Installation
Lets say you already tried:
pip install assimpcy
And that failed or you want to make changes to the code or recompile the extension with a different version of the Assimp library, so you will compile from the sources.
- You will need:
Cmake 3
Microsoft Visual Studio 2017+ for Windows or Gcc for Linux and Mac (Clang might work too).
Download AssimpCy from:
https://github.com/jr-garcia/AssimpCy
And extract the zip package (or clone the repository with Git).
Download Assimp from the official page (minimum version 5.0.1):
Compile Assimp with the next options for cmake:
-DBUILD_SHARED_LIBS=OFF -DASSIMP_INCLUDE_INSTALL_DIR=assimpcy_folder/files/include -DASSIMP_LIB_INSTALL_DIR=assimpcy_folder/files/lib
Replace
assimpcy_folder
with the path where AssimpCy was extracted / cloned.Compile and install Assimp with:
make make install
You should end up with Assimp headers in
assimpcy_folder/files/include
and static versions of 3 libraries inassimpcy_folder/files/lib
:libassimp, libIrrXML, libzlibstatic
Install Cython and Numpy with:
pip install cython==0.29.24 numpy==1.21.4
Note
The versions specified are the ones used to build the wheels stored at Pypi.
You are free to try older or newer versions of the packages listed above, if available.
Build AssimpCy by executing, from its folder:
python setup.py build_ext
If setup.py can’t find the headers, specify them manually:
python setup.py build_ext -I'path/to/assimp/headers' -L'path/to/library/'
Attention
If you get an error saying:
Cannot open include file: 'types.h':
It means that setup.py is not finding the Assimp headers. Make sure that there is a folder called
include
in the AssimpCy files folder or in a path that your compiler can find.Finally, to install the package, run:
python setup.py install
Check basic_demo.py in AssimpCy folder for a simple example or read Usage.
