Move web/ to javascript/ and declare it via [tool.comfy] web. Rename the seven third-party bundles (playcanvas, spark, three.js, gsplat, OrbitControls, TrackballControls) to .mjs. Every reference to them is inside the HTML viewers, but ComfyUI auto-imports **/*.js under the web dir into the shared browser realm, so ~8MB of vendor code was being evaluated in the main page on every startup -- and with it 36 collision errors: document.body injection, document-level listeners, unguarded message listeners and self.onmessage writes. The importmap values, script srcs and three.module's internal ./three.core ref are rewritten to match. DisplayName becomes "GaussianPack": the namespace enforced on registerExtension names is derived from it, and "ComfyUI-GaussianPack" made that prefix invalid. The analysis extension is renamed to match. js/gaussian_preview.js hooked "PlyPreviewLoadGaussianPLYEnhance", a node id that appears nowhere in this repo, so the PLY dropdown auto-refresh had never run; it now targets LoadPLY and LoadPLYOutput, the two nodes that actually carry the ply_file widget. Guard its message listener on event.source. Asset seeding resolves the input directory through folder_paths.get_input_directory(), so it follows ComfyUI Desktop and --input-directory instead of writing into the code tree. comfy-test.toml moves to the current schema: [test.workflows] cuda (there is no "gpu" key -- the accelerator is named by backend, and the old spelling parsed to an empty list, so CUDA runners silently ran the full unfiltered set), an explicit [test.platforms] platforms allowlist (per-platform booleans are no longer supported), and the javascript level.
Library to convert gaussian splats between PLY and SPZ formats
Based on the original C++ library.
Installation
npm install spz-js
Example (Node.js)
import {
createReadStream,
readFileSync,
writeFileSync,
unlinkSync
} from 'fs';
import { Readable } from 'stream';
import path from 'path';
import {
loadPly,
loadSpz,
serializePly,
serializeSpz
} from 'spz-js';
// Helper function to load either SPZ or PLY files
const loadFile = async (file) => {
const extension = path.extname(file);
if (extension === '.spz') {
const fileBuffer = readFileSync(file);
return await loadSpz(fileBuffer);
} else if (extension === '.ply') {
const fileStream = createReadStream(file);
const webStream = Readable.toWeb(fileStream);
return await loadPly(webStream);
}
throw new Error(`Unsupported file extension: ${extension}`);
};
const gs = await loadFile("gs.ply"); // or gs.spz
const plyData = serializePly(gs);
writeFileSync("gs.ply", Buffer.from(plyData));
const spzData = await serializeSpz(gs);
writeFileSync("gs.spz", Buffer.from(spzData));
Example (Browser)
import {
loadPly,
loadSpz
} from 'spz-js';
const loadFile = async (url) => {
const response = await fetch(url);
const extension = url.split('.').pop();
if (extension === 'spz') {
const buffer = await response.arrayBuffer();
return await loadSpz(buffer);
} else if (extension === 'ply') {
return await loadPly(response.body);
}
throw new Error(`Unsupported file extension: ${extension}`);
};
