Method Detail

makeNGon

static OTSShape makeNGon(int numVertices,
                         double r,
                         double cX,
                         double cY)
                  throws OTSGeometryException

Create and return an OTSShape.

Parameters:

numVertices - int; the number of vertices in the constructed OTSShape

r - double radius of the constructed OTSShape

cX - double; x-coordinate of the center of the constructed OTSShape

cY - double; y-coordinate of the center of the constructed OTSShape

Returns:

OTSShape

Throws:

OTSGeometryException - when the number of vertices is less than two, or the radius is 0;

baseTest

public static TestIntersectionPerformance.Results baseTest(int numShapes,
                                                           int numVertices,
                                                           double desiredHitFraction,
                                                           int numRuns,
                                                           boolean verbose,
                                                           int variant)
                                                    throws OTSGeometryException

Perform a test.

Parameters:

numShapes - int; number of shapes to construct

numVertices - int; number of vertices in each constructed shape

desiredHitFraction - double; intended fraction of shapes that overlap a randomly selected shape

numRuns - int; number of runs to execute

verbose - boolean; if true; print details of each run

variant - int; variant of the collision tester to use

Returns:

Results; collected statistics of this test

Throws:

OTSGeometryException - when the number of vertices iss less than two
