I'm using your module and it is a very great tool! But unfortunately it is not works if I want to slice by counter-clockwise polygons. I rewrote the testLineAndRing method within the module, and it works now, but only with counter-clockwise. Can someone recomment an ultimate solution?
I know I can check it with shoelace formula, and use one of the two methods in the particular cases, but I'm looking for a more simple solution.
My script is:
`
var tempSegments = [];
var cutPoints = [];
var actualSegment;
for (var k = 0; k < segments.length; k++) {
var curr = [];
for (var l = 0; l < segments[k].length - 1; l++) {
curr.push(segments[k][l]);
actualSegment = segments[k][l];
//Collecting the intersection points
for (var m = 0; m < ring.length - 1; m++) {
if (equal(segments[k][l], ring[m])) {
tempSegments.push(curr.slice());
curr = [segments[k][l]];
continue;
}
var is = linesIntersect(
segments[k][l],
segments[k][l + 1],
ring[m],
ring[m + 1]
);
if (is) {
cutPoints.push(is);
}
}
}
while (cutPoints.length > 0) {
//Which is the closest point?
var minDist = Number.MAX_VALUE;
var minDistSpot = -1;
for (var c=0; c < cutPoints.length; c++) {
if ( getDistanceByEndpoints(actualSegment[0],actualSegment[1],cutPoints[c][0],cutPoints[c][1]) < minDist ) {
minDist = getDistanceByEndpoints(actualSegment[0],actualSegment[1],cutPoints[c][0],cutPoints[c][1]);
minDistSpot = c;
}
}
curr.push(cutPoints[minDistSpot]);
tempSegments.push(curr.slice());
curr = [cutPoints[minDistSpot]];
cutPoints.splice(minDistSpot,1);
}
curr.push(segments[k][segments[k].length - 1]);
tempSegments.push(curr.slice());
}
