Hello, Pretty much no - you need to rewrite your application using Delta's tools, otherwise Delta will not know about your code. Delta is not a library like OSG, it is a whole game engine. However, as Tony said, you do not need to use Delta for collision detection. osgBullet is one possibility, on the wiki there are examples of other engines as well (ODE, Havoc, PhysX, etc): http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials (look at the bottom, under External examples). In general, you need to define the physics body, usually by setting up the mass or some matrices and then the collision body - bounding volume of your mesh (inaccurate but fast) or the mesh itself (accurate but slow). The update of the engine data is typically done by a callback attached to your OSG node somewhere.
