Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/BulletDynamics/ContactSolverInfoData.cs

A plain data container for physics solver configuration values adapted from Bullet. It declares public fields that hold tuning parameters for the contact solver such as damping, friction, time step, ERP/CFM settings, iteration counts and solver mode.
