Abstract
CarSim is an automatic text-to-scene
conversion system. It analyzes written
descriptions of car accidents and synthe-
sizes 3D scenes of them. The conver-
sion process ... mental images.
Animated 3D graphics have some advantages
for the visualization of information. They can re-
produce a real scene more accurately and render a
sequence of events.
