Raycasting - Getting sequential collision objects

[sipickles]

Hello

I am using raycasting for mouse picking and its working well.

However, the result points to the first object that the ray collided with. Makes sense as I am using btCollisionWorld::ClosestRayResultCallback to retrieve the collision object.

So what if I want to find the next collision object, ie, the collision object BEHIND the first one hit, as if the ray had carried on.

Is this possible? Can I do it with a single ray? Or perhaps a second ray test from the first collision location, with the same direction vector?

Thanks

Simon
