Detailed Description

Filter class to test if two objects can collide based on their object layer. Used while finding collision pairs. Uses group bits and mask bits. Two layers can collide if Object1.Group & Object2.Mask is non-zero and Object2.Group & Object1.Mask is non-zero. The behavior is similar to that in e.g. Bullet. This implementation works together with BroadPhaseLayerInterfaceMask and ObjectVsBroadPhaseLayerFilterMask
