When I compile and run v .39 it behaves differently then v .35
More specifically, i'm getting a different return value for
dBodyGetRotation(). I'm assuming the internals are doing something they
weren't before.
Here are the details:
I have a .Net wrapper for ode.(i'm pretty sure it's not a wrapper problem)
I call the a constructor to new-up a body object:
//constructor
Body::Body(ManagedODE::World * world)
{
_world = world;
_id = dBodyCreate (world->Id);
_geomList = new BodyGeomList(this);
}
Then, as a test I immediatly make a call to retrieve the rotation matrix for
the body:
Matrix3 Body::get_Rotation()
{
const dReal * rotation;
rotation = dBodyGetRotation(_id);
Matrix3 mat = Matrix3(rotation);
return mat;
}
The test app is identical, the only difference is one is using v.35 compiled
to use doubles and the other is using v.39 and is also complied to use
doubles.
Here is what the mat looks like in each case:
v.35:

v.39

Obviously the value i'm getting back from dBodyGetRotation is messed up or
at least different then it was in .35 Anyone have any ideas what might have
changed??
