Nodes may contain zero or more fields.
|
|
Each node type defines the type, name, and default value for each of its fields.
|
|
The default value for the field is used if a value for the field is not specified in the VRML file.
|
The order in which the fields of a node are read is not important;
-
for example, "Cube {width2height4depth6}"
-
and "Cube {height4depth6width2}" are equivalent.
|
|
Note that each VRML node uses local coordinates centered at (0,0,0)
|
|
The data implied by the node is placed in 3D world at position and orientation implied by current accumulated transformation
