mmm, I don't know what you exactly do, but as I've did the update, I've runned
a few tests.
results are identical per class:
intersect ray: Vector3D(0, 10, 20)
intersect rayThreeSix: Vector3D(0, 10, 20)
rayThreeSix == 3.6 class with updated imports
the rayDebugger class, is a private class of mine, dedicated to ray traces.
the two functions used here, are simply, 1 tracing a segment and the other
adding a cube at intersection if any.
------------
testcode
------------
private function testRay() : void
{
_rd = new RayDebugger(_view.scene);
var rayThreeSix:RayThreeSix = new RayThreeSix();
var ray:Ray = new Ray();
var v0:Vector3D = new Vector3D(-200, 100, 20);
var v1:Vector3D = new Vector3D(200, 100, 20);
var v2:Vector3D = new Vector3D(0, -200, 20);
//display the target face
_rd.traceRay(v0, v1, 0xFFFFFF);
_rd.traceRay(v1, v2, 0xFFFFFF);
_rd.traceRay(v2, v0, 0xFFFFFF);
//some destination point
var dest: Vector3D = new Vector3D(0, 10, 10);
// we trace trajectory
_rd.traceRay(_view.camera.position, dest, 0x00FF00);
var intersect:Vector3D;
intersect = ray.getIntersect(_view.camera.position,
dest, v0, v1, v2 );
trace("intersect ray: "+intersect);
//if not null --> lets add a cube at the intersect
vector
if(intersect)_rd.addPointer(intersect, 20);
intersect =
rayThreeSix.getIntersect(_view.camera.position, dest, v0, v1, v2 );
trace("intersect rayThreeSix: "+intersect);
//if not null --> lets add a cube at the intersect
vector
if(intersect)_rd.addPointer(intersect, 20);
var trident:Trident = new Trident(250, true);
_view.scene.addChild(trident);
}
here's what the above code does and looks like in Broomstickland.

In short both class getIntersect methods return correct and same results in
both 3.6 and 4.0.
Played with few different values and never were the results different from a
class to the other or incorrect on display/debug.
Note that it would be very strange unless a typo would have been made, because
the new one simply replace the Vector3D native methods to avoid these stupid
new construct returns.
