This is a demo that simulates the common retro console effect of creating a horizontal offset for each scanline on the screen in order to make different wave effects. To make it works efficiently, it uses a geometry shader that takes in two points at a time and makes 16 one-pixel-high strips that are then offset from a table uniform that contains a value to shift for each Y-position on the screen. It contains the entirety of [https://github.com/devkitPro/citro2d citro2d], hackily edited to work with this. it was done just for convenience - you could certainly make it play nicely with citro2d without having to edit it. ==User guide== You can change some parameters for different effects. ==Controls== Up/Down - Change the time step Left/Right - Change amplitude L/R - Change scanline speed A - Sysle through the pattern function ==Screenshots== https://dlhb.gamebrew.org/3dshomebrews/scanlineoffsetshader3.gif ==External links== * GitHub - https://www.reddit.com/r/3dshacks/comments/u6rneo/scanline_offset_shader_demo_download_in_comments * Reddit - https://github.com/TheGag96/3ds-scanline-offset-shader
