shootflow: Apply deformetrica registration to a set of 3D points...

In alexanderbates/deformetricar: R wrapper for elements of the Deformetrica registration tool

Description

Apply a Deformetrica deformation using calculated momentum vectors and control points (in files MOM_final.txt and CP_final.txt respectively), by calling the executable ShootAndFlow3. This requires installation of Deformetrica version 2.1 or later (preferably in Applications).

Usage

shootflow(x, ...)

## S3 method for class 'neuron'
shootflow(x, ...)

## S3 method for class 'neuronlist'
shootflow(x, ...)

## Default S3 method:
shootflow(x, regdir = system.file("extdata/reg_output/",
  package = "deformetricar"), kernel.width = 5,
  object.type = c("PointCloud", "OrientedPolyLine", "NonOrientedPolyLine",
  "OrientedSurfaceMesh", "NonOrientedSurfaceMesh"), verbose = FALSE, ...)

Arguments

x	object to be transformed (for shootflow.default method an Nx3 matrix of 3D coordinates)
...	additional arguments eventually passed by methods shootflow.default
regdir	Path to directory containing deformetrica registration
kernel.width	the width of the deformation kernel. The larger the more rigid the deformation. The smaller, the more local variations of the space is allowed.
object.type	type of object to be deformed. PointCloud, OrientedPolyLine, NonOrientedPolyLine, OrientedSurfaceMesh and NonOrientedSurfaceMesh
verbose	Whether to show status messages from ShootAndFlow3 command line tool
data.sigma	matching factor. The lower ir is, the tighter the matching.

Value

matrix of the same dimensions as x
