Maya NPR Framework

The open-source non-photorealistic rendering framework for Maya

The Maya Non-photorealistic Rendering Framework (MNPR) is a direct 3D stylization framework developed as part of my PhD research in Real-time Watercolor Rendering of 3D Objects and Animation with Enhanced Control. It partially contains and supports the technology found in:

It proposes a direct stylization framework for Expressive Rendering, another common term for Non-Photorealistic Rendering (NPR), directly in the Maya viewport. This makes the system instantly familiar to artists accustomed to the software. The backend is developed using C++ and HLSL/GLSL, whereas the frontend is being handled through Python and MEL. 

The prototype framework has been open-sourced under the MIT License and it can be found at GitHub and NTU’s data repository. The professional version MNPRX is based upon this original work.
