PLYReader

Source (.js)Source (.d.ts)

Introduction

vtkPLYReader is a source object that reads polygonal data in Stanford University PLY file format (see http://graphics.stanford.edu/data/3Dscanrep). It requires that the elements "vertex" and "face" are defined. The "vertex" element must have the properties "x", "y", and "z". The "face" element must have the property "vertex_indices" defined. Optionally, if the "face" element has the properties "intensity" and/or the triplet "red", "green", "blue", and optionally "alpha"; these are read and added as scalars to the output data. If the "face" element has the property "texcoord" a new TCoords point array is created and points are duplicated if they have 2 or more different texture coordinates.
