[MayaVi-users] getting mayamat.py and other comments

[<ho...@il...>]

Hi Prahbu!

One fast question: Where can I get mayamat.py? I was googling around but found 
nothing.

And now a few comments:

First let me say thanks for the wonderful program MayaVi.
At my institute I use python + Numeric and Scipy together with some C++ Code for 
simulating laser resonators. IDLE + dislin together with disipyl (for nice 2d plots and 
sometimes 3d plots) + MayaVi (for realy wonderfull data visualisation) builts a really 
wonderfull and powerfull enviroment for doing this (If somebody knows something 
simular in an other  (perhabs faster) GUI--> Let me know!!)  These three parts fits 
really together (after changing a few lines of Code) . Idle and MayaVi are based on TK 
and in the disipyl package (very nice wrapper for dislin) there is the tkdisipyl.Diddle 
class for using dislin interactive in IDLE, so one can really use them together  in one 
(IDLE) shell. I tryed many other things but found nothing better that gives you an free 
interactive scientific enviroment with "integrated" 2D and 3D plotting posibilitis. Perhaps 
if Scipy is finished (with integreated MayaVi and finished Chaco) we will have 
something similar.  
There is only one thing that disturbs me on MayaVi. The slow data transfer from IDLE 
to MayaVi via writing and reading vtkdata files. With dislin you can directly visualise 
data from Numeric arrays without first (slowly) writing them to files and then reading 
them again. This is very powerful if you  are manipulating large array data interactive, 
because you must have the data anyway in the computers memory. Now I was reading 
something about mayamat.py in the communication between Prabhu and Fernando 
Perez.  Perhabs this is what I searching for. The example:

from Numeric import *
import mayamat

def f(x, y):
    return sin(x*y)/(x*y)

x = arange(-5., 5.05, 0.05)
y = arange(-5., 5.05, 0.05)
v = mayamat.surf(x, y, f)

If mayamat.surf send the data direct to MayaVi (or better say vtk) this would be 
wonderfull for me.

cheers

Marco
