Workshop Note
Tennis Math
A visual study from the technical workshop behind Surge. This page explores tennis-ball geometry, motion, and rendering patterns in public. It is not a scouting surface; if you want the clearest public proof of the product, start with Tour Radar.
Why This Exists
Surge occasionally publishes narrower technical notes that sit adjacent to the product. Tennis Math is one of those notes: a public notebook about geometry, motion, and visual explanation around the ball itself.

Start With The Flagship
Tour Radar is the public scouting surface. This page is a workshop artifact from one layer behind it.

What You Are Seeing
The spherical base of a tennis ball, rendered by looping through latitude and longitude angles and converting to 3D Cartesian coordinates. Each point maps to an ASCII character by depth.
