Package: dolphin.lightlab | Status: source-declared

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

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

```yh
external thing dolphinGpuEffects
```

- int preMask: Stores pre mask as int.
- int jitter: Stores jitter as int.
- int exposure: Stores exposure as int.
- int vignette: Stores vignette as int.
- int glowStrength: Stores glow strength as int.
- int environmentMask: Stores environment mask as int.
- dolphinGpuEffects(): Dolphin gpu effects.
- Valid() returns bool: Valid.
- EnvironmentKey() returns text: Environment key.
- PreKey() returns text: Pre key.
- Key() returns text: Key.

## Use dolphinGpuEffects

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.
dolphinGpuEffects sample = dolphinGpuEffects()
Console.Log(Text.From(sample.preMask))

```
