Soft Body Simulation using eXtended Position Based Dynamics\n\n## Overview\n\nAcademic prototyping project for soft body simulation using XPBD.\nDifferent constraint types will be implemented \nusing [Eigen](https://eigen.tuxfamily.org/index.php?title=Main_Page) for matrix computations and [libigl](https://libigl.github.io/) for visualization and \nuser interaction.\n\n### Short term roadmap\n\n#### Constraint types\n- edge length\n- tetrahedral volume\n- fem based\n\n![Bar simulation example](./doc/bar-fem-xpbd.gif)\n![Cloth simulation example](./doc/pbd-simple-cloth-example.gif)\n![Bunny geometric simulation example](./doc/bunny-pbd-edge-length.gif)\n\n## Dependencies\n\n- C++17 compiler\n- [libigl](https://libigl.github.io/)\n\n[libigl](https://libigl.github.io/) is included in the project using CMake's FetchContent and pulls in [Eigen](https://eigen.tuxfamily.org/index.php?title=Main_Page), [glfw](https://www.glfw.org/), [Dear ImGui](https://github.com/ocornut/imgui) and [TetGen](http://wias-berlin.de/software/index.jsp?id=TetGen\u0026lang=1) with it.\n\n## Building\n\n```\n# Download repository\n$ git clone https://github.com/Q-Minh/position-based-dynamics\n$ cd position-based-dynamics\n\n# Configure and build project\n$ cmake -S . -B build\n$ cmake --build build --target pbd --config Release\n\n# Run the program\n$ ./build/Release/pbd.exe\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fq-minh%2Fposition-based-dynamics","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fq-minh%2Fposition-based-dynamics","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fq-minh%2Fposition-based-dynamics/lists"}
