[Paraview] Revisiting aliasing effect

[Den Fairol]

Hi, 

 

I'm a little confused regarding the inconsistent behavior of ParaView
(v4.x), specifically the quality of its volume rendering representation. The
Smart/GPU renderer for Windows version is slightly inferior to its RayCast
renderer counterpart whereas for the Unix/Linux version, it is kind of like
something you'd expect from a 'B' horror movie (see attachment for
Smart/GPU-based rendered images). It is mentioned here:
http://www.paraview.org/pipermail/paraview/2011-June/022062.html &
http://www.paraview.org/pipermail/paraview/2010-June/017961.html that
anti-aliasing (AA) is disabled by default. Then how could the Windows
(Windows 7, NVIDIA Quadro 600 + driver v320.xx) version persist to appear so
smooth despite setting NVIDIA's Control Panel AA handling to 'Off'?
Conversely, changing the same option in Linux (Ubuntu 12.04, NVIDIA Quadro
K5000 + driver v304.xx/v319.xx/v331.xx) to 'Override-application' adds
nothing to the quality. As of now, RayCasting is may not be a viable
solution since it induces substantial latency overhead.

 

Regards,

Den
