Package: dolphin.lightlab | Status: source-declared

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

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

```yh
external class dolphinGpuFrameSample
```

- int sequence: Stores sequence as int.
- int flags: Stores flags as int.
- text sceneEffects: Stores scene effects as text.
- dolphinGpuTraffic traffic: Stores traffic as dolphinGpuTraffic.
- int wallMicros: Stores wall micros as int.
- int dropped: Stores dropped as int.
- list of dolphinGpuPassSample passes: Stores passes as list of dolphinGpuPassSample.
- dolphinGpuFrameSample(): Dolphin gpu frame sample.

## Use dolphinGpuFrameSample

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.
dolphinGpuFrameSample sample = dolphinGpuFrameSample()
Console.Log(Text.From(sample.sequence))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.dolphin_lightlab__dolphingpuframesample"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "dolphin.lightlab"
version = "0.1.0"
path = "../../../dolphin/packages/lightlab"

[[dependencies]]
package = "dolphin.materials"
version = "0.1.0"
path = "../../../dolphin/packages/materials"

[[dependencies]]
package = "dolphin.math"
version = "0.1.0"
path = "../../../dolphin/packages/math"

[[dependencies]]
package = "dolphin.spatial3d"
version = "0.1.0"
path = "../../../dolphin/packages/spatial3d"

```

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

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/dolphin.lightlab--dolphinGpuFrameSample/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


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