Abstract:
In a multichannel display system, a method for implementing edge blending between a first and second video frame to create a seamless multichannel display system, comprising:a) rendering a first video frame for display on a first channel; b) rendering a second video frame for display on a second channel; c) rendering a first overlap region onto the first video frame to obtain a first blended video frame; d) rendering a second overlap region onto the second video frame to obtain a second blended video frame, wherein the first overlap region and the second overlap region are implemented by producing a first polygon to define the first overlap region and a second polygon to define the second overlap region, and mapping a first texture over the first polygon and a second texture over the second polygon such that the first and second textures modulate a brightness level within the first and second overlap regions; and e) combining the first blended video frame from the first channel and the second blended video frame from the second channel such that the first overlap region and the second overlap region correspond, thereby forming a seamless junction between the first blended video frame and the second blended video frame.
