Method Detail

setIndex

public void setIndex(int idx)

getIndex

public int getIndex()

getFrame

public Frame getFrame()

Returns the Frame component itself.

setFrame

public void setFrame(Frame frame)

getBasePose

public RigidTransform3d getBasePose()

Returns the current base pose for this frame. Skin displacements are computed with respect to the base pose.

setBasePose

public void setBasePose(RigidTransform3d T)

Sets the base pose for this frame.

getDeltaPose

public RigidTransform3d getDeltaPose()

Returns the displacement from the base pose to the Frame's current pose. If the base pose is XBW, and the current pose is TFW, then this is computed as

  TFW * inv(XBW)
 

The computation is done in

getBlendQuaternion

public DualQuaternion getBlendQuaternion()

Returns the DualQuaternion representation of the transform returned by getDeltaPose().

getMesh

public PolygonalMesh getMesh()

Description copied from class: SkinMeshBody.BodyInfo

Returns the PolygonalMesh, if any, associated with this body.

Specified by:

getMesh in class SkinMeshBody.BodyInfo

updatePosState

public void updatePosState()

Computes the quantities returned by getDeltaPose(), and, for non-linear blending, getBlendQuaternion(). This should be called, before these quantities are used, whenever the Frame's pose changes.

updateDualQuaternion

public void updateDualQuaternion()
