Field Detail

skinGroup

protected Group skinGroup

Group for containing the skin Shape nodes

bufferGeometry

protected ArrayList<Geometry> bufferGeometry

Geometry instances that implement BufferGeometry

vertexGeometry

protected ArrayList<Geometry> vertexGeometry

Geometry instances that implement VertexGeometry

skin

protected Node[] skin

Collection of nodes that is the skin

numSkin

protected int numSkin

The number of valid items in the skin list

coordsArray

protected float[] coordsArray

An array for coordinates to be splatted to if the contained geometry is an instance of VertexGeometry.

normalsArray

protected float[] normalsArray

An array for coordinates to be splatted to if the contained geometry is an instance of VertexGeometry.

coordsBuffer

protected FloatBuffer coordsBuffer

An array for coordinates to be splatted to if the contained geometry is an instance of VertexGeometry.

normalsBuffer

protected FloatBuffer normalsBuffer

An array for coordinates to be splatted to if the contained geometry is an instance of VertexGeometry.

dirtyCoordinates

protected boolean[] dirtyCoordinates

A list of per-vertex flags to indicate which ones have changed since the last update. This is so that we don't unneccesarily modify the coordinates of the system that haven't changed due to the skeleton not changing in that area. When we clear the output coordinate/normal array, we only clear those that have marked their flag here.

Method Detail

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 NodeUpdateListener

Overrides:

updateNodeBoundsChanges in class AVHumanoid

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 NodeUpdateListener

Overrides:

updateNodeDataChanges in class AVHumanoid

Parameters:

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

setSkinCoord

public void setSkinCoord(float[] val,
                         int numElements)

Set a new value for the skinCoord of this joint. If the array is null or not long enough an exception is generated. The array must be at least a multiple of 3 units long.

Overrides:

setSkinCoord in class org.j3d.geom.hanim.HAnimHumanoid

Parameters:

val - The new skinCoord value to use

numElements - The number of 3d-vectors in the array

Throws:

IllegalArgumentException - The array is null or not long enough.

setSkinNormal

public void setSkinNormal(float[] val,
                          int numElements)

Set a new value for the skinNormal of this joint. If the array is null or not long enough an exception is generated. The array must be at least a multiple of 3 units long.

Overrides:

setSkinNormal in class org.j3d.geom.hanim.HAnimHumanoid

Parameters:

val - The new skinNormal value to use

numElements - The number of 3d-vectors in the array

Throws:

IllegalArgumentException - The array is null or not long enough.

setSkeleton

public void setSkeleton(org.j3d.geom.hanim.HAnimObject[] kids,
                        int numValid)

Replace the existing viewpoints with the new set of viewpoints.

Overrides:

setSkeleton in class AVHumanoid

Parameters:

kids - The collection of child objects to now use

numValid - The number kids to copy from the given array

updateSkeleton

public void updateSkeleton()

All the skeletal changes are in for this frame, so update the matrix values now. If nothing has changed, don't bother doing any calculations and return immediately.

Overrides:

updateSkeleton in class AVHumanoid

setSkin

public void setSkin(Node[] skins,
                    int numSkins)

Set the list of geometry that should be used by this humanoid. These are not directly inserted into the scene graph, but are used for reference to generate our own internal model. When skinned mesh animation takes place, the coordinates are automatically fed from this humanoid to the appropriate geometry. For best performance, the geometry should make use of BufferGeometry class.

Specified by:

setSkin in class AVHumanoid

Parameters:

skins - List of representative shapes to use

numSkins - The number of valid items to use from the skins array

getUpdatedSkinCoords

public abstract Object getUpdatedSkinCoords()

Get the internal representation of the updated mesh skin coordinates.

Returns:

An object that is either a float[] or FloatBuffer, depending on the internal implementation used.

getUpdatedSkinNormals

public abstract Object getUpdatedSkinNormals()

Get the internal representation of the updated mesh skin normals.

Returns:

An object that is either a float[] or FloatBuffer, depending on the internal implementation used.
