Introductory Trail
This trail is meant for new students, or students who are looking for
simple explanations of the content materials. Each section in here will
also contain links to the appropriate sections in the advanced and programming
sections.
Transformations
A transformation is any operation on a point in space (x, y) that maps the
point's
coordinates into a new set of coordinates (x1, y1). There are several types of
basic transformations that are defined:
Any other transformation that needs to be performed can be achieved by
performing a sequence of the above transformations. Any such sequence of
transformations need not be unique - there can be multiple sequences that
would result in the same final transformation.
