guAlign
Format
#include "gu.h" void guAlign(Mtx m, float a, float x, float y, float z)Arguments
- m is the resulting 4x4 matrix
- a is the angle of the rotation around the alignment vector, in radians
- x,y,z specify the vector to align the negative Z axis to
It returns a fixed-point modeling matrix (m) that can be used to align the model with a vector, plus a rotation around that vector. The vector need not be normalized, and the angle should be in radians. For a detailed description of the fixed-point matrix format, see gSPMatrix.
