Wings Vioso offers a number of masking functions for various calibration problems:
Mask for the camera image during calibration ...prevents bright light sources, e.g. lamps, windows or reflections from influencing the calibration. This mask is a fixed component of the calibration process. See Camera-based calibration.
Masks for the projectors during calibration ...have a similar function as the above. In order to open the Mask Editor after the brightness measurement click Advanced under Further options and select Mask projectors.
Masks for the content ...allows masking of the content to be played. During mapping these masks are shaped together with the content. The Mask Editor can be opened via the Calibration Properties by clicking button Color & Blending and selecting Edit... under Mask output.
Masks for individual projectors ...allow the projected images from a projector to be masked. This is useful if a projector projects onto some struts or off the actual projection screen. The Editor for these masks can be opened via the Calibration Properties by clicking button Projector... slicken. In the dialog popping up select the corresponding projector and click on Edit... In order to identify individual projectors in an overall projection you can activate Identify displays.
