Class ShapeHolder

java.lang.Object

com.sun.j3d.loaders.lw3d.ParserObject

com.sun.j3d.loaders.lw3d.ShapeHolder

 class ShapeHolder
extends ParserObject

This class holds all of the vertex/facet/normal/surface-reference data for a particular object. It has utilities to calculate facet normals, but this is no longer in use since using the new GeomInfo utilities.

Methods

Modifier and Type	Method and Description
(package private) void	calcNormals() This method calculates facet normals for the geometry.
(package private) void	createArrays(boolean reverseWinding) Constructs geometry arrays given a winding rule (it turns out that lw3d winding is opposite of j3d winding, so this is always set to true in J3dLwoParser)
(package private) void	nullify() Force gc on all array objects
(package private) void	printGeometryData(LwoSurface surface) Print out (to stdout) the geometry data (coords, indices, and facet sizes).

Method Detail

printGeometryData

void printGeometryData(LwoSurface surface)

Print out (to stdout) the geometry data (coords, indices, and facet sizes). This is a debugging utility.

createArrays

void createArrays(boolean reverseWinding)

Constructs geometry arrays given a winding rule (it turns out that lw3d winding is opposite of j3d winding, so this is always set to true in J3dLwoParser)

nullify

void nullify()

Force gc on all array objects

calcNormals

void calcNormals()

This method calculates facet normals for the geometry. It is no longer used, as we're now using the GeometryInfo utility to calculate smooth normals
