could you please extend rs python method rs.ViewProjection() with an additional return value for TwoPointPerspectiveProjection? It seems this is missing in comparison to RhinoScript (vb) syntax. I guess it just need this this line to get:
if viewport.IsTwoPointPerspectiveProjection: rc = 3
and this line to set:
elif mode==3: viewport.ChangeToTwoPointPerspectiveProjection(distance, up, 50)
thanks,
c.
