isOnNode

public boolean isOnNode()

Determines whether this location is on a node.

Returns:

true, if on a node; false, otherwise.

isOnEdge

public boolean isOnEdge()

Determines whether this location is on an edge.

Returns:

true, if on an edge; false, otherwise.

isInside

public boolean isInside()

Determines whether this location is inside a tri.

Returns the node.

Returns:

the node; null, if not on a node.

edge

public TriMesh.Edge edge()

Returns the edge.

Returns:

the edge; null, if not on an edge.

tri

public TriMesh.Tri tri()
