Detailed Description

basic 3D point object.

Unlike 2D points, this is not a template. It is expected that users of this class are modeling 3D space and needing only modest accuracy, hence floats.

WARNING: the default constructor does NOT initialize the point to any particular value (such as (0, 0, 0) ). This is by design, so people can allocate large point3d_t arrays without paying a construction cost. Just be aware that this code:

    point3d_t p;

means that the value of p is undefined, and is probably quite large and random.
