Predefined Objects

IVL has predefined atomic types that the programmer may use to create graphical objects. These types represent all the VRML nodes derived from SoShape and exclude those nodes derived from SoVertexShape. IVL types are given the same name as the corresponding VRML node.

Additional atomic types can be added easily. We have extended the VRML set of primitives to include:

IVL also provides ``environment'' nodes in the form of light sources. The light sources can be placed, transformed, and colored in the same manner as shapes.
