 Hi again,

 most Maya tools rely on input selections to be made prior to executing
 a command working on the selection. Now, instead of doing that I'm
 looking for an easy way to invoke an interactive pick session from a
 function. I find bits and pieces in the API documentation, all of them
 looking pretty much over the top for this rather simple task.

 Anyone having a hint on how to tackle that? Thanks in advance, cheers!

 -André

  Hey folks,

  For those interested, Ryan and I finally wrapped up our book and (not

  I mostly wanted to post here to ask that, if anyone on this list happens
  to pick up a copy, please do get in touch with me regarding any errors you
  find! It turns out writing a book is really hard, so I'm sure there were
  plenty of things that made it in under the radar in the final crunch ;) I
  just want to make sure we have an opportunity to fix as many issues as
  possible for the second printing. Thanks!

[Maya-Python] Is it possible to write a HwShaderNode in Python?

2011-10-09 Thread Jan Lachauer 
Hello All,

for several days I'm now trying to implement a Hw Shader Node using
the Python API.

Starting with the most basic node possible, I took RobTheBloke's
BasicHwShader and removed everything leaving just the color attribute
( see his c++ example here:
http://nccastaff.bournemouth.ac.uk/jmacey/RobTheBloke/www/source/maya/BasicHwShader1.zip
)

The problem occurs in the glGeometry method.
The call
glFT.glDrawElements( prim, indexCount,
OpenMayaRender.MGL_UNSIGNED_INT, indexArray )
just crashes Maya.

You can view my python code here:
http://pastebin.com/DtLVVND6

Does anyone have a clue how this could work? Any help is greatly
appreciated, thank you!

All the best, jan

PS: the glGeometry method also takes a pointer-to-pointer argument for
the normalArrays, i was also wondering if it's possible to acces that
with the MScriptUtil in some way??? getFloat4ArrayItem and
getFloatArrayItem doesn't work...

[Maya-Python] MNurbsIntersector

2009-09-01 Thread Jan Lachauer 

Hello Everybody,

First: thank you for this very usefull mailinglist!!

Second: i want to work with the MNurbsIntersector class but I don't 
manage to get it right.

nurbIntersect = OpenMaya.MNurbsIntersector()

gives me the error:

# AttributeError: 'module' object has no attribute 'MNurbsIntersector' #

In C++ its just: MNurbsIntersector nurbIntersect;
(see: closestPointOnNurbsSurfaceCmd.cpp, and 
intersectOnNurbsSurfaceCmd.cpp)

Does anyone know how i can use it in the Python API?

Thank you.

All the best,
delaque
