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 dolphinGpuHybridComposer
```

- dolphinGpuHybridComposer(): Dolphin gpu hybrid composer.
- Compose(buffer of int flags,buffer of float geometry,buffer of float rawIndirect,buffer of float gathered) returns bool: Compose.

## Use dolphinGpuHybridComposer

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

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.dolphin_lightlab__dolphingpuhybridcomposer"
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--dolphinGpuHybridComposer/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## dolphinGpuHybridComposer.Compose

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

Verification: type checked

```yh
using dolphin.lightlab

// Compose.
dolphinGpuHybridComposer instance = dolphinGpuHybridComposer()
buffer of int argument_flags
argument_flags.Resize(8)
buffer of float argument_geometry
argument_geometry.Resize(8)
buffer of float argument_rawIndirect
argument_rawIndirect.Resize(8)
buffer of float argument_gathered
argument_gathered.Resize(8)
bool result = instance.Compose(argument_flags, argument_geometry, argument_rawIndirect, argument_gathered)
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.
