Class WavefrontReader

java.lang.Object

maspack.geometry.io.MeshReaderBase

maspack.geometry.io.WavefrontReader

All Implemented Interfaces:

MeshReader

Direct Known Subclasses:

GeomagicObjReader

public class WavefrontReader
extends MeshReaderBase

Interprets a subset of the Alias-Wavefront OBJ file format. Groups are implemented, but only one group may be specified at a time and grouping applies only to faces, lines, curves, and surfaces.
