LCC for Web Downloads

LCC Web SDK is a high-performance 3DGS web rendering library that loads and renders large-scale 3DGS scene data (.lcc / .lcc2 and more) in the browser, with interactions such as ray casting, collision queries, and clipping boxes. It integrates with both Three.js and Cesium, supports WebGL 2.0, WebGPU, and WebXR, and runs on mainstream browsers including Chrome, Safari, and Edge.
