J3dLwoParser (3D 1.5.3-pre3-1409021114)

```
 class J3dLwoParser
extends LwoParser
```
This class is responsible for turning Lightwave geometry data into Java3D geometry. It is a subclass of LwoObject and calls that superclass when first instantiated to parse the binary file and turn it into intermediate data structures. J3dLwoParser then goes through those data structures and turns them into Java3D objects. For each ShapeHolder object created by the parent class, this class retrieves the geometry data and associated surface data, creates the appropriate Geometry object (usually IndexedTriangleFanArray, unless the object is points or lines), including calculating normals for the polygons and sets up the Appearance according to the surface parameters (including calculating texture coordinates if necessary).
