Maps, Data, and Charts - Bound for Great Things!
summary
A web SaaS that extrudes building footprints and imports interiors from Magic Plan uses Postgres/Java backend, Angular frontend, Node for packages, and three chart libraries while rendering 3D via Cesium. The team migrates from Google Earth and hits a reproducible visual artifact: intersecting translucent polygons produce a “snow” of black speckles on certain machines — consistently on several MacBook Airs (2011–new) — traced to fallback alpha transparency / driver behavior (likely Intel/WebGL). They collect test data and want a concise conformance test.
