This is a GPU-based cloth simulator implemented by CUDA. The algorithm is based on ARCSim.

• Fnet force output per node output
  • NOTE: Allowing remeshing to generate more than 10k nodes can significantly slow down the performance
• 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]
