Class VGLNode

java.lang.Object
  hmi.graphics.opengl.scenegraph.VGLNode

All Implemented Interfaces:

GLRenderObject

Direct Known Subclasses:

PhysicalHumanVGLNode, SimpleLight, SimpleLight

public class VGLNode
extends Object
implements GLRenderObject

A VGL node combines a VJoint (tree) with a GLRenderList. The GLRenderList objects will usually link to the global transform matrix of the VJoint.

Field Summary

private GLRenderObject	marker
private VJoint	root The VJoint root determines the transformation for this VGLNode.
private GLRenderList	shapeList The GLRenderList shapeList specifies GLRenderObjects to be rendered.

Constructor Summary

VGLNode(String name)
Creates a new VGLNode, specified name and capacity 1.

VGLNode(String name, int capacity)
Creates a VGLNode with allocated root, with specified name, and with allocated shapeList, with specified capacity.

VGLNode(VJoint root, GLRenderList shapeList)
Creates a VGLNode with specified root and shapeList.

Method Summary

void	addChild(VGLNode childNode) Adds the root of the childNode as a VJoint child, and appends all shapeList elements from the childNode to the shapeList of this VGLNode.
void	addGLShape(GLShape glShape) Adds some GLShape, and links it to the root of this VGLNode
void	addMarker()
void	addMarker(GLRenderObject marker)
GLRenderList	getGLShapeList()
VJoint	getRoot()
void	glInit(GLRenderContext gl) OpenGL initialization.
void	glRender(GLRenderContext gl) OpenGL rendering.
void	prependGLShape(GLShape glShape)
String	toString()

Field Detail

root

private VJoint root

The VJoint root determines the transformation for this VGLNode.

shapeList

private GLRenderList shapeList

The GLRenderList shapeList specifies GLRenderObjects to be rendered.

marker

private GLRenderObject marker

Constructor Detail

VGLNode

public VGLNode(String name)

Creates a new VGLNode, specified name and capacity 1.

VGLNode

public VGLNode(String name,
               int capacity)

Creates a VGLNode with allocated root, with specified name, and with allocated shapeList, with specified capacity.

VGLNode

public VGLNode(VJoint root,
               GLRenderList shapeList)

Creates a VGLNode with specified root and shapeList. It is assumed here that the list elements are linked to the appropriate VJoint already, which need not be the root of this VGLNode.

addGLShape

public void addGLShape(GLShape glShape)

Adds some GLShape, and links it to the root of this VGLNode

addChild

public void addChild(VGLNode childNode)

Adds the root of the childNode as a VJoint child, and appends all shapeList elements from the childNode to the shapeList of this VGLNode.

addMarker
