ext.int.mesh: 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
)

Value

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

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
