Pops from a matrix stack
#include <ultra64.h> /* gbi.h */ gSPPopMatrix(Gfx *gdl, u32 param) gsSPPopMatrix( u32 param)
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.
If the stack is empty, the command is ignored.
