What are profiles?

Profiles are subsets of the x3d specs. They are declared in the x3d tag, like this:

Code:

<X3D version='3.1' profile='Interactive' ...

When you decide to create a scene, you should choose a profile that contains the nodes and functionality you need. It acts as a contract to the viewer (browser) which should protest if it is not capable of supporting that profile.

Current profiles are:

1. Core
2. Full
3. Immersive
4. Interactive
5. Interchange
6. MPEG-4 interactive
