[Paraview-developers] Conference (was Is anyone using the Extra Headlight in ParaView?)

[Scott, W Alan]

Tim,
What conference were you attending?  How many students attended?  Any good positive or negative feedback?  Did you use your own training notes, or one of the ones in the paraview.org/ training page?   Ideas are always welcome!

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.

No objection here.  Only thought I have is that the lights may be setup by default slightly differently for 2d and 3d.  We may want a “headlight” for 2d.

By default, Paraview illuminates the scene with a vtkLightKit<http://www.vtk.org/doc/release/5.0/html/a01682.html>. You can however add an extra headlight. I am about to add a more general capability which lets you add any number and any kind of light, including the headlight. When I do that, the semi-hardcoded extra headlight becomes redundant. I would like to remove it to streamline both the code and the UI.
Are there any objections to me doing that?
