glTF 2.0 loader

This crate is intended to load glTF 2.0, a file format designed for the efficient runtime transmission of 3D scenes. The crate aims to provide rustic utilities that make working with glTF simple and intuitive.

Installation

Add gltf version 0.15 to your Cargo.toml.

[dependencies.gltf]
version = "0.15"

Examples

Basic usage

Walking the node hierarchy.

# fn run() -> Result<(), Box<std::error::Error>> {
# use gltf::Gltf;
let gltf = Gltf::open("examples/Box.gltf")?;
for scene in gltf.scenes() {
for node in scene.nodes() {
println!(
"Node #{} has {} children",
node.index(),
node.children().count(),
);
}
}
# Ok(())
# }
# fn main() {
#    let _ = run().expect("runtime error");
# }

Import function

Reading a glTF document plus its buffers and images from the file system.

# fn run() -> Result<(), Box<std::error::Error>> {
let (document, buffers, images) = gltf::import("examples/Box.gltf")?;
assert_eq!(buffers.len(), document.buffers().count());
assert_eq!(images.len(), document.images().count());
# Ok(())
# }
# fn main() {
#    let _ = run().expect("runtime error");
# }

Note

This function is provided as a convenience for loading glTF and associated resources from the file system. It is suitable for real world use but may not be suitable for all real world use cases. More complex import scenarios such downloading from web URLs are not handled by this function. These scenarios are delegated to the user.

You can read glTF without loading resources by constructing the Gltf (standard glTF) or Glb (binary glTF) data structures explicitly.
