To work in the free mode, click “Switch to Free Mode”, if VIOSO 6 is not already started in this mode.

If you are using the free mode you need to configure your Setup in the Core itself. Displays Cameras and surfaces have to be inserted in the Core-View of VIOSO 6.
To enter the Process just click “Calibrate”.

The Core window will appear.

Choose the displays you want to be your outputs (projectors)–choose as many projectors as you want to calibrate on this setup. Once you have selected the projectors, by clicking on their name it will turn blue, marking the selected projectors.

In this section you will see any output connected to your PC or workstation and any screen you have connected to your system will appear on this list.

If you use a mosaic configuration, it must be divided again for the calibration so that each projector can be calibrated individually.

These are the typical topologies that desktop spanning can be set to:

Select method

Select the screen or surface type you are working with.

The following calibration modes represent different mathematical models for scanning and calibration. Thus, it is quite important to select the correct one.

Their names state the configuration they are dedicated for:

Flat screen (fast scanning)
Camera-based method for flat screens and slightly curved screens (Examples: projection screens, solid flat walls, ceiling, or floors).

Curved screen (fast scanning)
Camera-based method for any kind of curved screens, spherical screens, and domes (Examples: Planetariums, event domes, cylindrical panoramas, 360 panoramas, truncated domes, semi spheres, etc.). The method is also used to calibrate 3D structures. If you are not able to get a good result, try any surface.

Any surface (detailed scanning)
Camera-based method for any kind of uneven and complex surface. This requires a very clear image of the testing patterns filmed by the camera. Scanning will take a long time and is intended for experienced users (Examples: rock surfaces, uneven walls or buildings, textured and uneven surfaces).

Manual setup
The calibration will be done manually without the help of the camera.

Preceding calibration
Uses the parameters of a previous calibration.

Camera selection – Select the camera that you want to use for this calibration scan. If you don’t see the camera you would like to use, make sure your camera is connected.

Set a name for your calibration (optional).

Click ‘Next‘.
