What it is

The 3D visualization engine for AMap (Alibaba) — extruded buildings, animated heatmaps, scan effects, scatter and arc layers composed over the AMap tile base.

What I worked on

Polygon extrusion layer with data-driven height and color.
Animated scan / sweep overlays.
Camera path scripting for showcase demos.

The demo above

Pure Three.js recreation of the Loca extrude pattern — height-driven hue ramp, edge wireframes, an orbital camera and a ground sweep bar. No AMap SDK, no API key.
