zigltf

A minimal glTF 2.0 loader for Zig.

zigltf provides:

• Direct deserialization of the glTF 2.0 JSON schema
• External buffer loading
• Accessor resolution
• Primitive attribute slicing
• Scene graph iteration utilities

It is designed as a lightweight, engine-agnostic asset loading layer.

---

Design Goals

• No external dependencies
• Explicit buffer and accessor resolution
• Minimal interpretation beyond spec requirements

---

Features

• JSON schema mirror (GltfJson)
• External .bin buffer loading
• Accessor byte-range resolution
• Typed PrimitiveView attribute access
• Node iteration utilities (BFS and DFS)
• Scene root resolution

---

Not Included

• GPU upload
• Animation runtime
• Skinning
• Morph targets
• Embedded data URIs
• Extension interpretation
• Scene graph transform evaluation

---

Example

const zigltf = @import("zigltf");

const gltf = try zigltf.Gltf.init(raw, allocator, path);
defer gltf.deinit(allocator);

// Depth-First-Search iterator
if (gltf.roots()) |roots| {
    var it = roots;
    while (it.next()) |node| {
        // process node
    }
}
