43// Define a C preprocessor constant for a Scale factor to apply to
44// various dimensionless tests in the geometry routines which test
45// if a point is on a surface. This number is an effective thickness
46// of a surface divided by a relevant dimension, such as the radius of
47// a cylinder. The default value is 0.0001.
48#define SURFACE_PRECISION 0.0001

50// Define a C preprocessor constant for the maximum number of turns
51// allowed for a Helix, which is used in some of the geometry routines
52// to limit the size of for or while loops. The default value is 50.
