Hi,
        Could anyone please tell me. when could such a problem occur on
detecting an intersection.
        On querying the segset for intersections using
        isect = root->isect(&seg1,(pfHit ***)hits); isect is returned as
non zero. Here seg1 is a pfSegSet and hits is a pfHit * [][].
        On querying the point of intersection using PFQHIT_FLAGS,
transformation matrix is not valid.
        Enclosing Code :
        ------------------------------------------------------------
        isect = root->isect(&seg1,(pfHit ***)hits);
        unsigned int hit_flags;
        pfVec3 pnt,xpnt;
        pfMatrix xmat;
        if(isect)
        {
                (*hits[i])->query(PFQHIT_FLAGS, &hit_flags);
                if((hit_flags & PFHIT_POINT ))
                {
                        (*(hits[i]))->query(PFQHIT_POINT, pnt.vec);
                        (*(hits[i]))->query(PFQHIT_XFORM,(float*)xmat.mat);
                        xpnt.xformPt(pnt,xmat);
                }
        }
        ------------------------------------------------------------

        Hope someone can help.
        thanks in advance
regards,
Vidya
