Hello all,

 

I followed the bullet demo for picking object and was able to successfully add it to my pet project.

 

What I am trying to do and failing is to have a rubber band selection in my opengl window.

My though are on this line. A rubber band is pretty much a 2d box so I can easily get the 4 cornes and similalry to the demo for single click picking I can get the near and the far points for each of my corners. Thus I will have 8 points or a frustrum if you wanna call it as such.

 

How can I use bullet to get all my objects that reside in that frustrum ?  

I have been reading that I can do it either via the btPairCachingGhostObject or btGhostObject.

 

Anyone can provide a simple example ?

 

Thanks in advance
