[Maya-Python] Re: numpy with maya and snow leopard
I have tried to use easy_install within maya to install it, but It is not building correctly (the same is true outside of maya too). what errors did you get when using easy_install? and if easy_install did not work, how did you get it to install? -chad --~--~-~--~~~---~--~~ http://groups.google.com/group/python_inside_maya -~--~~~~--~~--~--~---

[Maya-Python] Re: adding float array attributes to a node from a command
just a note, I had a chat with someone and it seems I could get the DataBuilder in a command from MPlug... also I had some mistake in initialize method. But please comment anyway if you have something to say, as I might come back with other problem with this thing. On Oct 25, 9:52 pm, Jakub Krompolc syntet...@googlemail.com wrote: hello, I`m working on python deformer plugin. It`s a node that will hold several arrays of float values. Those arrays are all under one compound attribute (set as array as well). I want the same workflow as Maya blendShape, so user will run a command and add another array when he wants. The deformer will then compute final result based on arrays that user added. First I have set both compound and values attributes as using arrayDataBuilder, but this only works under the node, not in the command. But the array creation in the node would need to be triggered by command somehow. What I`m doing now is trying to use MPlug in command using selectAncestorLogicalIndexwhich could create the data, but I`m getting different errors as if the array couldn`t be made - maybe auto- creation only works on single value elements? Then I have another idea, to make int attribute on a node with number of arrays. The node would always create one more array if the int value is the same as current size of array. The command would change this value to value+1 and so on. This way there would always be one free array for the command to use it and set values. But it sounds hacky... does anyone know the right way of doing this? this is part of the command, array creation part (which doesn`t work): #compound attr listPlug = OpenMaya.MPlug( deformNode, deformerName.list ) listSize = listPlug.numElements() #values attr valuesPlug = OpenMaya.MPlug( deformNode, deformerName.values ) valuesPlug.selectAncestorLogicalIndex( listSize, deformerName.list ) pointSize = 1000 #example, size of mesh points for i in range( pointSize ): valuesPlug.selectAncestorLogicalIndex( i, deformerName.values ) valuesPlug.setValue( 1.2 ) #some value --~--~-~--~~~---~--~~ http://groups.google.com/group/python_inside_maya -~--~~~~--~~--~--~---

[Maya-Python] Re: numpy with maya and snow leopard
hmmm... that does not look like fun. since numpy is compiled, i can
definitely see that there would be a problem copying libs compiled on
10.4 over to 10.6. i haven't looked at this problem yet myself, but
here are a few thoughts:
python2.6.1 is the default on snow leopard and it is 64 bit, which
makes compiling anything against it much more complicated. maya 2010
is still 32 bit, so you should not compile anything against the system
2.6 to use within 2010.
to get the best compatibility with maya, use mayapy to compile, rather
than compiling against the system and copying over. to do this,
create an easy_install for each maya installation, changing the top
line to the appropriate mayapy interpreter. our easy_install-maya2009
looks like this:
#!/usr/bin/env /Applications/Autodesk/maya2009/Maya.app/Contents/bin/
mayapy
# EASY-INSTALL-ENTRY-SCRIPT:
'setuptools==0.6c9','console_scripts','easy_install'
__requires__ = 'setuptools==0.6c9'
import sys
from pkg_resources import load_entry_point
sys.exit(
load_entry_point('setuptools==0.6c9', 'console_scripts',
'easy_install')()
)
not sure why the /usr/bin/env is necessary on osx (it's not on linux),
but for me it doesn't work without it. hope some of this helps.
