Did you ever find a good solution for this? I need to be able to pick Particle Systems / Effects as well, and there seems to be 3 different routes for accomplishing this:
1) Implementing the Drawable::accept(PrimtiveFunctor) method in osgParticle::ParticleSystem as suggested above. 2) Add intersection support in ParticleSystem based on its defaultBoundingBox. 3) Adding custom geometry that is always culled, but can be used for intersection testing (Ref: the recent "picking and custom active area" thread)
Any thoughts on what's the best approach?
