Field Detail

debugOffsetLine

static boolean debugOffsetLine

Debugging flag.

circlePrecision

static double circlePrecision

Precision of approximation of arcs in the offsetLine method.

offsetMinimumFilterValue

static double offsetMinimumFilterValue

Noise in the reference line less than this value is always filtered.

offsetMaximumFilterValue

static double offsetMaximumFilterValue

Noise in the reference line greater than this value is never filtered.

offsetFilterRatio

static double offsetFilterRatio

Noise in the reference line less than offset / offsetFilterRatio is filtered except when the resulting value exceeds offsetMaximumFilterValue.

Method Detail

offsetLine

public static OTSLine3D offsetLine(OTSLine3D referenceLine,
                                   double offset)
                            throws OTSGeometryException

Construct an offset line.

Parameters:

referenceLine - OTSLine3D; the reference line

offset - double; the offset; positive values indicate left of the reference line, negative values indicate right of the reference line

Returns:

OTSLine3D; a line at the specified offset from the reference line

Throws:

OTSGeometryException - when this method runs into major trouble and cannot produce a decent result
