#' Draw a mesh as surfaces in 3D
#'
#' Draw surfaces with rgl from any [shape3d][rgl::tmesh3d] classed object. Produces
#' a 3D surface plot from a mesh-alike object.
#'
#' Objects that are not explicitly surfaces will be triangulated in order to
#' produce the mesh. Whether this is a good idea or not is an open question, and
#' some conversions will fail due to "extra" attributes like z or time stored on
#' vertices. Polygons are only implicit surfaces but these are usually
#' unproblematic to triangulate so this is done.
