Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/BulletCollision/ISimplexSolverInterface.cs

Interface for a simplex solver used by the Bullet collision detection port. It declares methods to manage simplex vertices, query closest points, backup/restore state, and retrieve simplex contents and counts for distance computations.
