vcg_subdivision: Sub-divide (up-sample) a triangular mesh

Description

Up-sample a triangular mesh by adding a vertex at each edge or face center.

Usage

vcg_subdivision(mesh, method = c("edge", "barycenter"))

Value

An object of class "mesh3d"

Arguments

mesh

triangular mesh stored as object of class 'mesh3d'.

method

either 'edge' (default) to add new mid-point vertices to edge, or 'barycenter' to add new vertices at face 'Bary' centers.

Examples

mesh <- plane_geometry()

# default
mesh_edge <- vcg_subdivision(mesh, "edge")

# barycenter
mesh_face <- vcg_subdivision(mesh, "barycenter")

if(is_not_cran()) {

  rgl_view({
    rgl_call("wire3d", mesh, col = 1)
    rgl_call("wire3d", mesh_edge, col = 2)
    rgl_call("wire3d", mesh_face, col = 3)
  })
