Fast Mass-Spring System Simulator

A C++ implementation of Fast Simulation of Mass-Spring Systems [1], rendered with OpenGL. The dynamic inverse procedure described in [2] was implemented to constrain spring deformations and prevent the "super-elastic" effect when using large time-steps.

Dependencies

OpenGL, freeGLUT, GLEW, GLM for rendering.
OpenMesh for computing normals.
Eigen for sparse matrix algebra.

Building

You need to install OpenGL, GLEW and GLUT on your system to build. The rest of the dependencies will be automatically fetched by cmake during configuration.

To build, run the following commands from the root directory of the project:

mkdir build
cd build
cmake ..
cmake --build .

On Windows, you will likely need to specify the directories containing GLUT and GLEW in CMAKE_PREFIX_PATH so that cmake can find them.

cmake .. -DCMAKE_PERFIX_PATH:PATH=/path/to/libs

You will also need to copy the DLLs to the build directory if they are not available globally.
