Spectral Topography

The spectrum's history as a contour map: frequency across, time down, rhythm visible as banding.

Launch modes

Heat Ribbon mode

Heat Ribbon

Every past frame shaded by magnitude: the plot itself, no geometry.

Contour Lines mode

Contour Lines

Iso-level curves traced through the history, like a survey map.

Iso Bands mode

Iso Bands

The map as filled regions between levels rather than as lines.

Ridge Plot mode

Ridge Plot

Each past frame as an offset line, drawn back to front so nearer ridges occlude.

Wire Relief mode

Wire Relief

The history as a projected wireframe under a fixed viewpoint.

Flyover mode

Flyover

The same surface with the camera travelling along the time axis.
