i tried to draw a triangle... and what i find...  i think that there is =
a
simple bug in collision_trimesh.cpp

    void dGeomTriMeshGetTriangle(dGeomID g, int Index, dVector3* =
v0,dVector3* v1, dVector3* v2){
    ....
        FetchTriangle(Geom, Index, Rotation, Position, v);     // =
Original
        FetchTriangle(Geom, Index, Position, Rotation, v);     // =
Corrected
    ...
    }

and

    void dGeomTriMeshGetPoint(dGeomID g, int Index, dReal u, dReal v,  =
dVector3 Out){
        ....
        FetchTriangle(Geom, Index, Rotation, Position, v);     // =
Original
        FetchTriangle(Geom, Index, Position, Rotation, v);     // =
Corrected
        ...

    }

because function defining in collision_trimesh_internal.h is

inline void FetchTriangle(dxTriMesh* TriMesh, int Index, const dVector3
Position, const dMatrix3 Rotation, dVector3 Out[3])
{
....
}
