get_closest_element_id()

CollisionElementID ug::node_tree::Traverser_ProjectPoint::get_closest_element_id

(

)

after the distance of a point to the geometry has been determined, this funtion returns the id of the element closest to the point.

get_closest_element_type()

int ug::node_tree::Traverser_ProjectPoint::get_closest_element_type

(

)

returns the type of the element to which the closest distance was found.

0: invalid, 2: edge, 3: triangle
