Does anyone have any good reading on the subject ( preferably without having to buy another book - the two I have on DX9 gloss over it with a load of old pony about the SDK functions which create one for you automatically. Great, but I bloody want to create my own! )
Something with a detailed explanation about what goes in each cell of the matrix, and a few examples would be a good start. I'm sure I can use projection matrices to force the aspect ratio of my game to be consistent between all monitor aspect ratios, but I can't find any documentation on it at all. All I end up with is explanations like "takes a projection matrix as the parameter )
The helper function(s) won't work for me. I need to understand all the issues here. Clipping, FOV, the whole kit.
