The rotation pivot section allows moving the rotation pivot to positions others than the layer’s center point. Any X, Y and Z Rotation applied to this layer then will use the new position as pivot. Please remember that Players do not support the Z axis.

Each position parameter covers the value range from -999.999 to +999.999 units (the DMX Control uses a 16 bit channel covering the value range -256 to +256 units, see below).

The Pandoras Box output is always 16 units wide. The height is calculated by the aspect ratio.
A 4:3 display is 16 units wide and 12 units high.
A 16:9 display is 16 units wide and 9 units high.

How the Rotation Pivot effects the rotation

Applying a Z Rotation with the default position of the rotation pivot (X/Y/Z Pos=0) turns the layer around its center point.

The image sequence shows Z rotation angles from 0° to -180°. The Rotation Pivot’s position is set to default (X/Y/Z Pos = 0; Center Point).

Now the position of the rotation pivot is changed to X Pos=8 (right screen border) and Y Pos=4.5 (top screen border).

The image sequence shows Z rotation angles from +90° to -90°, the rotation pivot is located in the corner top right.

Viewing the Rotation Pivot

In order to see the position of the rotation pivot in the Preview window, please do this:
1. Check the option “Show Handles” below the Preview window.
2. Now click the rotation icon on the top left.
3. The rotation pivot gets visible.

When changing the position of the rotation pivot with the rotation pivot X/Y/Z Pos parameters, the pivot will move to its new position. If the rotation pivot is located outside the output area, you may change over to Global Cam View to still see its position:

Image above: the position of the rotation pivot is changed to X Pos=-17.2, Y Pos=-7.1, it is outside the outputs visible area.
