A drawable point.
CG_Vertex(Number x, Number y)
Number x
|
x coordinate of the vertex.
|
Number y
|
y coordinate of the vertex.
|
CG_Halfedge h
|
The associated CG_Halfedge.
|
CG_HalfEdge handle(CG_Vertex v)
|
Creates and returns an associated CG_HalfEdge between this vertex and vertex v.
|
Boolean isIsolated()
|
Checks if there is a HalfEdge associated with this vertex. |
Boolean isLeaf()
|
Checks if this vertex is an endpoint. |
Boolean ccw(CG_Vertex a, CG_Vertex b)
|
Checks if this vertex is below the line spanned by vertices a and b.
|
Boolean visible(CG_HalfEdge, Boolean orient)
|
Checks if this vertex is within the plane spanned by the half edges h.prev and h with orientation orient.
|
CG_HalfEdge inFace(CG_HalfEdge, Boolean orient)
|
Checks if this vertex is in the face spanned by the half edge h with orientation orient. If so, it returns the half edge h. Otherwise, it returns the first half edge c such that visible(c, orient) = false.
