public DefaultSkinModel()

Creates a new instance

Method Detail

setBindShapeMatrix

public void setBindShapeMatrix(float[] bindShapeMatrix)

Set the bind shape matrix

Parameters:

bindShapeMatrix - The bind shape matrix. A copy of this array will be stored. If it is null, a new array will be created, which represents the identity matrix.

addJoint

public void addJoint(NodeModel joint)

Add the given joint

Parameters:

joint - The joint

setSkeleton

public void setSkeleton(NodeModel skeleton)

Set the skeleton root node

Parameters:

skeleton - The skeleton root node

setInverseBindMatrices

public void setInverseBindMatrices(AccessorModel inverseBindMatrices)

Set the inverse bind matrices

Parameters:

inverseBindMatrices - The inverse bind matrices

getBindShapeMatrix

public float[] getBindShapeMatrix(float[] result)

Description copied from interface: SkinModel

Provides the bind shape matrix of the skin.

The result will be written to the given array, as a 4x4 matrix in column major order. If the given array is null or does not have a length of 16, then a new array with length 16 will be created and returned.

Specified by:

getBindShapeMatrix in interface SkinModel

Parameters:

result - The result array

Returns:

The result array

getJoints

public java.util.List<NodeModel> getJoints()

Description copied from interface: SkinModel

Returns an unmodifiable list containing the joint nodes of the skeleton

Specified by:

getJoints in interface SkinModel

Returns:

The joint nodes

getSkeleton

public NodeModel getSkeleton()

Description copied from interface: SkinModel

Returns the skeleton root node. If the return value is null, then joint transforms refer to the scene root.

Specified by:

getSkeleton in interface SkinModel

Returns:

The skeleton node

getInverseBindMatrices

public AccessorModel getInverseBindMatrices()

Description copied from interface: SkinModel

Returns the AccessorModel that provides the data for the inverse bind matrices, one for each joint

Specified by:

getInverseBindMatrices in interface SkinModel

Returns:

The inverse bind matrices accessor

getInverseBindMatrix

public float[] getInverseBindMatrix(int index,
                                    float[] result)

Description copied from interface: SkinModel

Convenience function to obtain the inverse bind matrix for the joint with the given index.

The result will be written to the given array, as a 4x4 matrix in column major order. If the given array is null or does not have a length of 16, then a new array with length 16 will be created and returned.

Specified by:

getInverseBindMatrix in interface SkinModel

Parameters:

index - The index of the joint

result - The result array

Returns:

The result array
