guMtxXFMF [Function]

Function

guMtxXFMF

Coordinate transformation (floating-point matrix)

Syntax

#include <ultra64.h>        /* gu.h */
void guMtxXFMF(
        float mf[4][4],
        float x,
        float y,
        float z,
        float *ox,
        float *oy,
        float *oz);

Arguments

mf

the 4x4 Matrix

x

x-coordinate to transform

y

y-coordinate to transform

z

z-coordinate to transform

ox

Pointer to resulting x-coordinate

oy

Pointer to resulting y-coordinate

oz

Pointer to resulting z-coordinate

Returned value

None

Description

Transforms one set of coordinates (x, y, z) using the specified matrix. This function provides a useful way to process matrices on the host CPU. When this function is called, the result is the creation of coordinates as shown below:

Fixed-point matrices are handled with the guMtxXFML function.
