Member Data Documentation

body_types

BodyType collision_detection::DistanceResultsData::body_types[2]

The object body type.

Definition at line 322 of file collision_common.h.

distance

double collision_detection::DistanceResultsData::distance

The distance between two objects. If two objects are in collision, distance <= 0.

Definition at line 311 of file collision_common.h.

link_names

std::string collision_detection::DistanceResultsData::link_names[2]

The object link names.

Definition at line 319 of file collision_common.h.

nearest_points

EIGEN_MAKE_ALIGNED_OPERATOR_NEW Eigen::Vector3d collision_detection::DistanceResultsData::nearest_points[2]

The nearest points.

Definition at line 316 of file collision_common.h.

normal

Eigen::Vector3d collision_detection::DistanceResultsData::normal

Normalized vector connecting closest points (from link_names[0] to link_names[1])

Usually, when checking convex to convex, the normal is connecting closest points. However, FCL in case of non-convex to non-convex or convex to non-convex returns the contact normal for one of the two triangles that are in contact.
