Loader-3d

一个用Rust编写的简单3D加载器。此项目不试图成为最快的3D库，它作为快速开始有趣（有趣）东西的简单库。目前，该项目支持Obj和glTF文件，但添加更多格式应该很简单。

用法

use l3d::prelude::*;

// Create an instance
let instance = LoadInstance::new()
    // Adds default loaders (gLTF and obj files)
    .with_default();

// Load file
match instance.load(LoadOptions {
    path: PathBuf::from("path/to/my/file.gltf.obj"),
    ..Default::default()
}) {
    // Single mesh
    Mesh(descriptor) => {
        // descriptor.vertices: Vec<[f32; 4]>,
        // descriptor.normals: Vec<[f32; 3]>,
        // descriptor.uvs: Vec<[f32; 2]>,
        // descriptor.tangents: Vec<[f32; 4]>,
        // descriptor.material_ids: Vec<i32>,
        // --- Mesh descriptors do not have a material list when they are part of a scene ---
        // descriptor.materials: Option<MaterialList>,
        // descriptor.meshes: Vec<VertexMesh>,
        // descriptor.skeleton: Option<SkeletonDescriptor>,
        // descriptor.bounds: AABB,
        // descriptor.name: String,
    }
    // A scene with meshes and a scene graph
    Scene(descriptor) =>  {
        // descriptor.materials: MaterialList,
        // descriptor.meshes: Vec<MeshDescriptor>,
        // descriptor.nodes: Vec<NodeDescriptor>,
        // descriptor.animations: Vec<AnimationDescriptor>,
    }
    // Error
    None(LoadError),
