Computer Graphics C++ (cgcpp)

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

Supports

• Python 3.9, Boost 1.76.0 on Windows
• Python 3.10, Boost 1.80.0 on Windows
• Python 3.11, Boost 1.82.0 on Windows
• Python 3.12, Boost 1.85.0 on Windows
• Autodesk Maya 2023-2025 on Windows (Python 3.9 and Boost 1.76.0 in Maya 2023, Python 3.10 and Boost 1.80.0 in Maya 2024, Python 3.11 and Boost 1.82.0 in Maya 2025)
• SideFX Houdini 19.5-20.5 on Windows (Python 3.9 and Boost 1.76.0 in Houdini 19.5, Python 3.10 and Boost 1.80.0 in Houdini 20.0, Python 3.11 and Boost 1.82.0 in Houdini 20.5)

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"))
