Function
gSPLookAt, gsSPLookAt, gSPLookAtX, gsSPLookAtX, gSPLookAtY, gsSPLookAtY
Loads a LookAt structure into RSP for specular highlighting and reflection mapping.
Syntax
#include "gbi.h" typedef union { Light l[2]; } LookAt; gSPLookAt(Gfx *gdl, LookAt *l) gsSPLookAt( LookAt *l)
Arguments
Description
The gSPLookAt macro loads a LookAt structure into the light buffer. This structure is required for specular highlighting or reflection mapping.
The LookAt structure can be set up with the utility macros guLookAtHilite and guLookAtReflect, or it can be set up directly with the gdSPDefLookAt macro. The LookAt structure contains colors as well as x and y screen space coordinate directions.
Note
Niether gSPLookAtX nor gSPLookAtY are open to application developers. These are embedded in the gSPLookAt macro.
