#Propresenter edge blending software#
Modify the software application to have the same calculated overlap regionīelow we show an image before and after overlap regions are implemented. Once the projectors are aligned, overlapped and ready to go, the software then has to be adjusted to provide the same overlapping regions.

Here for illustrative purposes, we show an example of projector placement on a curved screen with the overlapping regions described above. The exact layout of the projectors will change depending upon screen size, screen shape and the optics of specific projectors used. Once the overlapping regions have been calculated, we can then align the projectors and software.Īlign the projectors to produce the calculated overlap Figure 2: Projector layout with overlapping regions. As we have two overlapping regions between our three projectors (as shown in Figure 1), our overall displayed resolution will be: Taking our 12.5% overlap region, this equates to 160 pixels with our SXGA projectors (1280 x 0.125 = 160 pixels). In the example described, the total available resolution of the three projectors titled horizontally before overlapping is: In this example we use a 12.5% region because existing resolutions result in whole pixels: However, because of different projector resolutions, it is good to standardize on the same overlapping region. Note: It is good to have a complete number of pixels and the same physical screen size when edge blending. Figure 1: Example overlapping regions of 3 SXGA displays. Each projector has a resolution of 1280×1024 (SXGA). Modify the software application to have the same calculated overlap region.Īs an example, here we present overlapping regions based upon a three projector setup.

Align the projectors to the calculated overlap.Three steps are required in order to produce an overlap region: In this overlapping area, edge blending is later applied. Before edge blending can occur, the projectors and software application need to be set-up so that an overlapping region between the edges of adjacent projectors is present.
