geomorph (version 1.1-6)

plotspec: Plot 3D specimen, fixed landmarks and surface semilandmarks.

Description

A function to plot three dimensional (3D) specimen along with its landmarks.

Usage

plotspec(spec, digitspec, fixed, ptsize = 1)

Arguments

spec

Name of surface file, as either an object of class shape3d/mesh3d, or matrix of three-dimensional vertex coordinates.

digitspec

Name of data matrix containing three-dimensional fixed and/or surface sliding coordinates.

fixed

numeric: The number of fixed template landmarks

ptsize

numeric: Size to plot the mesh points (vertices), e.g. 0.1 for dense meshes, 3 for sparse meshes

Details

Function to plot 3D specimens along with their digitized "fixed" landmarks and semilandmarks "surface sliders" and "curve sliders". If specimen is a 3D surface (ply file), mesh is plotted.

Examples

data(scallopPLY)
ply <- scallopPLY$ply
digitdat <- scallopPLY$coords
plotspec(spec=ply,digitspec=digitdat,fixed=16)
