SparkJS - 3D Gaussian Splat Renderer

What it does

SparkJS provides a JavaScript runtime and helper APIs for rendering 3D Gaussian splats (point-based rendering) in web browsers. This skill documents core components (SparkRenderer, SplatMesh, PackedSplats/ExtSplats), editing tools (SDF-based edits), procedural generators, LoD workflows, and Dyno shader patterns — enabling agents to create, debug, and optimise high-performance splat visualisations integrated with Three.js.

When to use it

Use this skill when you need to load or display splat file formats (.spz, .splat, .rad, .ply), generate procedural splat geometry (grids, text, images), implement Level-of-Detail streaming for large scenes, author Dyno GPU shader blocks, or tune rendering performance for web and VR targets. It is appropriate for building demos, visualization tools, or interactive experiences that rely on splat rendering.

What's included

• Scripts: none detected in the repository snapshot (documentation and templates provided).
• References: links to upstream docs (https://sparkjs.dev/docs/) and Dyno API noted in the skill body.
• Instructions: quick-start HTML/module template, API examples for renderer and mesh construction, SDF-based editing patterns, runtime and pre-built LoD workflows, performance tuning tips, and Dyno shader examples.

Compatible agents

Best suited for agents that can author or execute JavaScript/Node workflows and provide code suggestions (Copilot, Claude Code, Copilot-type assistants). The skill includes code snippets for browser modules and Three.js integration.
