CGAL 5.0.3 - Shape Detection
EfficientRANSACTraits Concept Reference

Definition

A concept that describes the set of types required by the CGAL::Shape_detection::Efficient_RANSAC and all RANSAC shape classes.

To avoid copying potentially large input data, the shape detection class CGAL::Shape_detection::Efficient_RANSAC will work on the input data directly and no internal copy will be made. For this reason, the input data has to be provided in form of a random access iterator. Point and normal property maps have to be provided to extract the points and the normals from the input.
