Rendering
Deal with the passive visual primitives (e.g. choose a surface texture)
Choose a rendering technique & landscape (e.g. CityScape, Pixel Map, Isosurface)
Link the dataâs active & passive visual primitives to appropriate landscape attributes (e.g. height of a bar, length of a line, size of a sphere, direction of an arrow)
Implement a lighting model and render the scene (the task of the In3D engine)
