Object Representation

How the objects are represented in the object database has a major impact on the rendering performance, the quality of the generated image and the time needed to construct the virtual world database.

The milk cartons can be represented in two ways. In the first method, the milk cartons are represented as a milk carton object. The scene designer need only specify the dimension, the texture map and the color. Each object in turn is composed of number of rectangular and triangular 3D sub-objects. The sub-object is positioned relative to an anchor point of the object.

These objects are analytically defined, so there is no limit on resolving the details of the object. The resolution of the object is bounded instead by the surface texture map.
