OpenLiDARViewer v0.4.6

A redesigned, icon-driven interface, standard CAD-style views, and a GPU terrain-compute path — all still browser-native, local-first, nothing uploaded.

Highlights

• Six standard views + parallel projection — snap the camera straight at a face with Top / Bottom / Front / Back / Left / Right, and toggle an orthographic (parallel) projection that removes perspective so walls and floors read flat for measuring. Lives beside the Orbit / Walk / Fly controls.
• Icon-driven tool surfaces — the bottom dock, the measurement toolbar, the Layers list, and the Export panel get a consistent line-icon set, each keeping its visible text label. Inspect and Probe are drawn as distinct tools. A full-screen toggle sits in the header. On phones, every panel folds into one bottom sheet with View / Analyse / Layers tabs, and the measurement tools reflow into a left-edge rail.
• GPU terrain compute (equivalence-gated) — terrain derivative and scatter passes can run on WebGPU, but the CPU stays the reference: the GPU path must pass a per-session equivalence probe before it is trusted, and falls back to the CPU silently otherwise. Correctness first, speed where it is proven.
• Interior floor plan — experimental PREVIEW — the wall trace is rebuilt from an explicit wall graph with flood-fill room segmentation and classified doorways, and a "Floor plan confidence" summary reports rooms, walls, openings, and the share of wall evidence that was interpolated. It is an approximate sketch for inspection, not a measured floor plan.
• Design pass — the Analyse verdict (Good / Preview / Limited / Blocked) is the unmistakable hero of the panel, the stacked side panels read in two tiers of emphasis, typography is quieter, and the mobile layout reflows for thumb-friendly targets. Dark, Light, and High-contrast themes are checked for WCAG AA contrast.
• Map sheet & honest labels — the printable contour map sheet no longer overlaps its title with the legend on long filenames, the contour-interval unit matches the scale bar (m / ft), and an ungeoreferenced sheet drops the E/N graticule and north arrow rather than implying a compass frame it does not have. Several label-vs-value drift fixes land alongside it.

Polish

• The streaming loader shows a determinate resident-node progress bar instead of indeterminate text.
• "Solo" in the Layers list is disabled when only one class is present.
• The ?debug overlay labels the load total as wall-clock time, reports the CPU / GPU terrain compute path, and no longer prints a misleading "0 draw calls" on backends that do not report it.
• Floor-plan export options (wall snapping, adaptive band) get a small UI; the preview stays an experimental PREVIEW.
• Input-escaping hardening across the new icon controls — labels never carry markup; only trusted static icons are injected.

Measurement and the floor-plan preview are for visual inspection and research, not survey-grade use. Treat any output as survey-grade only after validating it against survey-grade data and procedures.
