Interface DeltaCallback64

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface DeltaCallback64

Functional interface for calculating a variable delta during polygon offsetting.

Implementations of this interface define how to calculate the delta (the amount of offset) to apply at each point in a polygon during an offset operation. The offset can vary from point to point, allowing for variable offsetting.

Method Summary

double	calculate(Path64 path, PathD path_norms, int currPt, int prevPt)	Calculates the delta (offset) for a given point in the polygon path.

Method Details

calculate

double calculate(Path64 path,
 PathD path_norms,
 int currPt,
 int prevPt)

Calculates the delta (offset) for a given point in the polygon path.

This method is used during polygon offsetting operations to determine the amount by which each point of the polygon should be offset.

Parameters:

path - The Path64 object representing the original polygon path.

path_norms - The PathD object containing the normals of the path, which may be used to influence the delta calculation.

currPt - The index of the current point in the path for which the delta is being calculated.

prevPt - The index of the previous point in the path, which can be referenced to determine the delta based on adjacent segments.

Returns:

A double value representing the calculated delta for the current point. This value will be used to offset the point in the resulting polygon.
