DistanceImage: Create a (signed) distance image from surface mesh

In zarquon42b/RANTs: Playing with ANTs(R)

Description

Create a (signed) distance image from surface mesh

Usage

DistanceImage(x, spacing = rep(1, 3), margin = 0.05, sign = TRUE,
  k = 1, IJK2RAS = diag(c(-1, -1, 1, 1)), cores = 2, useMP = TRUE,
  maxind = ifelse(useMP, 1e+06, 1e+05))

Arguments

x	surface mesh
spacing	spacing of grid
margin	percentage to add to grid
sign	logical: if TRUE signed distances are computed
k	k- closest faces to consider during closest point search
IJK2RAS	transformation between physical and image space
cores	integer: amount of cores used in parallel execution (be careful, as the process gets forked and then uses cores times as much RAM).
useMP	logical: if TRUE the parallel computation will be during kdtree search, otherwise the mclapply is used.
maxind	integer: maximum amount of grid points to evaluate at once (for memory reasons)

Value

returns a distance image of class antsImage
