Class ModelDef

java.lang.Object
  com.threerings.opengl.model.tools.ModelDef

public class ModelDef
extends Object

An intermediate representation for models used to store data parsed from XML.

Nested Class Summary

static class	ModelDef.BoneWeight The influence of a single bone on a vertex.
static class	ModelDef.Extra An extra bit of data associated with a vertex.
protected static class	ModelDef.HashArrayList<E> Accelerates ArrayList.indexOf(java.lang.Object), ArrayList.contains(java.lang.Object), and ArrayList.remove(int) using an internal hash map (assumes that all elements of the list are unique and non-null).
static class	ModelDef.NodeDef Represents a node without geometry.
static class	ModelDef.SkinMeshDef Represents a triangle mesh whose vertices are influenced by sets of bones.
static class	ModelDef.SkinVertex A vertex with bone influences.
static class	ModelDef.SpatialDef The abstract base class of the nodes stored in the model definition.
protected static class	ModelDef.Triangle Represents a triangle for processing purposes.
static class	ModelDef.TriMeshDef Represents a triangle mesh.
static class	ModelDef.Vertex A single vertex in a mesh.

Field Summary

protected static int	MAX_BONE_COUNT The maximum number of bones that may influence a single mesh.
HashMap<String,ModelDef.SpatialDef>	spatials The nodes in the model, mapped by name.

Constructor Summary
