Re: Convex Decomposition with HACD in Blender

I'm not an Python or a Blender expert at all, so I don't know what's going on (maybe it's something I've messed up myself).

However following your instructions (python setup.py install --install-lib=~/.config/blender/2.71/scripts/addons/),
everything seems to work, until I try to enable the addon in the Blender's addons page.
It can't be enabled, and I get the following error:

Code:

Traceback (most recent call last):  File "./blender-2.71-linux-glibc211-x86_64/2.71/scripts/modules/addon_utils.py", line 299, in enable    mod = __import__(module_name)  File "~/.config/blender/2.71/scripts/addons/mesh_convex_decomposition.py", line 2, in     from hacd_decompose import decomposeImportError: ~/.config/blender/2.71/scripts/addons/hacd_decompose.so: undefined symbol: Py_InitModule4_64

I'm using Ubuntu 14.04 - 64 bit
Any idea ?

P.S. I didn't know that C++ code can be called from a Blender Python script.

[Edt:] SOLVED. I had to install libpython3-dev.
By default the C++ files were compiled by including /usr/include/python2.7.
By switching them to /usr/include/python3.4 made it work.

The reported error was not very explanatory .

Convex Decomposition with HACD in Blender

Hello!

I just took the time to create a first version of a HACD binding to Blender. Select the object you want to be decomposed and select "ConvexDecomposition" (hit Space to get the function prompt). It creates a new object for each created convex hull.

It is the work of one evening, so bugs are to be expected. You can post bugs and feature request here, on bitbucket or per Email.

UPDATE: i updated to the more recent version of HACD from googlecode!
