The geometric processor package, called gp, provides an
implementation of entities used :
. for algebraic calculation such as "XYZ" coordinates, "Mat"
matrix
. for basis analytic geometry such as Transformations, point,
vector, line, plane, axis placement, conics, and elementary
surfaces.
These entities are defined in 2d and 3d space.
All the classes of this package are non-persistent.

| static Standard_Real | Resolution () |
| | In geometric computations, defines the tolerance criterion
used to determine when two numbers can be considered equal.
Many class functions use this tolerance criterion, for
example, to avoid division by zero in geometric
computations. In the documentation, tolerance criterion is
always referred to as gp::Resolution().
