Package: dolphin.lightlab | Status: source-declared

Tags: class, cpu, dolphin, dolphin.lightlab, lightlab, method, source-example

Build bounded lighting experiments with geometry, visibility, transport, film, and GPU/CPU contracts.

```yh
external class dolphinLightFilm
```

- list of dolphinLightPixel pixels: Stores pixels as list of dolphinLightPixel.
- dolphinLightFilm(): Dolphin light film.
- Reset(int width,int height) returns bool: Reset.
- Accumulate(int index,dolphinLightSample value) returns bool: Accumulate.
- Resolve(int x,int y,bool denoise) returns Vector3: Resolve.

## Use dolphinLightFilm

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using dolphin.lightlab

// Build bounded lighting experiments with geometry, visibility, transport, film, and GPU/CPU contracts.
dolphinLightFilm sample = dolphinLightFilm()
Console.Log("Created dolphinLightFilm")

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
