Computer Graphics C++ (cgcpp)

A universal solution for common needs in C++ in computer graphics software.

Supports

• Python 2.7, Boost 1.67.0 on Windows
• Python 3.9, Boost 1.76.0 on Windows
• Autodesk Maya 2019-2023 on Windows (Python 2.7 and Boost 1.67.0 in Maya 2019-2022, Python 3.9 and Boost 1.76.0 in Maya 2023)
• SideFX Houdini 19.0-19.5 on Windows (Python 2.7 and Boost 1.67.0 in Houdini 19.0, Python 3.9 and Boost 1.76.0 in Houdini 19.5)

Support for other platforms and other DCC applications may come later.

Features

• Build inside a docker container (isolated predictable environment)
• Call library C++ functions from Python
• Dynamically reload modified libraries (each new call reloads the library and alows it to be updated)
• Throw Python exceptions from C++

Installation

Install in your Windows Python virtual environment:

python -m pip install git+https://github.com/ababak/cgcpp.git

Build the examples

mkdir out
python -m cgcpp examples/source_exception --out ./out
python -m cgcpp examples/source_maya --out ./out --maya
python -m cgcpp examples/source_houdini --out ./out --houdini

Make sure you have Maya and Houdini versions installed in default locations that correspond to versions listed in CMakeLists.txt

Test built examples

Should throw AttributeError: Some error exception:

python -c 'import cgcpp;cgcpp.call(lib="out/lib_exception", func="call")'

Inside Maya:

import cgcpp
print(cgcpp.call(lib="out/maya_module", func="ls"))

Inside Houdini:

import cgcpp
print(cgcpp.call(lib="out/houdini_module", func="ls"))
