A glTF 2.0 scene: a collection of nodes and meshes.

Fields

nodes: Vec<GltfNode>

Scene nodes.

meshes: Vec<GltfMesh>

Scene meshes.

accessors: Vec<GltfAccessor>

Accessors.

buffer_views: Vec<GltfBufferView>

Buffer views.

animations: Vec<GltfAnimation>

Animations.

materials: Vec<GltfMaterial>

Materials.

cameras: Vec<SceneCamera>

Cameras.

lights: Vec<SceneLight>

Lights (KHR_lights_punctual).

Implementations

impl GltfScene

pub fn new() -> Self

Create an empty scene.

pub fn add_camera(&mut self, cam: SceneCamera) -> usize

Add a camera and return its index.

pub fn add_light(&mut self, light: SceneLight) -> usize

Add a light and return its index.

pub fn to_json_with_hierarchy(&self) -> String

Serialize the scene as a glTF 2.0 JSON string including cameras and lights.

Cameras are written in the cameras array. Lights use the KHR_lights_punctual extension.

pub fn add_mesh(&mut self, mesh: GltfMesh) -> usize

Add a mesh to the scene and return its index.

pub fn add_node(&mut self, node: GltfNode)

Add a node to the scene.

pub fn mesh_count(&self) -> usize

Return the number of meshes in the scene.

pub fn node_count(&self) -> usize

Return the number of nodes in the scene.

pub fn traverse_depth_first<F>(&self, visitor: F)

where F: FnMut(usize, usize, [f64; 3]),

Traverse the scene graph depth-first, calling visitor with (node_index, depth, accumulated_translation) for each node.

pub fn collect_mesh_primitives(&self) -> Vec<(&str, &GltfPrimitive)>

Collect all mesh primitives in the scene with their associated node names.

pub fn add_material(&mut self, mat: GltfMaterial) -> usize

Add a material and return its index.

pub fn add_animation(&mut self, anim: GltfAnimation) -> usize

Add an animation and return its index.

pub fn nodes_using_mesh(&self, mesh_idx: usize) -> Vec<usize>

Find all nodes that reference a given mesh index.

pub fn total_vertex_count(&self) -> usize

Return the total vertex count across all meshes.

pub fn total_triangle_count(&self) -> usize

Return the total triangle count across all meshes.

pub fn to_json(&self) -> String

Serialize the scene as a glTF 2.0 JSON string.

Accessor and bufferView entries are written as stubs (no binary buffer).

Trait Implementations

impl Default for GltfScene

fn default() -> Self

Returns the “default value” for a type.
