[osg-users] Visualizing a light cone in scene

[Suraj Paul]

Hi David,

Thanks for the tips on my problem. 
Yes, i am trying to use (at present) light cone to show in my scene what its highlighting. But it fails to show the cone light beam emanating from the aircraft. 

As u suggested, i tried with transparent cone. But The problem is i am not able to position the cone vertically down the aircraft with the apex of cone touching the aircraft body. This is due to fact that OSG::cone takes height information as (0,0,height). I am not able to pass the x, y components of apex of cone. 

I Guess, i need to tweak the cone rendering. But dont know how to go about it.



... 

Thank you!

Cheers,
Suraj
