plotNormals: plots the normals of a triangular surface mesh.

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

plots the normals of a triangular surface mesh.

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
...	addtional parameters, currently not in use.
