Boracay, Philippines · one drone capture, two representations

Gaussian splat vs digital twin

The same capture of The Lind, Boracay, shown two ways from identical cameras. Drag the divider: on the left the 3D Gaussian splat (photoreal, view-dependent light), on the right the mesh digital twin reconstructed from it (solid, measurable, editable geometry).

Top-down

Straight down over the hotel blocks and pools: the twin's footprint lines up with the splat to the pixel.

Low oblique towards White Beach

Up close, the difference shows: the splat keeps the look of the place, the mesh keeps its shape.

What each is good for

3D Gaussian splat

  • Photoreal: reflections, foliage, soft light and fine texture as the drone saw them
  • Fast to make from drone photos or video, streams in a browser
  • Great for showing a place: tourism, real estate, storytelling
  • No real surfaces: hard to measure, edit or simulate

Mesh digital twin

  • Solid geometry: measure distances, areas, heights; run sightlines and shadows
  • Editable in Blender, Unreal, CAD; exportable to GLB / OBJ / USD
  • Base for planning, simulation, games and labelled datasets
  • Loses the photoreal look; noisy where the capture was thin

How it was made: the splat's Gaussian centres (with their colours) were filtered, turned into a surface with Poisson reconstruction, trimmed to where the capture has data, coloured from the nearest captured point, decimated to 280,000 triangles and finished in Blender with a simplified ground. Both renders use the same camera, so the slider compares like with like.
