VISGSim

VISGSim is a GPU-based real time cloth simulator.

Contributions

• A unified streaming pipeline for time integration and collision handling
• Unified collision handling: we present a parallel, integrated collision detection and response algorithm - Position projection and inelastic collision response force
• A new strategy of expanding bounding box(aabb) for the triangle (caused by our collision detection and response strategy)
• Maximizing Parallelism in the construction of BVHs

Here is a Demo.

• 12367 vertices
• intel core i5 and GTX 960
• nearly 1000 FPS

Operations

• space - start or stop the simulation
• 'W'/'w' - down in the axis '-y'
• 'S'/'s' - up in the axis 'y'
• 'X'/'x' - snapshot
• press left and drag to rotate
• press middle and drag to scale
• press right and drag to drag mass

Realated papers

• GPU-based Real-time Cloth Simulation for Virtual Try-on
• Maximizing Parallelism in the Construction of BVHs, Octrees, and k-d Trees
• Contact-Aware Matrix Assembly with Unified Collision Handling for GPU-based Cloth Simulation

Compile

Use cmake to compile it and check CUDA_SEPARATE_COMPILATION.

following is a simple build script for windows

git clone --recursive http://github.com/sutongkui/simulator
# notice: choose your own generator
cmake -G"Visual Studio 15 2017 Win64" -H".\simulator" -B".\simulator\build" -DCMAKE_INSTALL_PREFIX=install
cmake --build ".\simulator\build" --config "RelWithDebInfo" --target INSTALL
# generated files should be in install dir
dir install/bin

or you can use cmake-gui to do the job in an interactive way.
