public class OGLTriangleStripSet
extends BaseTriangleStripSet
implements OGLGeometryNodeType, org.j3d.aviatrix3d.NodeUpdateListener

OpenGL implementation of an TriangleStripSet.

The point set directly maps to Aviatrix3D's TriangleStripArray class. When the coordinates change to a different length than the current set, it will notify the geometry listener to fetch the new information.

If the VRML file did not provide a Coordinate node, then this class will not present any geometry from the getGeometry() or getSceneGraphObject() calls. If the user later specifies the renderety through an event, the listener(s) will be notified.

In this implementation, if the length of the color array is shorter that the length of the coordinate array, colors will be ignored.

Constructor Details

OGLTriangleStripSet

public OGLTriangleStripSet()

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

OGLTriangleStripSet

public OGLTriangleStripSet(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:
