-# libigl example project

-A blank project example showing how to use libigl and cmake. Feel free and
-encouraged to copy or fork this project as a way of starting a new personal
-project using libigl.

-## See the tutorial first

-Then build, run and understand the [libigl
-tutorial](http://libigl.github.io/libigl/tutorial/).
-
-## Dependencies
-
-The only dependencies are STL, Eigen, [libigl](http://libigl.github.io/libigl/) and the dependencies
-of the `igl::opengl::glfw::Viewer` (OpenGL, glad and GLFW).
-The CMake build system will automatically download libigl and its dependencies using
-[CMake FetchContent](https://cmake.org/cmake/help/latest/module/FetchContent.html),
-thus requiring no setup on your part.
-
-To use a local copy of libigl rather than downloading the repository via FetchContent, you can use
-the CMake cache variable `FETCHCONTENT_SOURCE_DIR_LIBIGL` when configuring your CMake project for
-the first time:
-```
-cmake -DFETCHCONTENT_SOURCE_DIR_LIBIGL=<path-to-libigl> ..
-```
-When changing this value, do not forget to clear your `CMakeCache.txt`, or to update the cache variable
-via `cmake-gui` or `ccmake`.

 ## Run
 
-From within the `build` directory just issue:
+To run the program, simply execute the binary:

+## Usage
+The load files are in `sim-test/rigid-test/*/json`, generated by `sim-test/rigid-test/*/*.json.in`.
