ext.int.mesh

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 = "ast3d",
  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 NULL 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 sphere inscribed into the mesh

method

character: select "a" or "c"

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
