Demos

This section contains content related to the demos package.

Overview

Each demo is a standalone runnable example of an effect or composed scene. There are two ways to run a demo:

From Python:

from bruhanimate import plasma_demo
plasma_demo.run()

From the command line:

python -m bruhanimate.demos.plasma_demo

Every demo defaults to on_resize="resize" and continues playing when the terminal changes size. The typed on_resize argument also accepts "raise" if you want resizing to stop playback. See Terminal resize for the policy.

All built-in simulations adapt their areas using documented state policies. The dashboard reflows its layout. The TV demo recenters its original computer artwork; fixed layer regions and moving window bounds are not rebuilt. Cycling showcases preserve their phase clocks and notify inactive effects too, so later phases use the new viewport.

The Nature Gallery gallery combines six natural/procedural effects. See Water, smoke, cloth, and procedural worlds for settings and presets.
