3D Showcase

Default view is a stable inspect scene so you can orbit, hover, and read axes. Optional streams stay slow and opt-in — they no longer race off-screen.

Labeled axes + grids — readable X / Height / Y chrome
Hover pick — surface cell vs LiDAR point (tooltip)
Contours — isolines on the height field (toggle)
Optional: bounded cloud FIFO · smooth spectrogram strip (camera can follow scroll)

Production profiling: measure FPS with bun run build + bun run preview:examples (or examples production build), not the Vite dev server (dev incurs ~3× GPU overhead). Prefer a calm first paint; raise cloud size only when stress-testing.

Streams are off by default. Enable one at a time to demo FIFO or strip scroll (strip runs at display refresh for smooth motion).

Try: orbit · hover a ridge (surface) vs a sample (LiDAR) · toggle contours · then optionally enable strip scroll (display-rate, smooth). Axis labels use labelMode: 'auto' (GPU glyph atlas when available). Drag to orbit · Shift-drag to pan · Wheel to zoom · Double-click / Reset camera. Thin demos: point-cloud-3d / surface-3d. Profile production dist, not Vite dev.
