Tennis ball mathematics, rendered live.
Four parametric equations that describe the geometry and motion of a tennis ball, rendered as real-time ASCII art and a 3D point cloud. A technical workshop note from the Surge lab.
Parametric Shapes
Select a shape to explore.
Each shape is defined by parametric equations and rendered in real-time as ASCII characters mapped by depth.
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.
