Hi Robert,

We did do working on support HUD/Ortho2D picking between pre 1.x days
and now.  If you can try upgrading.

I'm using sceneview->projectObjectIntoWindow to draw an ortho2D line
from the edge of the viewport to an object location in the scene.

It's working fine until I fly low and slow directly over the object and
it gets under and behind me (i.e. out of view).  Initially the window xy
coords being returned hang in there; y goes negative but all still
visually looks OK (for ex x=1569, y=-1843), the line just gets clipped
at the bottom edge of the viewport.  But then suddenly it starts
returning a large negative x and positive y for window coords (for ex:
x=-2188 y=3986, return code still =true(success)), which, as I keep
flying slowly forward quickly converges into small, positive x,y (for
ex: x=90, y=580) and the line starts pointing somewhere out on the
horizon, but the object location is behind and under me.

Is this to be expected, or am I doing something wrong?  Can I prevent
this from happening?  [Note: I'm stuck for now on pre 1.x, so could this
also be a bug that has been fixed?].


Bob.
