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>

Mesh storage. 网格存储。

textures: Arena<Texture>

Texture storage. 纹理存储。

objects: Arena<RenderObject>

Render-object storage. 渲染对象存储。

light: DirectionalLight

The single directional light of the scene. 场景中唯一的方向光。

Implementations

impl Scene

pub fn new() -> Self

Create an empty scene. 创建一个空场景。

Examples

示例

use he3d_core::{Material, Mesh, RenderObject, Rgb, Scene, Transform};

let mut scene = Scene::new();
let mesh = scene.meshes.insert(Mesh::triangle(1.0, 1.0)?);
let object = scene.spawn(RenderObject {
   mesh,
   texture: None,
   transform: Transform::default(),
   material: Material::new(Rgb::WHITE),
   visible: true,
});
assert!(scene.objects.contains(object));

pub fn spawn(&mut self, object: RenderObject) -> ObjectId

Insert a render object and return its handle. 插入一个渲染对象并返回其句柄。

Trait Implementations

impl Default for Scene

fn default() -> Self

Returns the “default value” for a type.
