public class LineArray
extends VertexGeometry

An OpenGL LineArray.

Lines cannot be picked in the traditional manner using geometry-based picking. The only way to pick them is based on their bounds.

Constructor Detail

LineArray

public LineArray()
Constructs a LineArray with default values.

Method Detail

setValidVertexCount

public void setValidVertexCount(int count)
                         throws java.lang.IllegalStateException,
                                java.lang.IllegalArgumentException,
                                InvalidWriteTimingException
Set the number of vertices to the new number.

In a live scene graph, can only be called during the bounds changed callback.

Overrides:
setValidVertexCount in class VertexGeometry
Parameters:
count - The new number, must be >= 0
Throws:
java.lang.IllegalStateException - This call was not made during the update callback if the node is live
java.lang.IllegalArgumentException - The number is negative
InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener callback method

setVertices

public void setVertices(int type,
                        float[] vertices,
                        int numValid)
                 throws java.lang.IllegalStateException,
                        java.lang.IllegalArgumentException,
                        InvalidWriteTimingException
Set the vertex array reference to the new array. The number of valid items is taken from the second parameter. This replaces the existing vertex list array reference with the new reference.

In a live scene graph, can only be called during the bounds changed callback.

Overrides:
setVertices in class VertexGeometry
Parameters:
type - The number of dimensions to the coordinates - 2D, 3D or 4D
vertices - The new array reference to use for vertex information
numValid - The number of valid values to use in the array
Throws:
java.lang.IllegalStateException - This call was not made during the update callback if the node is live
java.lang.IllegalArgumentException - The number is negative
InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener callback method

render

public void render(net.java.games.jogl.GL gl,
                   net.java.games.jogl.GLU glu)
Issue ogl commands needed for this renderable object.

Parameters:
gl - The gl context to draw with
glu - The utility context to draw with

postRender

public void postRender(net.java.games.jogl.GL gl,
                       net.java.games.jogl.GLU glu)
Restore all openGL state.

Parameters:
gl - The gl context to draw with
glu - The utility context to draw with
