vcg_uniform_remesh: Sample a surface mesh uniformly

In ravetools: Signal and Image Processing Toolbox for Analyzing Intracranial Electroencephalography Data

Sample a surface mesh uniformly

Description

Sample a surface mesh uniformly

Usage

vcg_uniform_remesh(
  x,
  voxel_size = NULL,
  offset = 0,
  discretize = FALSE,
  multi_sample = FALSE,
  absolute_distance = FALSE,
  merge_clost = FALSE,
  verbose = TRUE
)

Arguments

x	surface
voxel_size	'voxel' size for space 'discretization'
offset	offset position shift of the new surface from the input
discretize	whether to use step function (TRUE) instead of linear interpolation (FALSE) to calculate the position of the intersected edge of the marching cube; default is FALSE
multi_sample	whether to calculate multiple samples for more accurate results (at the expense of more computing time) to remove artifacts; default is FALSE
absolute_distance	whether an unsigned distance field should be computed. When set to TRUE, non-zero offsets is to be set, and double-surfaces will be built around the original surface, like a sandwich.
merge_clost	whether to merge close vertices; default is TRUE
verbose	whether to verbose the progress; default is TRUE

Value

A triangular mesh of class 'mesh3d'

Examples

sphere <- vcg_sphere()
mesh <- vcg_uniform_remesh(sphere, voxel_size = 0.45)

if(is_not_cran()) {

rgl_view({

  rgl_call("mfrow3d", 1, 2)

  rgl_call("title3d", "Input")
  rgl_call("wire3d", sphere, col = 2)
  rgl_call("next3d")

  rgl_call("title3d", "Re-meshed to 0.1mm edge distance")
  rgl_call("wire3d", mesh, col = 3)
})

}
