# Miscellaneous§

Besides the main collision detection and mesh generation related features, ncollide exposes a number of unclassified operations that are used internally by the library. Those operations are exported by the utils module. Here are listed some of the most useful operations:

Function Description
center(pts) Computes the center of the points pts.
circumcircle(a, b, c) Computes the circumcircle of the triangle a, b, c.
cov(pts) Computes the covariance matrix of the points pts.
is_point_in_triangle(...) Tests that a point is inside of a triangle.
sort3(a, b, c) Sorts in increasing order a set of three values.
triangulate(pts) Triangulates the points pts.
