High Level Overview

Dependencies

OpenKittenCAD is built on the shoulders of giants.

I am a true believer that for a project to be maintainable in the long term we have to keep as little dependancies as possible. This project depends on the following dependancies

• Flex
• Bison
• OpenCascade
• VTK (Soon to be removed as a dependent)

⚠️ Note: Not listing any of the dependancies dependances!

Contributing

If you are wanting to contribute a good start is Roadmap. If you find a issue please open a github issue. If you wish to make a PR please open a github issue and link it with it. Unless its a change like grammar fix. There is still a lot of work to be done. I work full time so progress on the project may be "slow". :)
