guFrustum
Format#include "gu.h" void guFrustum(Mtx m, float l, float r, float b, float t, float n, float f float scale)Arguments
- m is the resulting 4x4 projection matrix
- l,r are the left and right vertical clipping plane coordinates at the "near" plane
- b,t are the bottom and top horizontal clipping plane coordinates at the "near" plane
- n,f are distances to the near and far clipping planes
- scale is the scale for each element of the matrix. The scale can be used to improve precision in the RSP fixed-point arithmetic
It computes a perspective projection matrix and returns a fixed-point 4x4 matrix (m). For a detailed description of the fixed-point matrix format, see gSPMatrix.
