mergeVertices {rgl} | R Documentation |
A mesh object can have the same vertex listed twice. Each copy is
allowed to have separate normals, texture coordinates, and color.
However, it is more efficient to have just a single copy if those
differences aren't needed. For automatic smoothing using
addNormals
, triangles and quads need to share vertices.
This function merges identical (or similar) vertices to achieve this.
mergeVertices(mesh, notEqual = NULL, attribute = "vertices", tolerance = sqrt(.Machine$double.eps))

objects containing a lot of duplication.
