Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class CompositePropertyBase

Returns:

static information for all exported properties

getSigma

public double getSigma()

setSigma

public void setSigma(double sigma)

scaleDistance

public void scaleDistance(double s)

Description copied from interface: ScalableUnits

Scales all distance coordinates.

Specified by:

scaleDistance in interface ScalableUnits

Overrides:

scaleDistance in class SkinWeightingFunction

Parameters:

s - scaling factor

computeWeights

public void computeWeights(double[] weights,
                           Point3d pos,
                           SkinMeshBody.NearestPoint[] nearestPnts)

Computes skinning connection weights for a point located at pos, given information about the nearest points on each of the master bodies.

The weights are returned in weights. There is one weight for each master bodies, and so weights and nearestPnts have the same length.

Specified by:

computeWeights in class SkinWeightingFunction

Parameters:

weights - returns the computed weights

pos - position of the point to be skinned

nearestPnts - nearest point information for each of the master bodies
