Splataverse Sunshine Coast: Maroochydore

The Sunshine Coast Council's 2019 Maroochydore integrated mesh (I3S) converted to 3D Gaussian splats with the splataverse analytic mesh→3DGS converter. The converter uses a derived, hyperparameter-free density: one Gaussian lattice per face, with spacing set by the source texture resolution. The source has very fine facade texture (median leaf texel 0.79 cm), which makes it the best street-level (car-height) source in the splataverse collection.

Splat renders at 1.8 m eye height (1600×900, 75° FOV), 131–237M Gaussians drawn per view by the splataverse HLOD frustum renderer. Each camera was placed automatically from the splats. White areas are outside the captured area.

nodes / leaves	13,510 / 4,332 (LOD tree)
leaf texel (median)	0.79 cm
size	116 GiB (SPZ v3)
conversion	14.5 min wall, 13.75 CPU-hours
street render	131–237M Gaussians per 1600×900 view at sse 1 px

Layout

maroochydore_street/lod_index.json plus maroochydore_street/tiles/<k>/<n>.spz (SPZ v3, recentred per tile). Each index node lists its file, its world offset (add it to the tile's positions), its bounds, its Gaussian count, its geometric error in metres and its children. To render, refine nodes by screen-space error from roots down. The frame string gives the coordinate frame (Y-up, metres). layer.json / nodes.json are the original I3S layer and node metadata.
