Struct FbxReader 

pub struct FbxReader<R: Read + Seek = BufReader<File>> { /* private fields */ }

Available on crate feature fbx-reader only.

FBX reader for binary FBX files.

Implementations

impl FbxReader<BufReader<File>>

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

Open an FBX file from a path, using default read options.

pub fn open_with_options<P: AsRef<Path>>( path: P, options: FbxReadOptions, ) -> Result<Self>

Open an FBX file from a path with explicit read options.

impl FbxReader<Cursor<Vec<u8>>>

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

Create an FBX reader from in-memory bytes, using default read options.

pub fn from_bytes_with_options( bytes: impl Into<Vec<u8>>, options: FbxReadOptions, ) -> Result<Self>

Create an FBX reader from in-memory bytes with explicit read options.

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

Read all meshes directly from in-memory bytes.

impl<R: Read + Seek> FbxReader<R>

pub fn new(reader: R) -> Result<Self>

Create a new FBX reader from a reader, using default read options.

pub fn new_with_options(reader: R, options: FbxReadOptions) -> Result<Self>

Create a new FBX reader from a reader with explicit read options.

The header itself is parsed under options, so the options cannot be changed after construction.

pub fn warnings(&self) -> &[FbxWarning]

Container-layout notices collected by the most recent read.

pub fn version(&self) -> u32

Get the FBX file version.

pub fn byte_order(&self) -> FbxByteOrder

Byte order selected by this file’s header endian marker.

pub fn options(&self) -> &FbxReadOptions

Read options this reader was constructed with.

pub fn read_nodes(&mut self) -> Result<Vec<FbxNode>>

Read all top-level nodes.

Safe to call more than once: per-document budgets restart here, so a second read of the same file behaves exactly like the first.

impl<R: Read + Seek> FbxReader<R>

pub fn read_scene(&mut self) -> Result<FbxScene>

Reads the supported hierarchy, materials, textures, and animation from FBX.

The result retains model names, local transforms, materialized mesh geometry (positions, normals, UVs), per-polygon material indices, Phong/Lambert materials, textures, and node-TRS animation. It intentionally omits FBX pivots, pre/post rotations, inheritance rules, cameras, and arbitrary metadata. It retains skin clusters, bind poses, blend-shape deltas, and local TRS animation.

use draco_io::FbxMemoryReader;

let bytes = std::fs::read("model.fbx")?;
let mut reader = FbxMemoryReader::from_bytes(bytes)?;
let scene = reader.read_scene()?;
assert!(!scene.root_nodes.is_empty());

impl<R: Read + Seek> FbxReader<R>

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

Read meshes from the FBX file.
