Constructor Detail

ObjTriangleMeshReader

public ObjTriangleMeshReader(Reader reader,
                             Precision.DoubleEquivalence precision)

Construct a new instance that reads OBJ content from the given reader.

Parameters:

reader - reader to read from

precision - precision context used to compare floating point numbers

Method Detail

readTriangleMesh

public TriangleMesh readTriangleMesh()

Return a triangle mesh constructed from all of the OBJ content from the underlying reader. Non-triangle faces are converted to triangles using a simple triangle fan. All vertices present in the OBJ content are also present in the returned mesh, regardless of whether or not they are used in a face.

Returns:

triangle mesh containing all data from the OBJ content

Throws:

IllegalStateException - if data format error occurs

UncheckedIOException - if an I/O error occurs

handleVertex

protected void handleVertex(Vector3D vertex)

Method called when a vertex is found in the OBJ content.

Specified by:

handleVertex in class AbstractObjPolygonReader

Parameters:

vertex - vertex value

handleNormal

protected void handleNormal(Vector3D normal)

Method called when a normal is found in the OBJ content.

Specified by:

handleNormal in class AbstractObjPolygonReader

Parameters:

normal - normal value
