ext.int.mesh: ext.int.mesh

In Arothron/Arothron: Geometric Morphometrics Analyses

Description

This function finds the vertices visible from a set of points of view

Usage

ext.int.mesh(mesh, views = 20, dist.sphere = 3, param1 = 2.5,
  param2 = 10, default = TRUE, import_pov, matrix_pov, expand = 1,
  scale.factor, method = "calse", start.points = 250,
  num.cores = NULL)

Arguments

mesh	object of class mesh3d
views	numeric: number of points of view
dist.sphere	numeric: scale factor. This parameter the distance betweem the barycenter of the mesh and the radius of the sphere used to define set of points of view
param1	numeric: first parameter for spherical flipping (usually ranged from 0.5 to 5, try!)
param2	numeric second paramter for spherical flipping (don't change it!)
default	logical: if TRUE the points of views are defined automatically, if FALSE define the matrix_pov
import_pov	logical: if TRUE the operator needs to specify in the arguent matrix_pov the matrix of the points of view to be used. If NULL (and default argument set on TRUE) the points of view are automatically specified. if NULL (and default argument set on FALSE) an interactive 3D plot for the definition of the points of view is returned
matrix_pov	matrix: external set of points of view
expand	numeric: scale factor for the grid for the interactive 3D plot
scale.factor	numeric: scale factor for
method	character: select "a" or "c". Currently only "calse" method is supported
start.points	numeric: number of POVs available
num.cores	numeric: number of cores

Value

position numeric: a vector with vertex number nearest the landmark set
