[−][src]Module gltf::accessor

Accessors for reading vertex attributes from buffer views.

Basic usage

Visiting the accessors of a glTF asset.

for accessor in gltf.accessors() {
    println!("Accessor #{}", accessor.index());
    println!("offset: {}", accessor.offset());
    println!("count: {}", accessor.count());
    println!("data_type: {:?}", accessor.data_type());
    println!("dimensions: {:?}", accessor.dimensions());
}

Utility functions

Reading the values from the vec3 accessors of a glTF asset.

Note

The Iter utility is a low-level iterator intended for use in special cases. The average user is expected to use reader abstractions such as mesh::Reader.

let (gltf, buffers, _) = gltf::import("examples/Box.gltf")?;
for accessor in gltf.accessors() {
    match (accessor.data_type(), accessor.dimensions()) {
        (DataType::F32, Dimensions::Vec3) => {
            let buffer_index = accessor.view().buffer().index();
            let buffer_data = buffers[buffer_index].0.as_slice();
            let iter = Iter::<[f32; 3]>::new(accessor, buffer_data);
            for item in iter {
                println!("{:?}", item);
            }
        }
        _ => {},
    }
}
