gSPZSetAmbient
gSPZSetDefuse
Format
gSPZSetAmbient(Gfx *gp, u32 umem, Ambient *ambient); gSPZSetDefuse(Gfx *gp, u32 umem, u32 lid, Light *defuse);Arguments
- gp is the pointer to the graphics display list

These Z-Sort microcode GBI macros write ambient light (environment light) data or defuse light (planar diffused light) data to the user area. The light data area is protected in advance in the user area. Its size depends on the number of defuse lights and whether the environment is mapped. It is calculated as follows.
(Light data area size) = 8 + 24 * (number of Defuse lights) + ((environment mapping)? 48 : 0));For detailed information on these macros, please see the "Z-Sort Microcode" area of the N64 Programming Manual.
