It does. Thank you, Alok and Jo!
Best,

I did not use it for soft plugins, it was more for a pure python
library. Some of the functions involved geometry operations like
line-line intersection, some ray tracing algorithms etc. For these
specific functions I used Cython to build extension and then used them
in my python modules. I mixed everything using cython. Some code was all
python just got converted. Some other code pure C functions. And some
was a mix (thourgh pyrex code).
You are right, basically the idea is to inject python code with some
steroids. For Softimage plugins, if I have huge data sets to work with
like point position arrays etc. I would rather use C++ API. But for all
other needs, specially concerning file browsing and other stuff, Python
provides an easy, fast and more maintainable code.
So it depends on your use case scenario what would be a better
implementation.
Also, if you have python functions and you just want to convert them to
C code, it will not always be fast, unless you type cast and take care
of a few other things, like porting all of your loops in C. You can find
a little more about this here : http://www.perrygeo.net/wordpress/?p=116
Also remember that though Cython Site says that you can use MinGW to
compile, I had some problems with it, so I finally switched to Visual
Studio compiler.
Hope that helps,
Cheers !!

Thanks for the replies, guys!
I stumbled across all this today, so I have no idea yet what and how
can be done. That's why I'm asking.
I do my operator-prototyping in JScript at the moment, and planned to
port it to C++ when they are fully working.
Yet the idea not having to do the port to C++ is appealing, of course.
Prototype in Python, compile when finished, and lean back...
Alok, did you just compile specific functions, or whole Softimage
plugins with it?
Would that be possible, compile all the usual SI callbacks for an
operator? There are many differences in the SI Scripting and C++ API,
after all.
A fact you have to deal with when porting from JScript to C++, too.
As I understand it, you rarely touch the C code generated by Cython,
right? You could, but mainly it's just a means to get to a fast
compile of a Python program.
Regarding UI widgets:
the idea is NOT to use PyQt, but somehow call those .net-windows-libs
from Cython somehow. Sounds complicated, though.

Hi Eugen,
I used cython. It is really cool. But to use it efficiently you have to
really optimize your pyrex code, also use strongly caste your data
type. I
think out of the box also it works pretty well for some less
complicated
function prototypes.
