avila-gltf

glTF 2.0 / GLB Exporter - 100% Rust

Complete glTF 2.0 specification implementation for exporting 3D scenes.

Features

• GLB binary format: Single-file glTF with embedded buffers
• Full spec compliance: Buffers, BufferViews, Accessors, Meshes, Materials
• Automatic optimization: u16/u32 index selection, padding, min/max bounds
• PBR materials: Full PBR metallic-roughness workflow
• Tested: Validates with glTF validators

Example

use avila_gltf::{GltfExporter, ExportOptions};
use avila_mesh::{Scene, primitives};

// Create scene
let mut scene = Scene::new();
scene.add_mesh(primitives::cube(2.0));

// Export to GLB
let exporter = GltfExporter::new();
let glb_bytes = exporter.export_glb(&scene, &ExportOptions::default())?;

// Save to file
std::fs::write("model.glb", glb_bytes)?;

Advanced Options

let options = ExportOptions {
    asset_name: "My Model".into(),
    include_normals: true,
    include_uvs: true,
};

let glb = exporter.export_glb(&scene, &options)?;

Output Format

• GLB: Binary glTF 2.0 with embedded buffers
• Optimized: Minimal file size, GPU-ready buffers
• Compatible: Works with Three.js, Babylon.js, Unity, Unreal
