There are two ways to adjust them, the first one is manual adjustment, which is a knob for Lens Shift, and a ring for Zoom, the second one is automatic adjustment. Geometry adjustments for seamless edge blending(1-1) Optical Alignment, adjustment of the Lens Shift and Zoom of lens increases the precision and flexibility of projection locations.
Instead, to them, it appears to come from a single projector this is the most successful seamless edge blending.ġ. The projection is considered good when viewers are unaware of the fact that the projection is achieved through multiple projectors. Multi-projection is made possible through two or more projectors, to achieve a display larger in size and resolution.
GPUs also bring additional benefits to warp and blend: Since the pixel information is already available to the GPU, the GPU is the natural place to do this work. It can also be done using software applications but that may not conform to all use cases. Traditionally, warp and blend is integrated into the projector or done using custom hardware appliances which adds performance delay to the display pipeline. In other words, you need to make sure that the slices overlap the same way as your physical projectors do in the real physical world. This overlap should mimic the physical overlap of the projectors on your surface. In order for edge blending to take effect, you need to have your slices partially cover the same area of your composition.
