Trimesh python library usage on Windows

[Nic Sievers]

Hi, 

How would you be able to use a library such as Trimesh in Maya 2019, perhaps 2020?   Seems to be a pure python library.  

https://github.com/mikedh/trimesh

I did install trimesh via pip and added  PYTHONPATH = C:\python_27_amd64\files\Lib\site-packages.   But there is a runtime error (attached pic) importing in Maya which based on output is numpy related.   I did try reinstalling numpy but perhaps numpy has to be compiled in the same visual studio as Maya?  

I did see some mentions on this forum of using mayapy.exe pip.   Would that install a correct version of numpy?

thanks,

Nic

Even if trimesh is pure python, it lists alot of compiled requirements 

https://github.com/mikedh/trimesh/blob/master/setup.py#L30

So that means the deps also need to be compiled for that specific Maya 

thanks,

Nic

Thanks for the confirmation Justin.   I looked more into those extra libraries.   Numpy seems to be the only critical one, the others seem to be for added features if you want to use them.

Anyway, today I did end up finding a precompiled version of numpy and scipy for Maya 2018 that also works for 2019.  I have visual studio 2017 installed.  It looks like maybe you can compile to older build targets, is that correct?  So I could build them in VS 2017 for VS 2015, a version that will work with Maya 2019?

cheers
