Overview

Type:	Function
Available as of:	V1.0.3.0
Versions:	Current version

Task

Rotation of a point in the 3-dimensional space about the X axis.

Description

Carries out a rotation of the point represented by the position vector i_stV about the X axis using the angle i_lrAngle in an anti-clockwise direction. For this purpose, the angle i_lrAngle must be specified in degrees.

Interface

Input	Data type	Description
i_stV	ST_Vector3D	Position vector of the point to be rotated
i_lrAngle	LREAL	Angle by which the point is to be rotated

Output	Data type	Description
q_etDiag	GD.ET_Diag	General library-independent statement on the diagnostic. A value not equal to ET_Diag.Ok corresponds to an diagnostic message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnostic. q_etDiag = ET_Diag.Ok -> Status message q_etDiag <> ET_Diag.Ok -> Diagnostic message
