"""Tiny threaded HTTP server for the three.js demos that fetch local files.
|
|
|
|
Why a sibling helper script instead of `python -m http.server`?
|
|
The stdlib SimpleHTTPServer is single-threaded; Chrome opens many parallel
|
|
connections (HTML + 9 script tags + FBX), the first eats the worker, the
|
|
rest time out with net::ERR_EMPTY_RESPONSE. ThreadingHTTPServer fixes it.
|
|
|
|
Usage:
|
|
python examples/three.js/server/serve-demo.py
|
|
open http://localhost:8765/examples/three.js/demos/05-skinned-realtime.html
|
|
