A 3D scene: a flat list of objects and lights with a background.

The scene has no scene graph; every object carries its own world-space transform. Compose hierarchies (such as articulated models) in application code by computing each object's transform before building the scene.

Fields

• :objects - list of ExRatatui.ThreeD.Object
• :lights - list of ExRatatui.ThreeD.Light
• :background - {r, g, b} clear color (defaults to black)
• :sky - optional gradient sky %{zenith: rgb, horizon: rgb, ground: rgb}, sampled by the raytrace pipeline; nil to use the flat background

Examples

iex> alias ExRatatui.ThreeD.{Scene, Object, Light, Mesh}
iex> scene = %Scene{
...>   objects: [%Object{mesh: Mesh.cube()}],
...>   lights: [Light.ambient({255, 255, 255}, 0.2)],
...>   background: {10, 10, 20}
...> }
iex> length(scene.objects)
