Tools
Free browser tools for 360° panoramas and Gaussian splats — built because I needed them mid-project and the existing ones were worse. Nothing to install, nothing uploaded: your equirectangular JPEGs and your .ply and .sog files are decoded on your own machine and never leave it.
Available tools
Panorama Viewer
Split-view before-and-after for equirectangular panoramas
Drop in an equirectangular panorama and look around it. Load a second one and the view splits, so you can drag a divider across the same scene twice — two capture pipelines, two reconstruction algorithms, before and after. The second panorama rotates until it lines up with the first.
- — Runs entirely in the browser
- — Nothing is uploaded anywhere
- — WebGL, no dependencies
Splat Viewer
Split-screen before-and-after for Gaussian splats
Load two Gaussian splat reconstructions of the same scene and the frame splits in two. One camera drives both halves, so orbiting, panning and zooming move them together — drag the divider across the frame to see which run is actually better.
- — Runs entirely in the browser
- — Nothing is uploaded anywhere
- — PlayCanvas, WebGL 2
- — Reads .ply and .sog
What they're for
- Comparing two reconstruction, stitching or training runs on the same capture
- Before and after on denoising, HDR merging, upscaling, pruning or compression
- Checking an on-device result against a desktop or cloud one
- Site-progress and renovation captures of the same space over time
Why they run on your machine
Capture data is usually someone's building, someone's product or someone's unreleased scan. Uploading it to look at it is a bad trade, and it is not a trade these tools ask for: there is no server, no account and no analytics on file contents. That is also why they stay fast — nothing waits on a round trip.
Questions
Are these really free?
Yes. No account, no trial, no export watermark and no paid tier waiting behind the useful part. They exist because I needed them mid-project and the alternatives were worse.
Is anything I open uploaded?
No. Every tool here decodes your file in the browser and hands it straight to the GPU. There is no server to upload to — once the page has loaded, each tool keeps working with your network disconnected.
What do I need to run them?
A current browser on any desktop or phone. The panorama viewer needs WebGL; the splat viewer needs WebGL 2. Nothing to install.
Can I use them for client work?
Yes, commercial use included. They are tools, not a licence negotiation.
All of it came out of phone-captured spatial reconstruction work — that's also what I do for a living.
