20 Setting Up Transformation Matrices
Q3Matrix3x3_SetRotateAboutPoint
function to configure a 3-by-3 rotation transformation matrix.
TQ3Matrix3x3 *Q3Matrix3x3_SetRotateAboutPoint ( TQ3Matrix3x3 *matrix3x3, const TQ3Point2D *origin, float angle);matrix3x3
A 3-by-3 matrix.origin
The desired origin of rotation.angle
The desired angle of rotation, in radians.
Q3Matrix3x3_SetRotateAboutPoint
function returns, as its function result and in the matrix3x3
parameter, a rotation matrix that rotates an object by the angle angle
around the point origin
