DX real-valued function

V+ Language Reference Guide

DX, DY, DZ real-valued function

Syntax

DX (location)

DY (location)

DZ (location)

Function

Return a displacement component of a given transformation value.

Parameter

location Transformation value from which a component is desired. This can be a function, a variable, or a compound transformation.

Details

These three functions return the respective displacement components of the specified transformation value.

NOTE: The DECOMPOSE instruction can also be used to obtain the displacement components of a transformation value. If the rotation components are desired, that instruction must be used. DECOMPOSE is more efficient if more than one element is needed and the location is a compound transformation.

Example

Consider a transformation start with the following components:
125, 250, -50, 135, 50, 75
The following function references will then yield the indicated values:
DX(start)         ;Returns 125.00
DY(start)         ;Returns 250.00
DZ(start)         ;Returns -50.00
