Method Details

fit

public void fit(List<Point3f> points,
 Mark mark,
 Dimensions dimensions)
         throws PointsFitterException,
InsufficientPointsException

Description copied from class: PointsFitter

Fits a mark to a set of points within given dimensions.

Specified by:

fit in class PointsFitter

Parameters:

points - the list of points to fit the mark to

mark - the mark to be fitted (will be modified)

dimensions - the dimensions within which the fitting occurs

Throws:

PointsFitterException - if an error occurs during the fitting process

InsufficientPointsException - if there are not enough points to perform the fitting

isCompatibleWith

public boolean isCompatibleWith(Mark testMark)

Description copied from interface: CompatibleWithMark

Tests if the implementing object is compatible with a mark of a particular type.

Parameters:

testMark - the mark to test for compatibility

Returns:

true if the implementing object is compatible with the given mark, false otherwise

getMinRadius

public double getMinRadius()

setMinRadius

public void setMinRadius(double minRadius)
