Constructor Detail

ColladaVisualScene

public ColladaVisualScene(String ns)

Construct an instance.

Parameters:

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

Method Detail

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.

getNodes

public List<ColladaNode> getNodes()

Indicates the nodes in the scene.

Returns:

List of nodes. May return an empty list, but never returns null.

preRender

public void preRender(ColladaTraversalContext tc,
                      DrawContext dc)

Pre-Render this element. Renders all nodes in this scene.

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. Renders all nodes in this scene.

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
