Description

visualises the vertex normals of a triangular surface mesh of class mesh3d. If no normals are contained, they are computed.

Usage

plotNormals(x, length = 1, lwd = 1, col = 1, ...)

Arguments

x

object of class "mesh3d"

length

either a single numeric value or a numeric vector defining per-normals lenght (default is 1)

lwd

width of the normals

col

color of the normals

...
