Intersection.intersectShapes(shape1, shape2)

[iklotzko]

I was using this utility and found it returns all the intersections shape1 or shape2 have, in addition to eachother.

for (var ix = 0; ix < weird_shapes.length; ix++) {
        var p = weird_shapes[ix];

        var path = p.getMyShape();
        var shape = new Path(path);
        var rectObj = new Rectangle(actualRect);
        var intersection = Intersection.intersectShapes(shape, rectObj);

}

the same intersection is seen for many shapes... In order to obviate this I had to determine using the points in the intersection and see whether or not they were in my shape much easier than determining if my shape was in my shape.

Do I have to re-initialize the Intersection object somehow on each test for intersectShapes?

iklotzko,

Just to help me reproduce the issue, is there a specific combination of shape types that you are using?

Regarding the Intersection object, the "static method" intersectShapes creates a new Intersection object each time you call it. The rest of the state is maintained within the "static methods" off of intersectShapes, so no re-init is necessary.

hmmm, not sure what you would call them but cutting up a circle into pizza pie-like slices, and using a rectangle to select various items.
