Still, in practice, roughly 2x is usually perfect in terms of image quality, disk space, and processing speed. If you do need 3x or more antialiasing, you can adjust line thickness in paraview to be more than 1 pixel thick, so that you can control your final line thickness. (In practice, file size scales less than linearly with resolution because the scaling often does not introduce extra detail). So you probably don't want your antialias scale to be more than 3x because your lines will disappear, because you get diminishing returns on improved image quality, and because frames saved at 3x the desired resolution could have up to 9x the file size and 9x the processing time. So drawing oversized at 2x and then averaging down by 1/2 to get 1x, you see final lines that appear to be 1/2 a piel thick (they appear partially transparent to cause the illusion of subpixel thickness). Keep in mind that when ParaView saves an oversized frame, it still draws single pixel lines only only one pixel thick.

Where convert is a command line utility from the free ImageMagick package. But to anti-alias at 2x, I save it as 3840x2106 pixels, and then run:Ĭonvert -geometry 1920x1080 bigframe.png antialiasedframe.png For an image with jaggies, I'd just save that. For example, I want a nice HD frame at 1920x1080. To do this, we render our images at somewhere between double and triple normal resolution, and then use a separate tool to average them down to the desired size. To get nice lines, we need anti-aliasing. Often lines or edges appear to have "jaggies" or stair stepping when they are nearly vertical or horizontal.

If you've got an HD movie, but have to present it on a square monitor, will it look good with the sides chopped off? Or would it look better shrunk down with empty space above/below the movie on the display? I prefer to make it look good in HD (1920x1080), with an eye to possibly chopping off the left/right sides for more square displays (so preview what that would look like, and if that's good too, you're golden). It's good to think about what your movie will look like in other common aspect ratios. Even if you save movie frames at another resolution, if they have the same aspect ratio, you will get an accurate sense of the final appearance by looking at the locked 3d view in ParaView. Now, what you see (except for overall size) is pretty much what you get. To avoid this problem, you can lock the 3d window's resolution via "Tools -> Lock View Size Custom.". If these don't match, then the image you see in ParaView won't match the image you see in your movie frames.

In ParaView, the aspect ratio of what you see in the GUI may not match the aspect ratio of the display where your final movie will be displayed. If you have to choose something less usual, there is a nice diagram showing other options here.

To prepare for 3D PDF Brochure production, the resolution should be resampled down to a modest 8000 by 4000 pixel size. For the web, this huge image is then processed into a spherical view for publishing in HTML5 or, as a fall-back, Flash. * Probably best to use this for your master frames, then crop/resize as needed for movies of other resolutions/aspect ratios. The resulting image can be huge 2.5 Gigabytes in the Sheldonian Theatre example.
