gSPPopMatrix [Macro]

Function

gSPPopMatrix

Pops from a matrix stack

Syntax

#include <ultra64.h>        /* gbi.h */
gSPPopMatrix(Gfx *gdl, u32 param)
gsSPPopMatrix(         u32 param)

Arguments

gdl

the pointer to the graphics display list.

param

the flag field identifying the matrix stack to pop:

G_MTX_MODELVIEW (The modelview matrix stack)

G_MTX_PROJECTION (The projection matrix stack) (not implemented)

Description

Pops from one matrix stack. The modelview matrix stack is 10 levels deep, and the projection matrix stack is 1 level deep (so it is impossible to pop a projection matrix stack). For details, see Section 11.3, "Matrix State," in the N64 Online Programming Manual.

Note

If the stack is empty, the command is ignored.
