I wanted to create an isometric view, but I couldn’t find a proper way to do it, so I had to copy and paste the `CameraHorizontalRotation` code from the related demo into my own project.  
Where can I find more information about `CameraHorizontalRotation`?

The `CameraHorizontalRotation` is defined in our example project `isometric_game_3d/code/`.

It literally just rotates the regular 2D camera, as you can see in the editor. There’s not much more to document 🙂

Follow our manual about [viewports](https://castle-engine.io/viewport_and_scenes), [cameras](https://castle-engine.io/camera) (in particular read " 3. Camera can have children, and be a child of other objects") and play with transformations and cameras to understand them.

Note that the project contains additional Pascal code to play with other `CameraHorizontalRotation.Rotation` values (since various rotations make sense), doing:

```delphi
  CameraHorizontalRotation.Rotation := Vector4(0, 1, 0, Pi / 4 + Pi / 2 * CameraRot);

```

It you’re not sure what this means, read [API docs of TCastleTransform.Rotation](https://castle-engine.io/apidoc/html/CastleTransform.TCastleTransform.html#Rotation).
