would need to figure out domain of input points (defined by a single template?)
also would be best to optimise the points (spreading them out, selecting a subset whose removal has least impact on error)
there are also schemes for optimising fwd/inverse consistency for tps

sample_points_in_surf <- function(x, n){
  x=as.mesh3d(x)
  bb=boundingbox(x)
  mm=mapply(runif, min=bb[1,], max=bb[2,], n = n)
  colnames(mm)=c("X","Y","Z")
  data.frame(mm, inside=pointsinside(mm,x))
}
