Struct Scene 

pub struct Scene {
    pub meshes: Arena<Mesh>,
    pub textures: Arena<Texture>,
    pub objects: Arena<RenderObject>,
    pub light: DirectionalLight,
}

Owns meshes, textures, render objects, and the scene light. 拥有网格、纹理、渲染对象和场景光。

Resources live in Arenas; the scene exposes the arenas directly so callers can insert assets and get stable handles back. 资源存放在 Arena 中；场景直接暴露这些 arena，以便调用方可以插入资源并获得稳定的句柄。

Fields

meshes: Arena<Mesh>

textures: Arena<Texture>

objects: Arena<RenderObject>

light: DirectionalLight
