This functions aims to translate two meshes to remove an intersection

Description

This functions aims to translate two meshes to remove an intersection. This is done based on signed distance

Usage

removeIntersect(
  reference,
  target,
  stepsize = 0.2,
  maxit = 100,
  tol = 1,
  outside = TRUE,
  gradthresh = -Inf,
  gradn = Inf,
  realign = FALSE,
  minalign = 5,
  alignthresh = 0.5,
  visualize = FALSE,
  silent = FALSE,
  threads = 0,
  alpha = 1
)

Arguments

reference	matrix or mesh
target	mesh of class mesh3d
stepsize	regularize the actual displacement
maxit	maximum iterations
tol	positive number: stop if intersection is less than tol
outside	logical: if TRUE the reference will be placed outside of the target. Inside otherwise
gradthresh	numerical: (abs) gradient threshold to determine convergence
gradn	integer: number of steps to include in computing gradient
realign	logical: if TRUE, reference will be aligned by the points closest outside/inside of the target surface.
alignthresh	threshold which points to consider for realignment. For alignthresh=.5, all coordinates within .5 mm outside/inside of the targtet will be used to realign the shape.
visualize	logical: if TRUE watch the approximation
silent	logical: suppress messages
threads	number of threads to use for closest point search (0=auto)
alpha	value with 0 <= alpha <=1 to render surface opacity of the target mesh.

Details

This is a quite simple attempt to remove an intersection after the alignment of two meshes. This is achieved by translating reference along the average difference vectors of all vertices
