guLookAtReflect
Format#include "gu.h" void guLookAtReflect(Mtx *m, LookAt *l, float xEye, float yEye, float zEye, float xAt, float yAt, float zAt, float xUp, float yUp, float zUp)Arguments
- m is the resulting 4x4 viewing matrix
- l is the pointer to resulting LookAt structure for colors and lookat directions
- xEye, yEye, zEye specify the eye position
- xAt, yAt, zAt specify the center of interest in the direction we are looking
- xUp, yUp, zUp specify the up direction vector
It returns a fixed-point 4x4 viewing matrix (m), and it sets up the LookAt structure with x and y screen space coordinate directions. Use the gSPLookAt macro to tell the RCP how to compute texture coordinates for reflection mapping (with the info in the LookAt struct l). For a detailed description of the fixed-point matrix format, see gSPMatrix.
