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 dolphinGpuSurfaceCache
```

- int primitiveCount: Stores primitive count as int.
- int geometryGeneration: Stores geometry generation as int.
- int wallMicros: Stores wall micros as int.
- bool addressesReady: Stores addresses ready as bool.
- dolphinGpuSurfaceCache(): Dolphin gpu surface cache.
- Begin(int primitiveCount,int capacity) returns bool: Begin.
- Record(text label,text symbol,int began,int gpu,int bytes): Record.
- Update(dolphinLightWorld world,int revision,int budget) returns bool: Update.
- Valid(int record) returns bool: Valid.
- Debug(dolphinGpuView view,int mode) returns bool: Debug.

## Use dolphinGpuSurfaceCache

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.
dolphinGpuSurfaceCache sample = dolphinGpuSurfaceCache()
Console.Log(Text.From(sample.primitiveCount))

```
