Package limn.render3d.gltf

package limn.render3d.gltf

glTF 2.0 loading: GltfLoader reads .gltf or binary .glb into a neutral GltfModel of meshes, materials and node transforms (no GPU and no third-party parser), so the reading and decoding can run on a worker (the loadAsync forms are cancellable and report progress) and the upload happens later, inside a frame.

Package	Description
limn.render3d	Render-to-texture 3D: Graphics3D is both the facade a caller uses inside a frame and the SPI the backend installs, and around it sit the neutral resources a scene is made of: MeshData and TextureData built on any thread, their uploaded twins GpuMesh and GpuTexture, Camera with its controllers, Material, Light, and the RenderPass draws are issued into.
limn.render3d.scene	A retained scene over the imperative pass: Scene3D traverses a Node tree of MeshNodes and LightNodes, composes world transforms, gathers the lights, frustum-culls and issues the same draws a caller could issue by hand.
limn.render3d.shader	A neutral, typed shader IR: a material's surface is a SurfaceOutputs built from Expr nodes, and a backend's code generator walks that DAG to emit its own shading language, so the toolkit ships no GLSL, and a new target means a new generator rather than new materials.

Class	Description
GltfLoader	Loads a glTF 2.0 asset into a neutral GltfModel: no AWT, no GPU.
GltfModel	A parsed glTF 2.0 asset as neutral CPU data: a node hierarchy, meshes (as MeshData), metallic-roughness materials, and encoded texture images.
GltfModel.DecodedTextures	The model's texture images decoded to pixels, ready to upload: the CPU half of GltfModel.toScene3D(), separated so it can be done off the UI thread.
GltfModel.ImageDef	An encoded image (PNG/JPEG bytes), left encoded until GltfModel.decodeTextures().
GltfModel.MaterialDef	Metallic-roughness material; texture fields index GltfModel.textures() (-1 = none).
GltfModel.MeshDef
GltfModel.NodeDef
GltfModel.Primitive	One drawable range of a mesh with its material index (-1 = default).
GltfModel.SamplerDef	A glTF sampler, kept as the file's GL enums; -1 = unspecified.
GltfModel.TextureDef
