VRML
Note that all references to VRML in this lecture are references to VRML 2.0/97
Key Concepts
- Virtual environments are realised by a player (browser) that interprets, executes, and presents VRML files
- A VRML file contains at least a header and nodes
- Nodes are arranged in a 'scene graph'
- Nodes have field and field values that describe their attributes
- Shape nodes are used to define shapes with appearance and geometry
- Predefined geometry nodes are Box, Cone, Cylinder and Sphere nodes
- Complex shapes can be built by grouping predefined shapes together and/or using a PointSet, IndexedLineSet, or a IndexedFaceSet, and/or using an Extrusion node
