Convert 3d coordinates to 2d.

Scripting Issues

I have found that the above doesn’t work well when the node is not parented to render itself, but to some other node. The following modification works well in any case:

def nodeCoordIn2d(nodePath):
    coord3d = nodePath.getPos(base.cam)
    coord2d = Point2()
    base.camLens.project(coord3d, coord2d)
    coordInRender2d = Point3(coord2d[0], 0, coord2d[1])
    coordInAspect2d = aspect2d.getRelativePoint(render2d,
                        coordInRender2d)
    return coordInAspect2d
