dot-cluster_patch: Assign patch coordinates to one of two surfaces

In cornelmpop/Lithics3D: A toolbox for 3D analysis of archaeological lithics

Assign patch coordinates to one of two surfaces

Description

Classifies 3D coordinates of mesh vertices into one of two groups representing intersecting surfaces.

Usage

.cluster_patch(coords, normals, rad, lambda)

Arguments

coords	An Nx3 numeric matrix-like object where each row represents the x, y, and z coordinates of a mesh vertex.
normals	An Nx3 numeric matrix-like object where each row represents the x, y, and z components of a normal vector corresponding to each vertex in coords.
rad	A positive numeric value representing the radius that influences the classification.
lambda	A positive numeric value used as a scaling factor in the classification calculation.

Details

This is a translation of c++ code from the Meshlab Virtual Goniometer plugin developed by the AMAAZE consortium

Value

A numeric vector where each element corresponds to a point in coords and indicates the classification of that point into one of two groups (1 or 2).

Examples

## Not run: 
coords <- matrix(rnorm(300), ncol = 3)
normals <- matrix(rnorm(300), ncol = 3)
rad <- 1
lambda <- 0.5
classification <- Lithics3D:::.cluster_patch(coords, normals, rad, lambda)
print(classification)
