Method Detail

getAdjacentTriangle

public DelaunayTriangulator.Triangle getAdjacentTriangle(int vi)

Returns the triangle adjacent to the edge between vertices vi and (vi+1)%3. Returns null if there is no adjacent triangle.

Parameters:

vi - local vertex index, in the range 0 to 2

Returns:

adjacent triangle, or null

getAdjacentTriangleIndex

public int getAdjacentTriangleIndex(int vi)

Returns the index (with respect to all triangles in the triangulation) of the triangle adjacent to the edge between vertices vi and (vi+1)%3. Returns -1 if there is no adjacent triangle.

Parameters:

vi - local vertex index, in the range 0 to 2

Returns:

adjacent triangle index, or -1

getPoint

public Vector2d getPoint(int vi)

Returns the point (from the input point set) for the vi-th vertex in this triangle. Vertices are arranged counter-clockwise around the triangle.

Parameters:

vi - local vertex index, in the range 0 to 2

Returns:

input point associated with the vertex

getPointIndex

public int getPointIndex(int vi)

Returns the index (with respect to the original point set) corresponding to the vi-th vertex in this triangle. Vertices are arranged counter-clockwise around the triangle.

Parameters:

vi - local vertex index, in the range 0 to 2.

Returns:

index of the vertex input point, or -1

getIndex

public int getIndex()

Returns the index of this triangle with respect to all triangles in the triangulation.

Returns:

triangle index
