Method Detail

identifyVertices

public static int identifyVertices(PgElementSet geom,
                                   double eps)

Identify vertices which are identical, or within an epsilon box of each other.

Parameters:

geom - Geometry whose vertices shall be identified

eps - tolerance of coordinate components, not distance

Returns:

number of removed vertices

markVertices

public static void markVertices(PgElementSet geom,
                                double eps)

Mark vertices which are identical, or within an epsilon box of each other.

Parameters:

geom - Geometry whose vertices shall be marked

eps - tolerance of coordinate components, not distance

removeMarks

public static void removeMarks(PgElementSet geom)

Remove tag IS_SELECTED from all vertices in geometry.

getDialog

public static void getDialog(PgElementSet geom)

Get dialog to configurate identifying of close or equal vertices.

removeDegenerateElements

public static void removeDegenerateElements(PgElementSet geom)

Adapt triangulation to the following conventions: - the vertices of an element must be pairwise different. - every element has at least three vertices.

isDegenerated

public static boolean isDegenerated(PgElementSet geom)

Checks whether edges of elements have length smaller than PuMath.EPS.

orientate

public static void orientate(PgElementSet elSet)

Try to orientate all elements of the PgElementSet according to the orientation of all their neighbour elements. This will obviously lead to a success only for orientable surfaces.
