Enable Anti-Aliasing #93

Open carlsonp opened 12 years ago

This may be something easy that may improve the visualization. Based on this:

It looks like enabling anti-aliasing in OSG is fairly straightforward. Perhaps something like:

traits = osg.GraphicsContext.Traits()
traits.samples = 4

I tried this but it was after the graphics was setup and it crashed. I think this will have to be done right when the graphics are initially setup and I'm not quite sure where that's at.

OSG isn't setting up the graphics contexts (plural - two per stereo display at least, I think), VR Juggler is. I'm pretty sure I asked a question on the VR Juggler mailing list and/or on their bug tracker - in any case, that would be the way to go. (And yes, I agree that antialiasing should be used)

In the frame buffer section of the JCONF, there appears to be something that may enable AA.

<num_sample_buffers>0</num_sample_buffers>
<num_samples>0</num_samples>

Changing the number of samples to 4 and 8 didn't seem to do much but actually testing this is difficult because it's such a minute adjustment. I don't think I can distinguish when it's on or off. :) I will read up to see if these are documented in VRJuggler.
