This function sets a frustum matrix to *mtx. It uses the Divider. The following diagram shows the matrix that is set.
x scaleW
t |
Y coordinate at the top of the near clipping plane |
b |
Y coordinate at the bottom of the near clipping plane |
l |
X coordinate at the left of the near clipping plane |
r |
X coordinate at the right of the near clipping plane |
n |
The distance from the eyepoint to the near clipping plane |
f |
The distance from the eyepoint to the far clipping plane |
scaleW |
Fine adjustment parameter for the view volume |
mtx |
Pointer to a 4x4 matrix |
None.
