Package limn.render3d.scene

package 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. Keep a hierarchy here when transforms nest; the guarantee worth knowing is that a declarative scene renders identically to the equivalent imperative draws.

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.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.
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
LightNode	A Node carrying a Light.
MeshNode	A Node that draws a GpuMesh with a Material.
Node	A node in the retained Scene3D graph: a local Transform3D plus children.
Scene3D	A retained 3D scene: a Node tree plus scene-wide ambient/exposure and an optional background.
Scene3D.MeshInstance	A mesh to draw, paired with its composed world transform.
