AdVis has a built in edge-blending algorithm so you can create seamless displays out of multiple projectors.
After configuring multiple cameras to run multiple displays, you can enter the 'Edge-Blending Configuration' to tweak settings such as edge-overlap and colour settings.
You will be show a full screen display similar to above. This is the default view for two projectors side by side with edge-blending enabled.
For edge blending to work, your projectors need to overlap each other at the edges. A 5% overlap is normally enough to get good results.
Press 'Space' to enable or disable edge blending.
With edge blending enabled, you need to adjust the overlap until the two projected images look like one seamless image. For two projectors, you can use the 'Q' and 'A' key to adjust this overlap.
Unless you notice colour problems where the projectors overlap, you do not need to adjust the other settings. If there are colour problems, you can experiment with adjust the different colours and gradients. Press 'X' to reset the settings back to default.
If the image across the two projectors looks like the image below, then edge blending is correctly configured. Press 'Enter' to save these changes. Press 'Escape' to exit the edge-blending configuration.
