A 3D scene is a collection of ``material'' objects,
such as surfaces (constructed by a number of polygons), points and lines,
living in 3D space. The two 3D scene formats I have used in this project
Inventor and VRML are explained further
Inventor is two things:
I will only be using Inventor in the latter sense, i.e. as a
file format, or programming language.
- An object-oriented toolkit for developing interactive,
- A file format for exchanging 3D data among applications.
A technical note:
Inventor V1.0 is called IRIS Inventor, whereas
Inventor V2.0 is called Open Inventor. I will only be
using Inventor V1.0, and I will refer to that as Inventor.
What I call a 3D scene is in Inventor terminology called
Information about Inventor can be found at the
Open Inventor page.
- VRML (Virtual Reality Modeling Language):
VRML is the standard for 3D scenes on the Web.
It is based on Inventor. It has a subset of the Inventor commands,
and some additional commands which are not found in Inventor;
this will be exemplified later.
What I call a 3D scene is in VRML terminology called
When I refer to VRML, I mean VRML V1.0;
the specifications are available
