20 Setting Up Transformation Matrices
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.
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.
