guFrustum

Syntax

#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

Explanation
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.
