3D in matplotlib

One of the frustrating things about matplotlib is its lack of 3D plotting. If matplotlib were a mediocre library it wouldn' hurt. But it is a GREAT library and produces really good looking plots. So the lack of 3D plotting sometimes makes me want to go out and strangle somebody. There has however always been a furtive 3D plotting feature in matplotlib, and apparently, its being worked on some more. Yeehah! No more futzing with pyVtk.

Important links:
  1. Docs for 3D features
  2. Installing the svn code (that has all this goodness)

  1. badly written post..
    there is 3d support in matplotlib from 1.0, and there has been on svn for quite a while.

    mplot3d is now better integrated.

  2. Indeed, welcome progress in 3D plotting support in matplotlib has been made in the past year and a half since this post was written.

Python: Multiprocessing: passing multiple arguments to a function

Write a wrapper function to unpack the arguments before calling the real function. Lambda won't work, for some strange un-Pythonic reason.


import multiprocessing as mp def myfun(a,b): print a + b def mf_wrap(args): return myfun(*args) p = mp.Pool(4) fl = [(a,b) for a in range(3) for b in range(2)] #mf_wrap = lambda args: myfun(*args) -> this sucker, though more pythonic and compact, won't work p.map(mf_wrap, fl)

Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.

UPDATE:

The omnipresent anonymous asked:
Trying to enter sentence so that text forms the number three...any ideas?
The solution:
Type '3' using the text toolConvert to path using object->pathSize as necessaryRemove fillUngroupType in actual text in new text boxSelect the text and the '3' pathFlow the text
