Yeah, that's what I thought. I was trying to work out how to scroll a level on a 3D plane so I could use shaders, but the drawing of level segments confused me ish. I came up with a few methods one being creating a 1 pixel width frame around all the pixel in the middle, so the edge of the scene, and using a cell system around the edge to check if something needed to be drawn (only when moving), if it did, that row or column of pixels from a tileset would be pasted around the scene. I improved upon this by adding a offset modifier to the drawing frame, so if the scene offsets more than 1 pixels between frames it would extend the drawing width or height.
At this point I was thinking, sure there a better way of doing this and looked at example of shader with non-3d. One being using an offscreen render target to render a number of sprites, then applies a pixel shader to the full scene. Obviously you couldn't do this in DBP, so I just, has someone asked the question before and here we are.
A dream is a fantasy, if you achieve that fantasy it was never a dream to begin with.
