java.lang.Object

com.bulletphysics.collision.narrowphase.SimplexSolverInterface

Direct Known Subclasses:

VoronoiSimplexSolver

public abstract class SimplexSolverInterface
extends Object

SimplexSolverInterface can incrementally calculate distance between origin and up to 4 vertices. Used by GJK or Linear Casting. Can be implemented by the Johnson-algorithm or alternative approaches based on voronoi regions or barycentric coordinates.
