[Paraview-developers] Anti-aliasing of triangles

[Ken Martin]

I do want to add in a SSAA pass to VTK.  From a code perspective it should
be fairly easy and then you should be able to have AA triangles safely etc.

FYI, it also messes up lots of other rendering modes (like depth peeling
and picking). We had enough trouble with it that we shut it off all the
time.

Because it messes of parallel compositing.



A workaround is to render large images (4x wider and 4x taller) and then
resample them down in some image editor.

I have a customer asking why we don’t antialias our triangles?  You can see
this with the (very slightly) raged edge on the sources/sphere.



Thanks,
