This is a GPU-based cloth simulator implemented by CUDA. The algorithm is based on ARCSim.
- Changed exporting to include obstacles.
- Introduced a new command line flag (--no-export-obstacles) to disable the export of obstacle data during simulations.
- Improved the naming convention for saved frame files, making it more intuitive and easier to manage.
- Adjusted the replay function to accommodate the new naming convention.
For example, I used this plugin to bring the OBJs into Blender 3.6.

- OpenGL
- GLAD (already in lib directory)
- GLFW
- jsoncpp
- Eigen
- CUDA
Note: If you're using Windows, vspkg is recommended to install dependencies.
Run the following command in this directory:
mkdir build
cd build
cmake ..
make all
The simulator has 5 different modes. All the command mentioned should be run in this directory. Drop the --gpu parameter if you want CPU simulation.
Simulate and display according to a configuration file.
Note: Currently, the simulate mode is not working due to an OpenGL issue.
./build/ClothSimulator simulate [config_file] --gpu
For example:
./build/ClothSimulator simulate conf/sphere.json --gpu
Similar to simulate mode, but will save cloth mesh for every frame to output directory. You can also disable obstacle data export with the '--no-export-obstacles' flag.
./build/ClothSimulator simulate_offline [config_file] [output_dir] --gpu [--no-export-obstacles]
For example:
./build/ClothSimulator simulate_offline conf/sphere.json output/sphere --gpu [--no-export-obstacles]
Resume and display a halted offline simulation.
./build/ClothSimulator resume [output_dir] --gpu
Similar to resume mode, but will save cloth mesh for every frame to output directory. You can also disable obstacle data export with the '--no-export-obstacles' flag.
./build/ClothSimulator resume_offline [output_dir] --gpu [--no-export-obstacles]
Replay simulation result according to a output directiry. This mode has no GPU mode.
./build/ClothSimulator replay [output_dir]
