20 Setting Up Transformation Matrices
Q3Matrix4x4_SetRotateAboutAxis
function to configure a 4-by-4 rotate-about-axis transformation matrix.
TQ3Matrix4x4 *Q3Matrix4x4_SetRotateAboutAxis ( TQ3Matrix4x4 *matrix4x4, const TQ3Point3D *origin, const TQ3Vector3D *orientation, float angle);matrix4x4
A 4-by-4 matrix.origin
The desired origin of rotation.orientation
The desired orientation of the axis of rotation.angle
The desired angle of rotation, in radians.
Q3Matrix4x4_SetRotateAboutAxis
function returns, as its function result and in the matrix4x4
parameter, an rotate-about-axis matrix that rotates an object by the angle angle
around the axis determined by the point origin
and the orientation orientation
.
