D3DXVec3Unproject
Koichi Senada
Today I have a question about D3DXVec3Unproject method described in
DirectX Documentation:
http://msdn.microsoft.com/en-us/library/bb205526.aspx
Could you guys please recommend some tutorials/manuals/samples that
might explain the very details and internal works and theory of this
method?
I am especially intrested about how World / View / Projection matrices
participate in that.
Also the "Pick" sample from the DirectX SDK explanation might help,
especially the ray's vectors computation:
D3DXVECTOR3 vPickRayDir;
D3DXVECTOR3 vPickRayOrig;
Of course, a good tutorial is a tutorial that not just tells what
things are to be put together, but why those are the right things to
do that.
I am sure, the subject is somewhat intersting and covers several
important subjects which are meant to be understood clearly for a wise
DirectX coder.
So I assume there might be some great authors who have written well
about this.
If you guys by any chance have seen such tutorials/articles/manuals/
samples, please let me know about them.
Thanks alot!
