Multi-projector output mapping
Circular generates one procedural texture and sends it to Window:/. The Window device is saved in Multi-window mode; its output regions, screen assignments and warps do the mapping. There is no intermediate mixer or rect-mapper process in this graph.
Try it
Open the Window device settings before playback and assign each output to a screen available on your machine. The saved desktop positions and screen indices describe the author’s setup, not your projector arrangement. Use the device’s test cards to align the source regions. Double-click a region to edit its perspective transform and the dashed border controls to adjust edge blending.
Start playback to compare the animated source across the configured outputs. Adjacent projectors need appropriately overlapping source regions and physically aligned images for useful blending. Additional outputs and larger render sizes increase GPU and display-system requirements; the example does not promise unlimited outputs.
No external image or video is required. Window output mapping is independent of Qt Quick 3D; it can also receive the composed texture from the rectangle-mapping example.
