Struct ObjScene 

pub struct ObjScene {
    pub nodes: Vec<ObjSceneNode>,
    pub meshes: Vec<ObjMesh>,
    pub materials: Vec<ObjMaterial>,
}

A simple scene graph for OBJ scenes.

Fields

nodes: Vec<ObjSceneNode>

All nodes in the scene.

meshes: Vec<ObjMesh>

All meshes in the scene.

materials: Vec<ObjMaterial>

All materials in the scene.

Implementations

impl ObjScene

pub fn new() -> Self

Create an empty scene.

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

Add a mesh to the scene and return its index.

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

Add a material to the scene and return its index.

pub fn add_node( &mut self, name: &str, mesh_index: Option<usize>, transform: MeshTransform, ) -> usize

Add a node to the scene and return its index.

pub fn add_child(&mut self, parent_idx: usize, child_idx: usize)

Set a node as a child of another node.

pub fn flatten(&self) -> ObjMesh

Flatten the scene hierarchy into a single merged ObjMesh.

Each node’s mesh is transformed by the node’s local transform.

pub fn total_vertices(&self) -> usize

Total number of vertices across all meshes.

pub fn total_faces(&self) -> usize

Total number of faces across all meshes.

Trait Implementations

impl Clone for ObjScene

fn clone(&self) -> ObjScene

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjScene

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ObjScene

fn default() -> ObjScene

Returns the “default value” for a type.
