Open-source node system framework, to change your algorithmic code into useful tools to create much more complicated simulations!

ZENO is an open-source, Node based 3D system able to produce cinematic physics effects at High Efficiency, it was designed for large scale simulations and has been tested on complex setups. Aside of its simulation Tools, ZENO provides necessary visualization nodes for users to import and run simulations if you feel that the current software you are using is too slow.

Integrated Toolbox, from volumetric geometry process tools (OpenVDB), to state-of-art, commercially robust, highly optimized physics solvers and visualization nodes, and various VFX and simulation solutions based on our nodes (provided by .zsg file in graphs/ folder).

Go to the release page, and click Assets -> download zeno-windows-20xx.x.x.zip (zeno-linux-20xx.x.x.tar.gz for Linux).

Then, extract this archive, and simply run 000_start.bat (./000_start.sh for Linux), then the node editor window will shows up if everything is working well.

Apart from the GitHub release page, we also offer binary download from our official site for convinence of Chinese users: https://zenustech.com/d/

There are some example graphs in the misc/graphs/ folder, you may open them in the editor and have fun! Hint: To run an animation for 100 frames, change the 1 on the bottom-right of the viewport to 100, then click Run. Also MMB to drag in the node editor, LMB click on sockets to create connections. MMB drag in the viewport to orbit camera, Shift MMB to pan camera. More details are available in our official tutorial and my video tutorials.

If you find the binary version didn't worked properly or some error message has been thrown on your machine, please let me know by opening an issue on GitHub, thanks for you support!

To build ZENO from source, you need:

• GCC 9 or MSVC 19.28 , and CMake 3.16 to build ZENO.
• Qt 5.14 to build the ZENO Qt editor.
• (Optional) TBB for parallel support.
• (Optional) OpenVDB for volume nodes.
• (Optional) Eigen3 for solver nodes.
• (Optional) CGAL for geometry nodes.
• (Optional) CUDA 11.6 for GPU nodes.

Hint: WSL is not recommended because of its limited GUI and OpenGL support.
