Hi, Oliveira,
there maybe many reasons that why no intersection. I cannot give you advise without more information. u can check about examples within OSG source code, e.g. "osgintersection". -- Cheers, --- TianZJ At 2017-01-03 17:55:02, "Bruno Oliveira" <[email protected]> wrote: Hi TianZJ, Thanks for the quick answer. I checked the intersector, but intersector->getIntersections() returns no intersections at all. 2017-01-03 9:32 GMT+00:00 tianzjyh <[email protected]>: Hi, Oliveira, You can check the intersections of your intersector(e.g. LineSegmentIntersector::Intersection), and you will find they contain an "osg::NodePath", which means the whole path of the node(e.g. matrix transform nodes upon the drawable instance). -- Cheers, --- TianZJ At 2017-01-03 16:58:16, "Bruno Oliveira" <[email protected]> wrote: Hello, I'm implementing a draw instanced optimized scene. This is for drawing a set of polygons. Previously I was creating a drawable for each polygon, but now I am using draw instancing. With one drawable per polygon I can easily use osg intersectors for computing scene intersections. But how can I perform scene intersections with draw instanced objects and get, for instance, intersected instance IDs? _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
