An abstract implementation of an IndexedTriangleSet

The node is defined by X3D as:

 IndexedTriangleSet : X3DComposedGeometryNode {

Constructor Details

BaseIndexedTriangleSet

protected BaseIndexedTriangleSet()

Construct a default instance of this class with the bind flag set to false and no time information set (effective value of zero).

BaseIndexedTriangleSet

protected BaseIndexedTriangleSet(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not the same type, an exception will be thrown.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - Incorrect Node Type

Method Details

getFieldIndex

public int getFieldIndex(String fieldName)

Get the index of the given field name. If the name does not exist for this node then return a value of -1.

Parameters:

fieldName - The name of the field we want the index from

Returns:

The index of the field name or -1

getNodeFieldIndices

public int[] getNodeFieldIndices()

Get the list of indices that correspond to fields that contain nodes ie MFNode and SFNode). Used for blind scene graph traversal without needing to spend time querying for all fields etc. If a node does not have any fields that contain nodes, this shall return null. The field list covers all field types, regardless of whether they are readable or not at the VRML-level.

Returns:

The list of field indices that correspond to SF/MFnode fields or null if none

getNumFields

public int getNumFields()

Get the number of fields.

Returns:

The number of fields.

getFieldDeclaration

public VRMLFieldDeclaration getFieldDeclaration(int index)

Get the declaration of the field at the given index. This allows for reverse lookup if needed. If the field does not exist, this will give a value of null.

Parameters:

index - The index of the field to get information

Returns:

A representation of this field's information

updateIndexMaps

protected void updateIndexMaps()

Update the index listing for the faces. This should only be called when the index list has changed. It sets up all the internal mappings for faces to index lists if normalPerVertex is false.
