IllegalArgumentException - if the @code{plane} argument is null

Method Details

measureWeightedSymmetry

public void measureWeightedSymmetry(SymmetryVisitorRobustMesh.ProcessedCloud cache,
 UniformGrid3d<MeshPoint> grid,
 double alpha)

Symmetry measurement based on the similarity of Gaussian curvatures and the symmetry of normal vectors, in addition to Wendland’s similarity function.The plane is normalized and numAvg set to zero!

Parameters:

cache - Precomputed values, including downsampled points

grid - The same cloud stored in the uniform grid

alpha - the average distance between vertices and their centroid

getNormalVectorsWeight

public static double getNormalVectorsWeight(javax.vecmath.Vector3d rv1,
 javax.vecmath.Vector3d v2)

Returns the symmetry of normal vectors

Parameters:

rv1 - A normal vector already reflected over this plane

v2 - A second normal vector for comparison

Returns:

the symmetry of the given normal vectors
