Position Based Fluids

An implementation of Position Based Fluids by Macklin and Mueller.

This was my final project in CSCE 450: Computer Animation at Texas A&M with Dr. Shinjiro Sueda.

The base rendering code is based off of Dr. Sueda's code provided in class.

Build

• Only tested on Arch Linux
  • Does not work on Windows via WSL2 & WSLg due to CUDA-OpenGL interop not being implemented.
• Dependencies: CUDA, GLEW, GLFW, GLM
  • pacman -S cmake cuda cuda-toolkit glew glfw glm

Usage

• SPACE to toggle simulation
• Orbit controls with mouse
  • CTRL translate
  • SHIFT zoom
• Update simulation parameters in CUDA/Parameters.cuh and recompile. (runtime config wip)

TODO

These are things I wanted to implement for this project, but ran out of time before the deadline.

• Collision with surfaces defined via SDF
  • Mesh to SDF conversion
• Implement Yu and Turk's paper on particle fluid surface reconstruction
• Screen-space fluid rendering
