Field Detail

children

protected List<ColladaRenderable> children

Children of this node. Children may be ColladaNode (direct child of this node) or ColladaInstanceNode (reference to a node elsewhere in the current document, or another document).

geometries

protected List<ColladaInstanceGeometry> geometries

Geometries defined in this node.

matrix

protected Matrix matrix

Transform matrix for this node.

shapes

protected List<ColladaMeshShape> shapes

Shape used to render geometry in this node.

Constructor Detail

ColladaNode

public ColladaNode(String ns)

Construct an instance.

Parameters:

ns - the qualifying namespace URI. May be null to indicate no namespace qualification.

Method Detail

createShapes

protected List<ColladaMeshShape> createShapes()

Create shapes to render this node.

Returns:

List shapes. The list may be empty, but will never be null.

createShapesForGeometry

protected void createShapesForGeometry(ColladaInstanceGeometry geomInstance,
                                       List<ColladaMeshShape> shapes)

Create shapes for a geometry.

Parameters:

geomInstance - Geometry for which to create shapes.

shapes - List to collect the new shapes.

getChildren

protected List<ColladaRenderable> getChildren()

Indicates the children of this node. Children may be other node elements contained directly within this node, or other nodes referenced indirectly by a instance_node element.

Returns:

List of children. The list may be empty, but will never be null.

getLocalExtent

public Box getLocalExtent(ColladaTraversalContext tc)

Description copied from class: ColladaAbstractObject

Returns this renderable's model coordinate extent.

Specified by:

getLocalExtent in interface ColladaRenderable

Overrides:

getLocalExtent in class ColladaAbstractObject

Parameters:

tc - The traversal context to use when determining the extent.

Returns:

The model coordinate extent.

getMatrix

protected Matrix getMatrix()

Indicates the transform matrix specified in this node.

Returns:

The matrix specified in this node. Returns the identity matrix if the node does not specify a matrix.

parseDoubleArray

protected double[] parseDoubleArray(String doubleArrayString)

Parse a string of doubles into a double[].

Parameters:

doubleArrayString - String of doubles, separated by whitespace.

Returns:

Parsed double[]

preRender

public void preRender(ColladaTraversalContext tc,
                      DrawContext dc)

Pre-Render this element.

Specified by:

preRender in interface ColladaRenderable

Parameters:

tc - the current COLLADA traversal context.

dc - the current draw context.

render

public void render(ColladaTraversalContext tc,
                   DrawContext dc)

Render this element.

Specified by:

render in interface ColladaRenderable

Parameters:

tc - the current COLLADA traversal context.

dc - the current draw context.

setField

public void setField(String keyName,
                     Object value)

Overrides:

setField in class AbstractXMLEventParser
