I think I found a way.
I store the end point of my line (determined by the mouse position) into a Number3D, then iterate throught the do3d's on my scene, using the normalize and multiplyEq methods to find the position along the line at the same Z than the do3D. I can then hitTestPoint with that position ...
I'm just not sure about the normalize and multiplyEq methods... Is that the right way to do it ?
var pt : Number3D = new Number3D(e.renderHitData.x,e.renderHitData.y,e.renderHitData.z);
for(var ref:* in _view.scene.objects) {
var d:DisplayObject3D = _view.scene.objects[ref] as DisplayObject3D;
pt.normalize();
pt.multiplyEq(d.z);
if(d.hitTestPoint(pt.x,pt.y,pt.z)) {
touch = true;
}
}

Hi,
I have a Lines3D, with only one line, and a couple Plane objects on the scene. I want to check if the line intersects with one of the planes.
It seems like Lines3D.hitTestObject returns true all the time, even if it's not touching anything. I believe it is because the bounding sphere of the line is huge.
What would be the best way to check if a line intersects with a DO3D ?
Thanks,
