[osg-news] Collision detection with drawable

[Peter S. <ps...@ac...>]

Hello,

I'm trying to do collision detection with a drawable. The drawable's
vertices are stored in an aggregated geometry (the vertices are animated =
and
therefore changed each frame) and the bounding box is calculated correctl=
y,
but I can't get any collision detection. In the drawable's accept method =
I
have tried to both just pass the primitive functor to the geometry's acce=
pt
method, that is

_geometry->accept(prim);

and to pass the bounding box with consecutive calls to prim.vertex() with
the bounding box vertices. This worked a few months ago, but right now it
doesn't. Is there anything else I must do to get ray intersect to work?
