Complementary Dynamics cpp

Public c++ code release for the SIGGRAPH Asia 2020 paper Complementary Dynamics by Jiayi Eris Zhang, Seungbae Bang, David I.W. Levin and Alec Jacobson.

Dependency

libigl
Bartels

Setup

Before running the code, you need to setup the following.
Compile static library libbartels with Bartels:

cd Bartles
mkdir build
cd build
cmake .. -Dbartels_USE_STATIC_LIBRARY=ON
make -j8

Compile static library libigl with libigl:

cd libigl
mkdir build
cd build
cmake .. -DLIBIGL_USE_STATIC_LIBRARY=ON
make -j8

Run

Run examples by ./complementary_dynamics ../examples/example/example.json (with example being one example in provided in examples folder). For instance, try running following command

./complementary_dynamics ../examples/sphere/sphere.json

all parameter for physical model is defined in examples\example.json. try tweaking parameter and see how it effects the result.

Here are examples running sphere in different physical model:

ARAP	Neohookean	StVK	CoRotational

Here are exampels running sphere with different Young's modulus:

YM = 5e6	YM = 7e5	YM = 2e5	YM = 5e4

Here are some more examples:

frog	fish	elephant
