Hi Mihai,
Sorry for late answer, but i still not have internet connection correct
running at my new home place :-(
I like to integrate it into the osg core. there are serveral advantage when
it's propery integrated:
(A) Intersection / Ray Test can become really fast
(B) Collision Checks
(C) Haptic Rendering can become also much faster, i still implemented once
for the Phantom device a kd-Tree based structure.
Kd-Tree is a known fast structure for finding neighbours in a 3D scene
(Hint: Iterative Closest Point)
(D) ..
It' would be really greate if some osg member can help me. because there is
a lot of work to be done.
(i) kd-Tree has to be fast: w.r.t build and ray test (i did still lot of
progress, Real Time RayTracing: Ingo Wald , and others)
(ii) osg core integration, w.r.t to replace own BHV, means best integration
would be if we can add kd-Tree as default, but users
are open to easy replace it, with their own structure
(iii) testing and optimising,
(iv) update problem
...
(Append X for ii ) w.r.t RealTime RayTracing ... may we can also thing about
how we can append material and so on :-)
