setToRotation method
Sets this transformation to be a rotation around the origin. A positive rotation angle corresponds to a counter-clockwise rotation. The transformation matrix for a rotation by an angle theta has the value:
| cos(theta) -sin(theta) 0 | | sin(theta) cos(theta) 0 | | 0 0 1 |
@param theta the rotation angle, in radians @return this transformation, with an updated matrix
Implementation
AffineTransformation setToRotation(double theta) {
setToRotationSinCos(math.sin(theta), math.cos(theta));
return this;
}
