Constructor Details

OGLTriangleSet2D

public OGLTriangleSet2D()

Construct a new point set instance that contains no child nodes.

OGLTriangleSet2D

public OGLTriangleSet2D(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

getGeometry

public org.j3d.aviatrix3d.Geometry getGeometry()

Description copied from interface: OGLGeometryNodeType

Returns a OGL Geometry node that represents this piece of geometry. If no geometry is available, then return null.

Specified by:

getGeometry in interface OGLGeometryNodeType

Returns:

The geometry needed to represent this object

setTextureCount

public void setTextureCount(int count)

Set the number of textures that were found on the accompanying Appearance node. Used to set the number of texture coordinates that need to be passed in to the renderer when no explicit texture coordinates were given.

Specified by:

setTextureCount in interface VRMLGeometryNodeType

Overrides:

setTextureCount in class BaseTriangleSet2D

Parameters:

count - The number of texture coordinate sets to add

getNumSets

public int getNumSets()

Get the number of texture coordinate sets contained by this node

Specified by:

getNumSets in interface VRMLGeometryNodeType

Overrides:

getNumSets in class BaseTriangleSet2D

Returns:

the number of texture coordinate sets

getTexCoordGenMode

public String getTexCoordGenMode(int setNum)

Get the texture coordinate generation mode. NULL is returned if the texture coordinates are not generated.

Specified by:

getTexCoordGenMode in interface VRMLGeometryNodeType

Overrides:

getTexCoordGenMode in class BaseTriangleSet2D

Parameters:

setNum - The set which this tex gen mode refers

Returns:

The mode or NULL

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the Java3D scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation.

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.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class AbstractNode

updateNodeBoundsChanges

public void updateNodeBoundsChanges(Object src)

Notification that its safe to update the node now with any operations that could potentially effect the node's bounds.

Specified by:

updateNodeBoundsChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

updateNodeDataChanges

public void updateNodeDataChanges(Object src)

Notification that its safe to update the node now with any operations that only change the node's properties, but do not change the bounds.

Specified by:

updateNodeDataChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

setVertices

protected void setVertices(float[] coords,
 int numValid)

Set the value of the vertices field.

Overrides:

setVertices in class BaseTriangleSet2D

Parameters:

coords - The list of coordinates to use

numValid - The number of valid values to copy from the array
