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 dolphinGpuSignalVerifier
```

- buffer of int domain: Stores domain as buffer of int.
- dolphinGpuSignalVerifier(): Dolphin gpu signal verifier.
- History(buffer of float output,buffer of float geometry,buffer of float lighting,buffer of float history,buffer of float previous,buffer of float camera) returns bool: History.
- Filter(buffer of float output,buffer of float geometry,buffer of float input,buffer of float statistics,int width,int height,int inputStride,int step) returns bool: Filter.
- Compose(buffer of int pixels,buffer of float geometry,buffer of float lighting,buffer of float signals,buffer of float filtered,float exposure,int filterEnabled) returns bool: Compose.
- CoverageCompose(buffer of int pixels,buffer of float geometry,buffer of float lighting,buffer of float signals,buffer of float filtered,buffer of float scene,buffer of float coverage,int width,int height,float exposure,int filterEnabled,int mode) returns bool: Coverage compose.
- Temporal(buffer of int pixels,buffer of float geometry,buffer of float output,buffer of float previous,buffer of float previousGeometry,buffer of float scene,buffer of float camera,int revision,int enabled) returns bool: Temporal.

## Use dolphinGpuSignalVerifier

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.
dolphinGpuSignalVerifier sample = dolphinGpuSignalVerifier()
Console.Log("Created dolphinGpuSignalVerifier")
