colour_mesh: Colourize a mesh

In Mouse-Imaging-Centre/RMINC: Statistical Tools for Medical Imaging NetCDF (MINC) Files

Colourize a mesh

Description

Add colour information to your mesh, either from a vertex atlas like AAL or from a statistic/measurement map like those produced by CIVET

Usage

colour_mesh(
  mesh,
  colour_map,
  colour_range = NULL,
  colour_default = "grey",
  symmetric = NULL,
  labels = FALSE,
  palette = heat.colors(255)
)

Arguments

mesh	mesh3d object ideally produced by create_mesh
colour_map	either a vector with a label/measure/statistic for every vertex or a character file path pointing to a file with such a vector in a rowwise format.
colour_range	a two element numeric vector indicating the min and max values of allowable labels/measures/statistics to be includedon the surface
colour_default	The colour given to vertices excluded by colour_range
symmetric	Whether to have a positive and negative colour scale (not yet implemented)
labels	Whether or not the colour_map is a set of discrete labels
palette	A palette, AKA look-up-table, providing a linear colour scale for the colours in colour_map

Value

an obj_mesh object descended from mesh3d, with added colour information and an additional legend element to be used in building a colour bar
