Twirl3D-Operator  Example 

This operator performs a Twirl-effect to an image or 3d-temp-buffer
along a selected axis.

Parameters

Name        Possible Values/Unit            Description

Input       STREAM, TEMP1, ..., TEMP8,      input buffer
            TEMP3D1, ..., TEMP3D4
Ouput       STREAM, TEMP1, ..., TEMP8,      output buffer
            TEMP3D1, ..., TEMP3D4
TRender     ON, OFF                         indicate that the transformed 3d-temp-buffer
                                            is used for the last time and can be modified
                                            directly to conserve both memory and time
Axis        X, Y, Z                         axis to rotate around
Radius      pixels                          twirl-radius
Amount      degress                         twirl amount, very large values
                                            like 1000 are allowed
Power       float                           parameter describing the local
                                            deformation, large values like 6 concentrate
                                            the deformation around the centre of the circle
OriginX,    pixels                          centre of the effect
OriginY,    pixels
OriginZ     pixels

Because this operator supports the  PowerPlugs! -concept further
settings can be adjusted from within the global  Render-Settings -Window.
