fluidsim

Note: Development of this repo has stopped, and the refactored version has been migrated to FluidVisualization.

My implementation of Position-Based Fluid[1] (or more?) and infrastructures[2] for further use.

Requirements

• GLFW (3.3 or above)
• ImGui (1.84.1 or above, hard requirement)
• CUDA (11.4.1 or above)
• OpenVDB (8.1.0 or above)
• g++ only (I don't know why yet)

Usage

To build:

  $ make -j12

To test(after building):

  $ make test

TODO

• other mathematical part of PBF (for accuracy)
• normal reconstruction
• work as a blender plugin (for convenience)
• simple raytracing render, for caustics

... and other algorithms
