Re: [Visualpython-users] Does Glowscript have numpy-like performance?

[Bruce S. <Bru...@nc...>]

I've now converted the VPython demo program gas.py to GlowScript:

http://www.glowscript.org/#/user/GlowScriptDemos/folder/Examples/program/HardSphereGas

To run the program, you need to have a WebGL-enabled browser and a
modern graphics card. For details, see the Help at glowscript.org.

As for speed, this is what I found:

VPython gas.py with 100 atoms, dt = 1e-5, no graphing: 100 iterations
= 1.1 seconds. This similar Glowsript program with same conditions:
100 iterations = 11.7 seconds. Presumably the big difference is the
Python numpy library, which runs at C speed, and which eliminates some
explicit loops.
