fovySin Sine value of the field-of-view angle (view angle) in y-direction/2
fovyCos Cosine value of the field-of-view angle (view angle) in y-direction/2
aspect Ratio of width of view field to height of view field (aspect ratio: width/height of the field of view)
n Distance from eyepoint to the near clip plane
f Distance from eyepoint to the far clip plane
scaleW Fine adjustment parameter for the view volume
mtx Pointer to the 4x4 matrix

Return Values
