[ODE] dSpaceCollide2 for dGeomID and dSpaceID

[Flavien Brebion]

Taken from my own code:
    dSpaceID				m_odeCollSpace;			// ode's space ID
    dGeomID					m_odeRay;				// ray for hovering physics
    ...
    dSpaceCollide2(m_odeRay, (dxGeom *)m_odeCollSpace, this,
&nearRayCallback);

Never had a problem with it.

A space _is_ a geom. So you can use dGeomGetClass to get the geoms class
number and if it is dSimpleSpaceClass or dHashSpaceClass you can cast it to
a
dSpaceID.

But dSpaceCollide2 collides spaces not geoms. You could give it the space
that
contains the ray and the other space. You can get the rays space with
dGeomGetSpace.
