Rotate Controls

This option allows you to rotate your controls whilst lining up, This is especially useful when your projectors are rotated for example if they are portrait in orientation rather than landscape.

There are four options: 

  • None: Mouse and keyboard operate normally.

  • 90 degrees clockwise:  mouse and keyboard are rotated 90 degrees clockwise

  • 180 degrees: mouse and keyboard are rotated 180 degrees.

  • 180 degrees anti-clockwise: mouse and keyboard are rotated 180 degrees anti-clockwise.

Lineup output mode

Lineup output mode allows you to change what is applied to the output whilst lining up.

Please note: During QuickCal lineup all lined up reference points will be drawn on top of the selected output.

​ You can choose between the following output modes:

  • Content:  Outputs the content that's on the timeline.

  • Wireframe:  Outputs the wire frame of the model.

Reset options

To reset the projector so no points have been selected or calibrated either:

  • select reset reference point lineup (current pose) to reset the points for that pose in a multi-pose line up (see the Multi-pose calibration sub-chapter for more info on this topic)

  • select reset reference point lineup

    Reset reference point lineup.

  • A warning message will pop up when you select reset projector config,Click yes to reset projector config.


Confirm reset projection config.

Removing reference points

There are 3 options for removing reference points under the Reference points tab:

Deleting reference points.

Delete unused reference points

This option deletes reference points which have not been associated with a projector lineup.

Delete unparented reference points

This option deletes reference points which are not parented to a screen

Delete all reference points

This option deletes all reference points from the virtual stage.

A warning message will pop up when you select delete all reference points , Click yes to delete all reference points.


Confirm delete of all reference points.

Warning: Delete all reference points is a global action, It will affect all the reference points on the model not just the ones associated with the current projector.

Advanced options

Follow screen changes

This option allows you to choose if the reference points follow screen changes. For example if you change your screen position the reference points will move with the screen.

Warning: This will automatically update any projector's QuickCal calibration using the new 3D positions of the reference points

Notify screen changes

This options allows you to choose if you want to be notified of screen changes. For example if the screen position changes and the points move with the screen you will be notified. The notification will ask you whether you want to update the QuickCal calibration with the new 3D positions. It will also show by how much each reference point has moved.

No. of moved reference points

This informs you how many points have moved with a screen position change for example.

Auto z-clipping

If auto z-clipping doesn't work, this means some parts of a Screen, which are either very close or very distant, may only be partially visible. then manually adjusting these near/far values can make sure that the projector renders the whole screen.
