10.2. Transformation Types

There are many types of transformations.

Translation is a transformation of the xy plane that moves a graphics object toward or away from the origin of the surface in the x- or y-direction. For example, moving an object from point A (x1, y1) to point B (x2, y2) is a translation operation in which an object is being moved (y2 – y1) points in the y-direction.

Rotation moves an object around a fixed angle around the center of the plane.

In the reflection transformation, an object moves to a position in the opposite direction from an axis, along a line perpendicular to the axis. The resulting object is the same distance from the axis as the original point, but in the opposite direction.
