Q3Matrix4x4_SetRotateAboutPoint
You can use the Q3Matrix4x4_SetRotateAboutPoint function to configure a 4-by-4 rotation transformation matrix.
TQ3Matrix4x4 *Q3Matrix4x4_SetRotateAboutPoint (
TQ3Matrix4x4 *matrix4x4,
const TQ3Point3D *origin,
float xAngle,
float yAngle,
float zAngle);
matrix4x4
- A 4-by-4 matrix.
origin
- The desired origin of rotation.
xAngle
- The desired angle of rotation around the x component of
origin, in radians.
yAngle
- The desired angle of rotation around the y component of
origin, in radians.
zAngle
- The desired angle of rotation around the z component of
origin, in radians.
DESCRIPTION
The Q3Matrix4x4_SetRotateAboutPoint function returns, as its function result and in the matrix4x4 parameter, a rotation matrix that rotates an object by the specified angle around the point origin.
