Field Summary

Fields inherited from class edu.jhu.htm.geometry.ConHelper

conv, domain

Constructor Summary

Chull()
use this f you are going to add all points then call makeConvex()

Chull(double[] ras, double[] decs)
pass points in two arrays

Method Summary

void	add(double ra, double dec) add point to polygon - checks for existing points
void	add(Vector3d v)
Convex	getConvex() may not have a convex if makeCOnvex was not called
void	makeConvex() call this if you are done adding points to actually construct the convex for the points get Convex does this anyway though if conv is null..
