Project 3D points into an orthographic 2D view with an inspectable camera.

```yh
external thing dolphinOrthoCamera
```

- bool valid: Stores valid as bool.
- Vector3 focus: Stores focus as Vector3.
- float cyaw: Stores cyaw as float.
- float syaw: Stores syaw as float.
- float cpitch: Stores cpitch as float.
- float spitch: Stores spitch as float.
- float scale: Stores scale as float.
- float cx: Stores cx as float.
- float cy: Stores cy as float.
- dolphinOrthoCamera(Vector3 focus,float yaw,float pitch,float scale,float cx,float cy): Dolphin ortho camera.
- Project(Vector3 point) returns dolphinProjection: Project.
- Facing(Vector3 normal) returns float: Facing.

## Use dolphinOrthoCamera

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using dolphin.projection3d

// Project 3D points into an orthographic 2D view with an inspectable camera.
dolphinOrthoCamera sample = dolphinOrthoCamera(Vector3(1.0, 1.0, 1.0), 1.0, 1.0, 1.0, 1.0, 1.0)
Console.Log(Text.From(sample.valid))

```

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