class bruhanimate.bruheffect.perlin_effect.PerlinEffect(buffer: Buffer, background: str, settings: PerlinSettings = None)

Bases: BaseEffect

Smooth animated noise field.

Multiple octaves of sine-wave interference are combined to produce fractal-like smooth noise that scrolls and pulses over time. A configurable threshold gates which parts of the field are drawn, controlling density. Color maps noise intensity through a heat palette when enabled.

__init__(buffer: Buffer, background: str, settings: PerlinSettings = None)

Base class for all effects.

Parameters:

• buffer (Buffer) – Effect buffer to push updates to.

• background (str) – character or string to use for the background.

render_frame(frame_number: int)

To be defined by each effect.
