Matrix for homogeneous co-ordinate rotation (anticlockwise) Matrix for homogeneous co-ordinate rotation (clockwise) Matrix for rotation is an anticlockwise direction. Matrix for rotation is a clockwise direction. Polygon: Polygon is rotated by shifting every vertex using the same rotational angle.Ĭurved Lines: Curved Lines are rotated by repositioning of all points and drawing of the curve at new positions.Ĭircle: It can be obtained by center position by the specified angle.Įllipse: Its rotation can be obtained by rotating major and minor axis of an ellipse by the desired angle. Straight Line: Straight Line is rotated by the endpoints with the same angle and redrawing the line between new endpoints. When the object is rotated, then every point of the object is rotated by the same angle. The negative value of the pivot point (rotation angle) rotates an object in a clockwise direction. The positive value of the pivot point (rotation angle) rotates an object in a counter-clockwise (anti-clockwise) direction. It is print about which object is rotated. Rotation point is also called a pivot point. For rotation, we have to specify the angle of rotation and rotation point. Rotation can be clockwise or anticlockwise. It is a process of changing the angle of the object.
