Get the number of texture coordinate sets contained by this node

Specified by:

If there are no components then a zero length array will be returned.

Specified by:

getComponents in interface VRMLComponentGeometryNodeType

Returns:

VRMLNodeType[] The components

setComponents

public void setComponents(VRMLNodeType[] comps)
                   throws InvalidFieldValueException

Set the components the compose a geometry object. To clear all the components, pass a null parameter.

Specified by:

comps - An array of geometric properties

Throws:

InvalidFieldValueException - The node is not a known or supported field for this node

                  throws InvalidFieldValueException

Set a component that composes part of a geometry object.

Specified by:

comp - A geometric property

Throws:

InvalidFieldValueException - The node is not a known or supported field for this node

hasColorPerVertex

Check to see if the colors are per vertex or per face.

Specified by:

hasColorPerVertex in interface VRMLComponentGeometryNodeType

Returns:

true The colors are per vertex

hasNormalPerVertex

public boolean hasNormalPerVertex()

Check to see if the normals are per vertex or per face.

Specified by:

hasNormalPerVertex in interface VRMLComponentGeometryNodeType

Returns:

true The normals are per vertex

requiresUnlitColor

public boolean requiresUnlitColor()

Check to see if this geometry implementation type requires unlit color values to be set. For the most part this will always return false, but some will need it (points and lines). This value should be constant for the geometry regardless of whether a Color component has been provided or not. It is up to the implementation to decide when to pass these values on to the underlying rendering structures or not.

The default implementation returns false. Override if different behaviour is needed.

Specified by:

requiresUnlitColor in interface VRMLComponentGeometryNodeType

Returns:

true if we need unlit colour information

setUnlitColor

public void setUnlitColor(float[] color)

Set the local colour override for this geometry. Typically used to set the emissiveColor from the Material node into the geometry for the line and point-type geometries which are unlit in the X3D/VRML model.

The default implementation does nothing. Override to do something useful.

Specified by:

setUnlitColor in interface VRMLComponentGeometryNodeType

Parameters:

color - The colour value to use

getPrimaryType

public int getPrimaryType()

Get the primary type of this node. Replaces the instanceof mechanism for use in switch statements.

Specified by:

getPrimaryType in interface VRMLNode

The primary type

setupFinished

public void setupFinished()

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

getFieldValue

public VRMLFieldData getFieldValue(int index)
                            throws InvalidFieldException

Get the value of a field. If the field is a primitive type, it will return a class representing the value. For arrays or nodes it will return the instance directly.

Specified by:

getFieldValue in interface VRMLNodeType

Overrides:

getFieldValue in class AbstractNode

Parameters:

index - The index of the field to change.

Returns:

The class representing the field value

Throws:

InvalidFieldException - The field index is not known

sendRoute

public void sendRoute(double time,
 int srcIndex,
 VRMLNodeType destNode,
 int destIndex)

Send a routed value from this node to the given destination node. The route should use the appropriate setValue() method of the destination node. It should not attempt to cast the node up to a higher level. Routing should also follow the standard rules for the loop breaking and other appropriate rules for the specification.

Specified by:

sendRoute in interface VRMLNodeType

Overrides:

sendRoute in class AbstractNode

Parameters:

time - The time that this route occurred (not necessarily epoch time. Should be treated as a relative value only)

srcIndex - The index of the field in this node that the value should be sent from
