详细描述

Describes a line in 3D space. A line is positioned in space with an axis (a gp_Ax1 object) which gives it an origin and a unit vector. A line and an axis are similar objects, thus, we can convert one into the other. A line provides direct access to the majority of the edit and query functions available on its positioning axis. In addition, however, a line has specific functions for computing distances and positions. See Also gce_MakeLin which provides functions for more complex line constructions Geom_Line which provides additional functions for constructing lines and works, in particular, with the parametric equations of lines

构造及析构函数说明

◆ GLin() [1/3]

GLin.GLin ( )

Creates a Line corresponding to Z axis of the reference coordinate system.

◆ GLin() [2/3]

GLin.GLin ( GAx1 theA1 )

Creates a line defined by axis theA1.

◆ GLin() [3/3]

GLin.GLin	(	GPnt	theP,
		GDir	theV
	)

Creates a line passing through point theP and parallel to vector theV (theP and theV are, respectively, the origin and the unit vector of the positioning axis of the line).

成员函数说明

◆ Angle()

double GLin.Angle ( GLin theOther )

Computes the angle between two lines in radians.

◆ Contains()

boolean GLin.Contains	(	GPnt	theP,
		double	theLinearTolerance
	)

Returns true if this line contains the point theP, that is, if the distance between point theP and this line is less than or equal to theLinearTolerance..

◆ Direction()

GDir GLin.Direction ( )

Returns the direction of the line.

◆ Distance() [1/2]

double GLin.Distance ( GLin theOther )

Computes the distance between two lines.

◆ Distance() [2/2]

double GLin.Distance ( GPnt theP )

Computes the distance between <me> and the point theP.

◆ Location()

GPnt GLin.Location ( )

Returns the location point (origin) of the line.

◆ Mirrored() [1/3]

GLin GLin.Mirrored ( GAx1 theA1 )

Performs the symmetrical transformation of a line with respect to an axis placement which is the axis of the symmetry.

◆ Mirrored() [2/3]

GLin GLin.Mirrored ( GAx2 theA2 )

Performs the symmetrical transformation of a line with respect to a plane. The axis placement <theA2> locates the plane of the symmetry : (Location, XDirection, YDirection).

◆ Mirrored() [3/3]

GLin GLin.Mirrored ( GPnt theP )

Performs the symmetrical transformation of a line with respect to the point theP which is the center of the symmetry.

◆ Normal()

GLin GLin.Normal ( GPnt theP )

Computes the line normal to the direction of <me>, passing through the point theP. Raises ConstructionError if the distance between <me> and the point theP is lower or equal to Resolution from gp because there is an infinity of solutions in 3D space.

◆ Position()

GAx1 GLin.Position ( )

Returns the axis placement one axis with the same location and direction as <me>.

◆ Reversed()

GLin GLin.Reversed ( )

Reverses the direction of the line. Note: - Reverse assigns the result to this line, while - Reversed creates a new one.

◆ Rotated()

GLin GLin.Rotated	(	GAx1	theA1,
		double	theAng
	)

Rotates a line. A1 is the axis of the rotation. Ang is the angular value of the rotation in radians.

◆ Scaled()

GLin GLin.Scaled	(	GPnt	theP,
		double	theS
	)

Scales a line. theS is the scaling value. The "Location" point (origin) of the line is modified. The "Direction" is reversed if the scale is negative.

◆ SetDirection()

void GLin.SetDirection ( GDir theV )

Changes the direction of the line.

◆ SetLocation()

void GLin.SetLocation ( GPnt theP )

Changes the location point (origin) of the line.

◆ SetPosition()

void GLin.SetPosition ( GAx1 theA1 )

Complete redefinition of the line. The "Location" point of <theA1> is the origin of the line. The "Direction" of <theA1> is the direction of the line.

◆ SquareDistance() [1/2]

double GLin.SquareDistance ( GLin theOther )

Computes the square distance between two lines.

◆ SquareDistance() [2/2]

double GLin.SquareDistance ( GPnt theP )

Computes the square distance between <me> and the point theP.

◆ Transformed()

GLin GLin.Transformed ( GTrsf theT )

Transforms a line with the transformation theT from class Trsf.

◆ Translated() [1/2]

GLin GLin.Translated	(	GPnt	theP1,
		GPnt	theP2
	)

Translates a line from the point theP1 to the point theP2.

◆ Translated() [2/2]

GLin GLin.Translated ( GVec theV )

Translates a line in the direction of the vector theV. The magnitude of the translation is the vector's magnitude.
