retroDeformMesh: symmetrize a triangular mesh

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

symmetrize a triangular mesh

Description

symmetrize a triangular mesh

Usage

retroDeformMesh(
  mesh,
  mat,
  pairedLM,
  hmult = 5,
  alpha = 0.01,
  rot = TRUE,
  lambda = 1e-08,
  threads = 0
)

Arguments

mesh	triangular mesh of class mesh3d
mat	matrix with bilateral landmarks
pairedLM	2-column integer matrix with the 1st columns containing row indices of left side landmarks and 2nd column the right hand landmarks
hmult	damping factor for calculating local weights which is calculated as humult times the average squared distance between a landmark and its closest neighbor (on each side).
alpha	factor controlling spacing along x-axis
rot	logical: if TRUE the deformed landmarks are rotated back onto the original ones
lambda	control parameter passed to tps3d
threads	integer: number of threads to use for TPS deform

Details

this function performs retroDeform3d and deforms the mesh accordingly using the function tps3d.

Value

mesh	symmetrized mesh
landmarks	a list containing the deformed and original landmarks
