Add Super Sampling Anti Aliasing to ParaView
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Please add super sampling anti aliasing (SSAA) to ParaView for drawing the 2d/3d rendering windows when non-interactive rendering. Make this SSAA work when saving screenshots or saving animation. Allow the user to turn it on/off in the Edit/Settings, but also select-able from the save screenshots/ save animation dialogs. Maybe allow the user to designate how much super sampling is being done?
From an e-mail thread with Ken Martin:
I was thinking SSAA , aka render into an FBO at sqrt(3)*width by sqrt(3)*height for example and then down sample back to the window size, for picking just bypass it. I have looked into FXAA, CMAA, but both those approaches are typically faster, but have more complex implementations and are subject to artifacts (CMAA is better on artifacts but the implementation is more complex). A first step could be to use it for the non-interactive renders in PV.
