Sp2 / Sp3

Rebuilding the app meant focussing on the core functionality of the tool. It meant saying goodbye to some of the lesser used and more esoteric features. If you feel strongly about the loss of any of these, let us know.


For instance, the Superpolator2 colorfield: vital in building the math, but it was also rather slow and complex. Superpolator3 offers a color background to help you navigate the different axis combinations.

The Neutral Font

In Superpolator2 axes had to be defined around the origin. The master inserted at this special location (zero in all dimensions) had special powers. It dictated the character set and it was the compatibility template for all glyphs.

Superpolator3 lets go of the origin. Axes can stretch over any numerical range. So for instance 6 to 72 (if you’re setting up a classically proportioned optical series), or 0 to 255 if you think 8 bit number sound warmer, or 0 to 1000 if you’re used to old fashioned Multiple Master coordinate spaces. Or you could line up your coordinates with actual stem measurements.
This offers some exciting new possibilities for constructing designspaces, and those will be covered in a separate article.


All masters and instances are now in a single list. Double click on an entry to edit names, location and other settings in a popover. Control click on each item for more features.

The animation buttons are gone for now. Again, a lot of controls and overhead. Superpolator3 has extended the functionality of the designspace, making it more fun to play around in and explore the shapes.

The stemfinder feature has been replaced by an excellent new measuring tool.

Superpolator2 offered some support for interpolating PostScript hints for UFOs exported from FontLab using RoboFab. This data is not part of the UFO2 specification and is currently not supported.
