A test pattern is overlaid for easier editing of the parameters when aligning the overlap for 2 projectors (both with respect to the overlap being located in the right place and also for adjusting the blend region to correct for gamma, since light doesn't really add up in a nice linear way). The image below shows edge blending editing in action, combined with projector distortion (this is all inside Racer no external tools are needed). More information on hooking up multiple computers to provide one image can be found at the multiview page. It described how the blend curve really works (it's not a linear degradation to black).Įdge blending requires multiple computers, rendering in concert. This all results in a slow mixīetween the two images, much less prone to be noticed by the viewer.Ī fabulous page on the internet about edge blending is located here. Transition from one projection to the other. Overlap becoming too bright, the edge is darkened towards black to make a nice Slightly, which smooths out any misaligned images. Parts of the center render (for example, not edge-blending dials/dashboards).Įdge blending works by having multiple projections overlap eachother Some tricks may be possible in the future to have edge blending affect only

However, it's not really required (it's easy enough to do it in software with Cg these days). More expensive projectors supportĮdge blending in hardware, as do some of the higher-end nVidia Quadro cards. free planning, project management and organizing software for all your action listsĮdge blending is only available to licensed users of Racer.Įdge blending is used when running Racer in a multiple projector
