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

```yh
external DolphinProjectOrthographic(Vector3 point, float yaw, float pitch, float pixelsPerUnit, float centerX, float centerY) returns dolphinProjection
```


## Use DolphinProjectOrthographic

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.
Vector3 point = Vector3(1.0, 1.0, 1.0)
float yaw = 1.0
float pitch = 1.0
float pixelsPerUnit = 1.0
float centerX = 1.0
float centerY = 1.0
dolphinProjection result = DolphinProjectOrthographic(point, yaw, pitch, pixelsPerUnit, centerX, centerY)
Console.Log("Inspect result in your debugger")

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.dolphin_projection3d__dolphinprojectorthographic"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

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

[[dependencies]]
package = "dolphin.projection3d"
version = "0.1.0"
path = "../../../dolphin/packages/projection3d"

[[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.projection3d--DolphinProjectOrthographic/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.
