Expand description

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 to your Cargo.toml:

[dependencies.gltf]
version = "1"

Examples

Basic usage

Walking the node hierarchy.

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(),
        );
    }
}

Import function

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

let (document, buffers, images) = gltf::import("examples/Box.gltf")?;
assert_eq!(buffers.len(), document.buffers().count());
assert_eq!(images.len(), document.images().count());

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. Buffer and image data can then be imported separately using [import_buffers] and [import_images] respectively.

Re-exports

Modules

    Buffers and buffer views.
  • camera
    Cameras and their projections.
  • image
    Images that may be used by textures.
  • iter
    Iterators for walking the glTF node hierarchy.
  • khr_lights_punctual
    Support for the KHR_lights_punctual extension.

Structs

  • Accessor
    A typed view into a buffer view.
  • Animation
    A keyframe animation.
  • Buffer
    A buffer points to binary data representing geometry, animations, or skins.
  • Camera

    Binary glTF contents.
  • Gltf
    glTF JSON wrapper plus binary payload.
  • Image
    Image data used to create a texture.
  • Material
    The material appearance of a primitive.
  • Mesh
    A set of primitives to be rendered.
  • Node
    A node in the node hierarchy.
  • Primitive
    Geometry to be rendered with the given material.
  • Scene
    The root nodes of a scene.
  • Skin
    Joints and matrices defining a skin.
  • Texture
    A texture and its sampler.

Enums

  • Error
    Represents a runtime error.
  • Semantic
    Vertex attribute semantic name.
