read.ply2: Read mesh data (vertices and faces) from .ply files

In ckenaley/geomorphcompanion: This package prvide help with the geomorph package

Description

Read .ply files to be used for digitizing landmark coordinates.

Usage

read.ply2(file, ShowSpecimen = FALSE)

Arguments

file	character, a path to an ASCII .ply file
ShowSpecimen	logical,should the ply file should be displayed

Details

Function reads three-dimensional surface data in the form of a single .ply file (Polygon File Format; ASCII format only, from 3D scanners or from .ply rendered from STL files produced by surface renderings of computed tomography data. The function opens the ply file and plots the mesh in a local shiny app if ShowSpecimen=TRUE.

Value

A list with the following components:

#'

• "x","y", and "z", the x, y, and z coordinats of the mesh vertices

• "mesh", mesh3d object whose name describes the number of vertices and triangles.

• "zmean", the mean z position for each triangle (used for face coloring)

• "facecolor", a face color according to colour_ramp palette "RdBu"
