3D Graphics, Animation, Rendering
3D computer graphics are different from 2D computer graphics in that a three-dimensional representation of geometric data is stored in the computer for the purposes of performing calculations and rendering 2D images.
Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life.

Art of Illusion
Art of Illusion is a free, open source 3D modelling and rendering studio. It is written entirely in Java, and should be usable on any Java Virtual Machine which is compatible with J2SE 1.4 or later.
Art of Illusion is a program for creating high quality, photorealistic still images and animations (either in .mov format or as a sequence of still frames which can be joined together using other software to make movie files). Images are produced by rendering scene files. These scene files need to contain some 3-D objects, at least one light so that the objects can be seen and at least one camera, the view from which provides the image. Complex scenes may contain many hundreds of objects and several lights. Files built for animation may have several cameras between which the view is cut to make for an interesting animation sequence.
3-D objects come in 4 basic flavours: Primitives, spline meshes, triangle meshes and tubes, all of which are described in detail later in this manual. Art of Illusion has highly flexible, but easy to use, editors for textures (surface properties such as colour, bumpiness, shininess, transparency etc.) and materials (inner properties for simulating glass, smoke etc.)
Animation of objects within the scene is achieved with a keyframing system including support for skeletons using forward and inverse kinematic animation. Textures can also be animated.
Rendering of the scene file is achieved with a fast raster engine or a high quality raytracer capable of producing photorealistic images. Motion blur, depth of field, Global Illumination and caustic effects are supported.
In addition, Art of Illusion includes a scripting feature allowing the creation of new types of objects and tools amongst virtually unlimited other possibilities via the Beanshell scripting language.
