--- Comment #43 from Misha Koshelev misha680@gmail.com 2010-07-26 21:41:44 --- In case anyone is interested, I have found a very nice resource for the rectangular and triangular patches: http://www.xmission.com/~legalize/book/download/05-Modeling.pdf
In fact, this book is quite excellent for anyone wishing to learn D3DX (or to implement it for Wine). http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/
Thank you Misha
