Yes, the values in res are garbage when its pointer is passed to the
find_closest_intersection function. But then, the values of the
members in res(t, u, v , tindex) are modified in that function after
intersect_triangle routine is called. The raytrace function is then
having the modified res.

......
if(intersect_triangle(r->origin, r->direction, obj->vert[obj-
>tri[i].v0], obj->vert[obj->tri[i].v1], obj->vert[obj->tri[i].v2],
&res->t, &res->u, &res->v) == TRUE)
.......

^^ The values in res are getting modified here. res->hit is modified
inside the if clause. The res->tindex is modified after the for loop
and it is assigned the value of the variable index.
