Question:
What is the difference between VRML 1.0 and 2.0?
Answer:
VRML 1.0 worlds are static environments in which you can move around and click on objects to link to other URLs. VRML 2.0 extends VRML with animation, behaviors, sensors and sounds.
There are some new geometry primitives as well as support for collision detection. The VRML 2.0 scene graph has been modified to support PC rendering systems more efficiently.
