Struct ObjReader 

pub struct ObjReader { /* private fields */ }

Available on crate feature obj-reader only.

OBJ format reader.

Reads vertex positions, texture coordinates, normals, and faces from OBJ files.

Implementations

impl ObjReader

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Open an OBJ file for reading.

pub fn from_bytes(bytes: impl Into<Vec<u8>>) -> Self

Create an OBJ reader from in-memory bytes.

pub fn read_from_bytes(bytes: &[u8]) -> Result<Mesh>

Read a mesh directly from in-memory bytes.

pub fn read_positions(&mut self) -> Result<Vec<[f32; 3]>>

Read all positions from the OBJ file.

pub fn read_mesh(&mut self) -> Result<Mesh>

Read a mesh with positions and faces (if present).

The mesh is automatically processed to match C++ Draco OBJ loader behavior: point IDs are deduplicated in face-traversal order, which ensures binary compatibility when encoding with sequential encoding (speed 10).

Trait Implementations

impl Debug for ObjReader

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

Formats the value using the given formatter.

impl PointCloudReader for ObjReader

fn read_points(&mut self) -> Result<Vec<[f32; 3]>>

Read point positions only (no faces or topology).

impl ReadFromBytes for ObjReader

fn from_bytes(bytes: &[u8]) -> Result<Self>

Create a reader from a complete file payload.

impl Reader for ObjReader

fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Open a file for reading.

fn read_meshes(&mut self) -> Result<Vec<Mesh>>

Read multiple meshes (a scene) from the file.

fn read_mesh(&mut self) -> Result<Mesh>

Read a single mesh from the file.
