refineContactNormals()

int collision_detection::refineContactNormals	(	const World::ObjectConstPtr &	object,
		CollisionResult &	res,
		double	cell_bbx_search_distance = 1.0,
		double	allowed_angle_divergence = 0.0,
		bool	estimate_depth = false,
		double	iso_value = 0.5,
		double	metaball_radius_multiple = 1.5
	)

Re-proceses contact normals for an octomap by estimating a metaball iso-surface using the centers of occupied cells in a neighborhood of the contact point.

This is an implementation of the algorithm described in: A. Leeper, S. Chan, K. Salisbury. Point Clouds Can Be Represented as Implicit Surfaces for Constraint-Based Haptic Rendering. ICRA, May 2012, St Paul, MN. http://adamleeper.com/research/papers/2012_ICRA_leeper-chan-salisbury.pdf

Parameters

The	octomap originally used for collision detection.
The	collision result (which will get its normals updated)
The	distance, as a multiple of the octomap cell size, from which to include neighboring cells.
The	minimum angle change required for a normal to be over-written
Whether	to request a depth estimate from the algorithm (experimental...)
The	iso-surface threshold value (0.5 is a reasonable default).
The	metaball radius, as a multiple of the octomap cell size (1.5 is a reasonable default)
