A 2D graphics and animation software
First, a geometric model of a scene is created, then the scene is rendered using realistic coloring and lighting effects. In this lab and the next, you will use an applet called xModels, which deals with the model-construction stage of image creation.
Complex geometric models are built up out of simpler components which are scaled, rotated and positioned in the scene using geometric transformations. Simple geometric shapes like circles and lines are used as a starting point in the modeling process.
These shapes can be combined to form more complex figures that can then be combined to form even more complex scenes.
Scenes constructed from objects in this way can be used in a natural way to produce animations. An animation is just a sequence of frames in which objects move slightly from one frame to the next. When the frames are quickly displayed one after the other, the viewer perceives objects in motion.
