Constructor Detail

SimpleFacetDefinition

public SimpleFacetDefinition(List<Vector3D> vertices)

Construct a new instance with the given vertices and no defined normal.

Parameters:

vertices - facet vertices

Throws:

SimpleFacetDefinition

public SimpleFacetDefinition(List<Vector3D> vertices,
                             Vector3D normal)

Construct a new instance with the given vertices and normal.

Parameters:

vertices - facet vertices

normal - facet normal; may be null

Throws:

IllegalArgumentException - if vertices contains fewer than 3 elements

Method Detail

getVertices

public List<Vector3D> getVertices()

Get the facet vertices.

Specified by:

getVertices in interface FacetDefinition

Returns:

facet vertices

getNormal

public Vector3D getNormal()

Get the normal defined for the facet or null if one has not been explicitly specified. No guarantees are made regarding the properties of the normal or its relationship to the vertices.

Specified by:

getNormal in interface FacetDefinition

Returns:

the defined normal for the facet or null if one has not been explicitly specified

toString

public String toString()

Overrides:

toString in class Object
