PC.2 Point clouds viewer in CivilCraft 3D and plan

First pass in the lab: streaming nodes within a point budget, colour by RGB/height/class/intensity/residual. Headless software GL only, so the 55 fps target is not measured.

civil-points-09 2026-11-05: Eye-dome lighting (own shader, whole scene through a depth target), size attenuation (a point shader), a phone default (500 k, EDL off), and a plan raster that refines when you zoom in (a window raster after the zoom settles) are built and tested in the real page (tools/pointcloud-engine/browser.mjs 27/0). Real GPU on workstation11a (RTX 5070, Chrome): 2 M points drawn at about 100 fps with EDL and shrinking points, no frame gap over 17 ms (tools/pointcloud-engine/gpu-fps.mjs). A made-up site, not a real survey; 50 M points are the PC.1 scale run.
