We set two new vectors, dimension and offset, in which well store the dimension and position of our DOM image. Shaders that draw an image or texture directly. I downloaded the source files, but it seems the project doesnt run. representative color. With low precision sRGB buffers, colors will be clamped to [0.0, 1.0] and information loss will shift to the darker spectrum which leads to noticable banding in dark scenes. This has the big advantage that we don't have to wait for the texture to load and our Until we want them to stop being sticky and move normally. This isnt perfect and I might have missed some details but I hope youve enjoyed this tutorial anyway. Move your mouse right and left, top and bottom to change speed and direction.
