I don't understand what I'm doing wrong. Here's what my Infovisitor outputs:
osg:Node:Group
osg:Node:Group db
osg:Node:OcclusionQueryNode OQNode_0
osg:Node:Group TableChairs
osg:MatrixTransform:MatrixTransform
osg:Node:ProxyNode
osg:Node:Group db
osg:Node:Group Chair1_84
osg:Geode:Geode p3004
osg:Drawable:Geometry
osg:Drawable:Geometry
osg:Geode:Geode p1077
osg:Drawable:Geometry
osg:MatrixTrnasform:Matrixtransform
osg:Node:ProxyNode
osg:Node:Group db
osg:Node:Group Chair1_84
osg:Geode:Geode p3004
osg:Drawable:Geometry
osg:Drawable:Geometry
osg:Geode:Geode p1077
osg:Drawable:Geometry
...another 2 times, for a total of 4 Chair1_84s.
using the polytope intersector, I collect the hits into a group but use
grp->containsNode(hit) to avoid the ~5000+ hits because all I'm interested is
how many (logical) objects there are visible in the scene. I thought I might be
able to store the matrixtransform in the group node, getting 4 different
matrixtransforms but that's not the case. I see 4 chairs on my screen, but can
only find one distinct node.
Why? How can all 4 chairs I see on the screen all reference the same
matrixtransform?
