All,
I have a couple of questions regarding LineSegmentIntersector.
I noticed that for a given line segment, it currently computes and
returns ALL intersections with a given geometry in the scene.
My questions are:
1) Does it support a feature of detecting a hit and then
Hi Shayne,
The base osgUtil::Intersector class supports setting the limits on
intersection results, using the setIntersectionLimit() method. The current
options are NO_LIMIT, LIMIT_ONE_PER_DRAWABLE, LIMIT_ONE, LIMIT_NEAREST.

Is this functionality of setting limits on intersection results only

Yes, the default is NO_LIMIT. I'm using it in version 2.9.12, but I think I

Hi Farshid,
Your method is interesting. Before I've tried to use isCulled from CullVisitor

So I've tried to manually do the test using Polytope for the frustum check and

with some easy flash demos :P
Oh, you mean GameSWF. Yes it is in my TODO list. But in fact GameSWF
doesn't handle AS3 so it may not be enough for Flash UI needs. I was
interested in Vektrix before, which provides a better framework for
Flash and AS3 (using Tamarin), but it seems inactivated now.
