public final class GltfLoader

Loads a Mesh from a glTF 2.0 model so applications can render real authored geometry rather than only the built in Primitives. Both the binary container (.glb) and the JSON form (.gltf) are supported; for the JSON form, buffers must be embedded as data: URIs (external .bin side files are not fetched). The first triangle primitive of the first mesh is read.

The loader produces the engine’s standard VertexFormat.POSITION_NORMAL_TEXCOORD layout so the result drops straight into any built in Material:

• POSITION (required) is read as the vertex position.
• NORMAL is read when present; otherwise flat per-triangle normals are computed so lit materials still shade correctly.
• TEXCOORD_0 is read when present; otherwise zero texture coordinates are written.

Materials, textures, skinning and animation in the glTF are ignored by load – it is a geometry loader. Apply a Material (and a Texture loaded via the device) to the returned mesh as usual. To keep the whole file – every part, the materials, the skeleton and the animation clips – use loadScene(byte[]) and draw it with com.codename1.gaming.AnimatedModel.

Example:

byte[] glb = loadGlbBytes(); // bytes of a .glb model
Mesh mesh = GltfLoader.load(device, glb);
Material material = new Material(Material.Type.PHONG).setTexture(texture);
device.draw(mesh, material, modelMatrix);
