20 Setting Up Transformation Matrices

20 Q3Matrix4x4_SetRotateVectorToVector

You can use the Q3Matrix4x4_SetRotateVectorToVector function to configure a 4-by-4 transformation matrix that rotates objects around the origin in such a way that a transformed vector matches a given vector.

TQ3Matrix4x4 *Q3Matrix4x4_SetRotateVectorToVector (
TQ3Matrix4x4 *matrix4x4, 
const TQ3Vector3D *v1, 
const TQ3Vector3D *v2);
matrix4x4 A 4-by-4 matrix.
v1 A three-dimensional vector.
v2 A three-dimensional vector.

DESCRIPTION


The Q3Matrix4x4_SetRotateVectorToVector function returns, as its function result and in the matrix4x4 parameter, a rotational matrix that rotates objects around the origin in such a way that the transformed vector v1 matches the vector v2. Both v1 and v2 should be normalized.
