placeDowels: Place Dowels representing tissue depth on a skull

In zarquon42b/mesheR: Meshing Operations on Triangular Meshes

Place Dowels representing tissue depth on a skull

Description

Place Dowels representing tissue depth on a skull by using predefined tissue-values

Usage

placeDowels(
  lm,
  mesh,
  ldowel,
  render = TRUE,
  col = 1,
  radius = 1,
  meshcol = 3,
  fine = 50,
  smooth = TRUE,
  dowelcol = NULL
)

Arguments

lm	k x 3landmarks representing dowel locations
mesh	triangular mesh (object of class 'mesh3d')
ldowel	vector of length k giving a length for each dowel
render	logical: if TRUE, the result will be rendered in an rgl window
col	color of the dowels
radius	numeric: diameter of dowels
meshcol	mesh color
fine	integer: amount of vertices to generate the cylinders representing tissue thickness.
smooth	logical: use smoothed normals for dowel orientation

Details

For orientation of the dowels, the (angle weighted) normal vectors of the surface is used.

Value

an invisible list with

dowels	a list containing the meshes for all dowels
endpoints	a matrix containing the coordinates of the dowels endpoints
