[Paraview] [EXTERNAL] Is anyone using the Extra Headlight in ParaView?

[Timothy Dwight Dunn]

Actually I was just talking about this in a Paraview tutorial I gave this
morning at a conference. I would prefer to kill the hard coded light
allowing the ability to add in general lights that the user can design and
setup. In addition to save a conf out for the setup to be used as a
default. I normally set things up in Paraview export what I need pop them
in a CG app so that I can light them with so much more control but this is
often difficult at best to impossible as the norm due to complexity of the
scene. If we could get more and better light control, especially with
Osprey then I'd be a very happy camper.

Just to make really difficult make sure the lights interact with
objects/layers as desired by the user, including volumeterics. This is a
common thing to do in CG apps. Light objects A,B,C with light rig1, object
D,E with light rig2 and object F with light rig3 .... The easiest way to do
this is to have a panel for each light, or for paraview the gui controls
with a check box list for each available layer which can
activate/deactivate each light per layer. OK this makes sense in my head
but I don't think I'm explaining it well do to conference exhaustion. If
desired I can do a mock up gui layout image of what I'm trying to describe.
