### 2.0.0 (Apr 14, 2026)
## 2.0.0 (Apr 14, 2026)

LOD System (details coming soon)
Spark 2.0 is a major release that adds a Level-of-Detail (LoD) system for 3DGS, enabling huge worlds to be rendered on the web on any device, with progressive streaming, virtual splat paging, and higher precision storage. It remains mostly backward compatible with 0.1 apps.

### 0.1.10 (Oct 24, 2025)
### New features

- New `SparkRenderer` that supports rendering multiple LoD splat trees computed according to max splat counts, minimum screen-space size, and camera foveation. Also supports rendering splats from a virtual paging system, extended precision encoding. New options for custom render targets and overriding material properties including custom shaders and uniforms.
- Tunable LoD rendering: max splat count tunable with `SparkRenderer.lodSplatCount` and `.lodSplatScale`, minimum detail with `.lodRenderScale`, foveation parameters using `.coneFov0`, `.coneFov`, `.coneFoveate`, and `.behindFoveate`. Individual meshes tunable using `SplatMesh.lodScale`, `.coneFov(0)`, `.coneFoveate`, and `.behindFoveate`.
- New splat file format `.RAD` (RADiance field) that supports custom field encoding, columnar storage and compression, and chunked random access, enabling progressive loading and streaming of huge 3DGS scenes.
- Two 3DGS downsampling algorithms: `tiny-lod` for generating LoD splat trees on-demand in the browser after loading, and `bhatt-lod` for higher-quality LoD splat tree generation in an offline setting. Both algorithms can be run in the browser or from the `build-lod` cmdline tool.
- On-demand LoD splat creation using `new SplatMesh({ lod: true })` and `SplatMesh.createLodSplats`, and instant toggling between LoD and non-LoD versions of the splats using `SplatMesh.enableLod`.
- Virtual splat paging system `SplatPager` to preallocate GPU buffers shared across splat objects, loaded across the network in order prioritized by the viewpoint, managed in LRU fashion.
- High-precision splat encoding in `ExtSplats` that mirrors `PackedSplats` and alleviates most precision issues. High precision usage selectable using `SplatMesh.extSplats`,`SparkRenderer.pagedExtSplats`, and `.accumExtSplats`.
- Multiple viewport rendering using multiple `SparkRenderer`, generalizing viewport rendering to encompass different scenes, splats, and shader effects between renders.

### Enhancements

- Huge file loading support from `ReadableStream`, enabling multi-GB splat files from URLs or local drag-and-drop without first allocating a full `Uint8Array`.
- Chainable splat Dyno modifiers using `SplatMesh.objectModifiers` and `.worldModifiers` arrays.
- New `SparkXr` wrapper for AR / VR experiences

### Breaking changes

- Apps must now explicitly create a `SparkRenderer` and add it to the scene. Spark no longer automatically injects one because it would sometimes result in multiple renderers within the scene.
- Multiple viewpoints now use multiple `SparkRenderer` instances instead of `spark.newViewpoint()`, and sorting options are configured directly on each renderer.
- Spark 2.0 requires THREE.js r179 or newer, replaces `VRButton` with `SparkXr`, and replaces `SparkRenderer.getRgba()` / `.readRgba()` workflows with generator-based RGBA rendering.
- `OldSparkRenderer` and related `Old*` classes are available as temporary fallbacks for code that still depends on the 0.1 renderer model.

### Deprecations

- Deprecated the experimental stochastic sort-free rendering mode.
- Deprecated splat texture support for arbitrary per-splat RGBA texture profiles.
