Fast Distance Computation Between a Point and Cylinders, Cones, Line-Swept Spheres and Cone-Spheres
Aurélien Barbier, Éric Galin · Journal of Graphics Tools · 2004
This paper presents algorithms for computing the minimal distance between a point and a cylinder, a cone, a line-swept sphere, and a cone-sphere. Some optimizations are provided when queries are performed along a line which may be useful for voxelization applications. Source code is available online.
