cutMesh: crop triangular surface meshes

In zarquon42b/mesheR: Meshing Operations on Triangular Meshes

crop triangular surface meshes

Description

crop a surface mesh interactively.

Usage

cutMesh(
  mesh,
  visible = TRUE,
  keep.selected = TRUE,
  col = 3,
  add = FALSE,
  render = c("shade", "wire"),
  offset = 0.001,
  ...
)

Arguments

mesh	triangular mesh of class "mesh3d"
visible	select only vertices visible (from the present point of view)
keep.selected	logical: determines if the selected vertices or their complement are deleted.
col	color to render the mesh.
add	logical: add the surface to an existing window.
render	character: how to render the surface. Possible values are "shade" or "wire".
offset	initial offset to move vertex slightly away from the surface. 1e-3 seems to be a good threshold for objects from the macroscopical world.
...	additional arguments passed to the rendering functions shade3d and wire3d from package "rgl".

Details

select vertices or trim a triangular mesh by selecting a subset - either restricted to visible from the current point of view or by rectangular region. Visibility is determined by the fact that the vector from the viewpoint to the selected vertex does not intersect the mesh.

Value

selectVertex returns the indices of the selected vertices.

cutMesh returns the trimmed mesh.
