详细描述

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.

Resolution()

static double GP.Resolution ( )

static

Method of package gp 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().

YOZ()

static GAx2 GP.YOZ ( )

static

ZOX()

static GAx2 GP.ZOX ( )

static

Identifies a coordinate system where its origin is Origin, and its "main Direction" and "X Direction" coordinates Y = 1.0, X = Z =0.0 and X direction coordinates Z = 1.0, X = Y = 0.0
