection using the stencil buffer, which he claims is pixel perfect. Unfortunately I can't find where to download his example. All I see is code to do an object selection lasso
