guTranslate [Function]

Function

guTranslate

Creates a translation modeling matrix (fixed point)

Syntax

#include <ultra64.h>        /* gu.h */
void guTranslate(Mtx *m, float x, float y, float z);

Arguments

m

Pointer to the matrix resulting from the calculation

x

Amount of translation along x-axis

y

Amount of translation along y-axis

z

Amount of translation along z-axis

Returned value

None.

Description

Returns a modeling matrix translated by (x, y, z) to the structure indicated by m. When this function is called, the result is the creation of the following kind of modeling matrix:

For details about the fixed-point format, see gSPMatrix. Floating point is handled by the guTranslateF function.

Comment

The Mtx structure looks like this:

typedef long  Mtx_t[4][4];
typedef union {
     Mtx_t          m;
     long long int  force_structure_alignment;
} Mtx;
