The Canvas tab displays a planar layout of the screens generated in the projection scene. The screenshots below illustrate examples of canvas layout for a box an immersive room and a cylinder projection scene respectively.

The topology of the canvas should mirror the topology of the multiple monitor setup in Windowscan be adjusted to suit the installation. For a projection scene with no floor projection this , the topology would typically be a horizontal row of monitors. of screens. However, if the horizontal resolution is greater than 16k pixels, then moving some of the screens to form a grid instead of a row will allow the canvas to fit within the 16k x 16k limit.
For a projection scene with floor projection, it is common to have a grid arrangement, with the floor ‘monitors’screens, positioned below the monitors screens used for the walls. In this case, the The advantage of this approach is that the width of the walls corresponds to the width of the canvas, and this has benefits when moving and scaling content. Also content can be moved from the walls to the floor with an intuitive ‘downward’ action. The illustration below shows how the floor screens can be repositioned using the left mouse button to drag them to a new location, as shown below.

Canvas Resolution
The Canvas Resolution (px) valuesgive the overall canvas resolution in pixels specified in width and height respectively. The canvas resolution is calculated using the resolution of one of the width and height parameters together with the aspect ratio of the screen. Enter the known value of one of the parameters, based on the immersive space design drawings. The other dimension will then be automatically calculated and updated.

The Projectors tab presents settings which control the appearance of the test image . It also and defines how many projectors are used in the immersive space, which in turn, provides settings for a multi-window setup of ICE.
...
Grid Spaces, Grid Thicknessand Font scale are parameters affecting the appearance of the test image. A test image preview is displayed to help visualise the effects of changes.
For Cylinder projection scenes with floor projection, Guide Lines, with a Guide Thickness parameter, can also be added to the test image to help with the warping alignment.
