Gaussian Splat Tools

Free browser tools to view, convert, compress, clean and inspect 3D Gaussian splat captures in PLY, SPLAT, SPZ, KSPLAT and SOG, plus COLMAP reconstructions.

Gaussian Splat Viewer

Open and explore 3D Gaussian splatting captures in your browser. Reads PLY, SPLAT, SPZ, KSPLAT and SOG — nothing is uploaded.

Gaussian Splat Converter

Convert Gaussian splat captures between PLY, SPZ, KSPLAT and SPLAT, with the size and the losses of each target shown before you convert.

Gaussian Splat Compressor

Shrink a Gaussian splat capture by splat count, spherical-harmonic degree and container, with the output size shown as you drag.

Gaussian Splat Simplifier

Drop the Gaussians that contribute least to a capture and compare the result against the original side by side.

Gaussian Splat Cropper

Box-select part of a Gaussian splat capture with a live wireframe and splat count, then export only that region.

Gaussian Splat Cleaner

Remove floaters, invisible splats and blown-up Gaussians from a capture, with each pass counted and a before-and-after view.

Gaussian Splat SH Inspector

See what the spherical harmonics in a splat capture are doing: band energies, the scene at each degree, and one splat's colour over every view direction.

Gaussian Splat Statistics

Measure a Gaussian splat capture: splat count, spherical-harmonic degree, opacity and scale distributions, bounding box and estimated VRAM.

Gaussian Splat to Point Cloud

Convert a 3D Gaussian splat capture into a coloured PLY or XYZ point cloud that CloudCompare, MeshLab and Open3D read correctly.

Gaussian Splat to Mesh

Reconstruct an approximate polygonal surface from a Gaussian splat capture and export it as GLB, PLY, STL or OBJ.

Mesh to Gaussian Splat

Sample a 3D mesh into a Gaussian splat scene and export it as SPZ, PLY, SPLAT or KSPLAT.

Gaussian Splat Compare

Load two Gaussian splat captures side by side and compare them visually and numerically, including how far apart the geometry really is.

Gaussian Splat Coordinate Converter

Convert a Gaussian splat capture between the axis conventions of COLMAP, glTF, Unity, Unreal and Blender, spherical harmonics included.

COLMAP Viewer

Open a COLMAP sparse reconstruction and inspect the point cloud, the camera poses, the intrinsics and the reprojection statistics.

COLMAP Cleaner

Filter out bad points and weak images from a COLMAP reconstruction and download a valid model, ready for COLMAP or 3D Gaussian Splatting.

COLMAP to glTF Visualizer

Export a COLMAP reconstruction as glTF or GLB — sparse points, camera frusta and real glTF cameras at every photograph's pose.
