Crate geogram_predicates

Geogram Predicates

A crate for rust interoperability with geograms robust predicates; via cxx.

Functions

• det_3d
  Computes the sign of the determinant of a 3x3 matrix formed by three 3D points.
• det_4d
  Computes the sign of the determinant of a 4x4 matrix formed by four 4D points.
• geo_sgn
  Gets the sign of a value.
• in_circle_2d_SOS
  Tests whether a point is in the circum-circle of a triangle.
• in_sphere_3d_SOS
  Tests whether a point is in the circum-sphere of a tetrahedron.
• initialize
  Needs to be called before using any predicate.
• orient_2d
  Computes the orientation predicate in 2d.
• orient_2dlifted_SOS
  Computes the 3d orientation test with lifted points, i.e the regularity test for 2d.
• orient_3d
  Computes the orientation predicate in 3d.
• orient_3dlifted_SOS
  Computes the 4d orientation test with lifted points, i.e the regularity test for 3d.
• points_are_identical_2d
  Tests whether two 2d points are identical.
• points_are_identical_3d
  Tests whether two 3d points are identical.
• show_stats
  Displays some statistics about predicates, including the number of calls, the number of exact arithmetics calls, and the number of Simulation of Simplicity calls.
• terminate
  Needs to be called at the end of the program.
