guLookAtReflect

Syntax

#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

Explanation
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.
