## guFrustumF

Syntax

    #include "gu.h"

    void guFrustumF(float m[4][4],
       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 floating-point 4x4 matrix (m).
