Cumulus
A cloud and paint engine for weather. A cloud is a tree of lobes, lit by marching toward the light; brushes lay grain, wet paint and smudge over it. The letters above are a cloud grown along the skeleton of the word.
01The brush
Paint the weather
The surface is float, in linear light, so glazes never band. Export re-paints every stroke at 2880 by 3840 px instead of enlarging the screen.
One cloud file, four readings. The same description feeds the engine's raymarcher; the tests hold the outline to an IoU of 0.9 against a volumetric reference.
02The grid
Ledger
Each entry is one prism. Its length is the value, its direction the change: up and right when the series rose, down and right when it fell. Ink comes from the value's rank, side faces print as halftone, and the largest values carry a key ink set a little off register.
The series here is the 49 shot lengths of a brand film measured in this study, on a log scale, so the grid writes out that film's edit rhythm, entry by entry.
