A dolphin affine3 record carrying a, x.

Last updated: 2026-09-09

Package: dolphin.spatial3d | Status: source-declared

Tags: cpu, dolphin, dolphin.spatial3d, method, source-example, spatial3d, thing

Work with Vector3, axis-aligned boxes, containment, and bounded ray intersections.

```yh
external thing dolphinAffine3
```

- float a: Stores a as float.
- float x: Stores x as float.
- dolphinAffine3(): Dolphin affine3.
- Direction(Vector3 v) returns Vector3: Direction.
- Point(Vector3 v) returns Vector3: Point.

## Use dolphinAffine3

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

Verification: type checked

```yh
using dolphin.spatial3d

// Work with Vector3, axis-aligned boxes, containment, and bounded ray intersections.
dolphinAffine3 sample = dolphinAffine3()
Console.Log(Text.From(sample.a))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.dolphin_spatial3d__dolphinaffine3"
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.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.spatial3d--dolphinAffine3/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## dolphinAffine3.Direction

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

Verification: type checked

```yh
using dolphin.spatial3d

// Direction.
dolphinAffine3 instance = dolphinAffine3()
Vector3 argument_v = Vector3(1.0, 1.0, 1.0)
Vector3 result = instance.Direction(argument_v)
Console.Log("Inspect result in your debugger")

```

## dolphinAffine3.Point

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

Verification: type checked

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