Mesh impostors on 3D object like path?

 

I use babylon.js and oimo.js

 

I read this instructions here

 

On this page is mention that

there are 4 impostors:

1. Box

2. Sphere

3. Capsule

4. Mesh

Which of this 4 impostors are supported in oimo.js ???

Which js implement collision oimo.js or babylon.js ???

 

With Blender I did:

I create some simple path and one ball.

I set physic collisions and rigid.

Path objec has Mesh - collision (Mesh Impostor). 

In blender animations works fine.

I attach file "path_example.zip" 

 

I try "http://www.babylonjs.com/sandbox/" and load "path_example.babylon"

Babylon sendbox doesn't work as it works in blender.

 

Does Oimo.js doesn't support Mesh Impostor ?
Which file implement Impostor or collision? Do babylon.js implemennt this or oimo.js?

 

Is there any other solution to solve this.

 

I would like to rotate path object (rotate throught all axises x, y, z) at runtime in babylon game engine.
It is possible to solve this withouth Mesh-Impostor (Mesh collision shape on Path).
I don't want to have static path. I would like to rotate it and I would like to use physic on ball and path objects.

 

Is there any other possible sollution.

Can I create colider-boxes around path and join this colider-boxes to one collider-object, because I would like

to rotate all box colliders as one model at runtime (I don't want to have seperated collider-boxes and static path!)

 

Pleas help me. 
Can give me any advice or hint?

 

Thanx
