SCALE transformation function

Syntax

SCALE (transformation BY scale_factor)

Function

Return a transformation value equal to the transformation parameter with the position scaled by the scale factor.

Parameters

transformation Transformation expression that is to be scaled.

scale_factor Real-valued expression that is used to scale the transformation parameter value.

Details

The value returned is equal to the value of the input transformation parameter value except that the X, Y, and Z position components are multiplied by the scale factor parameter. The rotation components have their values unchanged.

Example

If the transformation x has the value:
(200, 150, 100, 10, 20, 30)
then executing the instruction:
SET y = SCALE(x BY 1.25)
results in the transformation y receiving the value:
(250, 187.5, 125, 10, 20, 30)
