Public Attributes
btScalar	m_convexEpsilon
btScalar	m_planarEpsilon
	used to determine if an edge or contact normal is convex, using the dot product
btScalar	m_equalVertexThreshold
	used to determine if a triangle edge is planar with zero angle
btScalar	m_edgeDistanceThreshold
	used to compute connectivity: if the distance between two vertices is smaller than m_equalVertexThreshold, they are considered to be 'shared'
btScalar	m_maxEdgeAngleThreshold
	used to determine edge contacts: if the closest distance between a contact point and an edge is smaller than this distance threshold it is considered to "hit the edge"
btScalar	m_zeroAreaThreshold
