Last updated: 2026-09-09

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 dolphinGpuSpatialResolver
```

- dolphinGpuSpatialResolver(): Dolphin gpu spatial resolver.
- Resolve(buffer of int pixels,buffer of float geometry,buffer of float history,int width,int height,float exposure,bool denoise) returns bool: Resolve.
- ResolveWithTone(buffer of int pixels,buffer of float geometry,buffer of float history,int width,int height,float exposure,bool denoise,int tone) returns bool: Resolve with tone.

## Use dolphinGpuSpatialResolver

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

```

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

## dolphinGpuSpatialResolver.Resolve

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

argument_pixels.Resize(8)
buffer of float argument_geometry

Console.Log(Text.From(result))

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