So, I've been working on a simple physics system, and have gotten to the
point where passing around a tuple just isn't cutting it. Can anybody
suggest a good 2D vector implementation?This thread came up sometime last
year, and several implementations were put forward.
If you're happy to put all of your vectors into a single numpy/numeric
array, that is the fastest approach.
CGKit (http://cgkit.sourceforge.net/) is a C extension which is the fastest
vector-is-an-object implementation. Unless things have changed recently
though, this library is a nightmare to compile and install.
For pure Python, the fastest implementation is my euclid module:

comparison results were posted in the previous thread).
Cheers
Alex.
