GigaSplat Editor, Fork of SuperSplat for Experimental Features

In the fast moving world of Gaussian Splatting tools, SuperSplat has become the de facto standard for editing captures. But because it is open sourced and permissibly licensed, developers can extend it separately.

That is the origin of GigaSplat, a new experimental platform built on top of SuperSplat and released this month by its creator as a “laboratory for Gaussian editing.” Rather than competing with SuperSplat, the project positions itself as an idea engine, a space where new interactions, UX refinements, and creative utilities can be tested rapidly, with the explicit hope that PlayCanvas (which maintains SuperSplat) will fold successful features back into the core editor.

The developer has already shared the full codebase with PlayCanvas. GigaSplat is openly designed as a contribution to the broader tooling ecosystem, to be a sandbox where new ideas can be tried without the weight of full production integration.

The inaugural release introduces a broad set of utilities aimed squarely at real world cleanup, inspection, and comparison.

One of the most immediately useful tools is Isolated Splats Analysis, a system that detects floaters and other stray points with tuned parameters and real time feedback. GigaSplat also adds a Camera Presets system supporting up to ten saved viewpoints.

Model heavy pipelines gain a lift from Quick Model Switching and a “show only selected file” mode, while multi model alignment gets a dedicated Alignment Tool that uses shared control points for precise registration. A new Compare Feature lets users reference one model to locate and remove unwanted splats in another.

Selection workflows see a complete overhaul. A new Circle Select Tool creates a much smoother, more intuitive region selection experience, and a Move While Selecting modifier (Ctrl + Shift) allows users to reposition the model without breaking their active selection. Common quality of life shortcuts, Unselect All, Invert Selection, round out the set, while the File menu now includes Recent Projects and Recent Imports, bringing SuperSplat style fluidity to reopening scenes.

Then just a day later, GigaSplat pushed an even bigger update: Depth-Filtered Selection, which exposes the depth structure of the selection area. This makes it much easier to create local adjustments in the editor. Behind the interface, GigaSplat caches the full list of “candidate splats” within the 2D area, enabling instant refinement without rerunning the selection every time.

A new Selection Tools Options panel appears whenever users select splats, offering a Depth Histogram that visualizes how splats distribute along the z-axis, paired with dual range sliders for filtering by percentage or actual world space units. Users can choose between Live Filtering, which dynamically adjusts existing selections, or Static Filtering for future selections only.

GigaSplat’s creator emphasizes that the project isn’t a fork meant to compete; it’s intentionally porous, openly inviting PlayCanvas to integrate any useful pieces back into Supersplat. As GigaSplat continues releasing experimental features, it appears to be a fast moving R&D layer atop the most established editor in Gaussian Splatting today.

The developer is actively seeking feedback, feature ideas, and real world test cases as the platform evolves. You can try GigaSplat for free.
