As a reminder, please note that posting footage of a game in a standalone thread to request feedback or show off your work is against the rules of r/gamedev . That content would be more appropriate as a comment in the next Screenshot Saturday (or a more fitting weekly thread ), where you'll have the opportunity to share 2-way feedback with others. r/gamedev puts an emphasis on knowledge sharing. If you want to make a standalone post about your game, make sure it's informative and geared specifically towards other developers .

I wanted to clear up some misconceptions your post may cause. It's not a fragmental shader (nor is it "fragmetnal"). It's just a fragment shader. You wouldn't call a vertex shader "vertexal." My understanding is that the reason "fragment shader" is used sometimes instead of "pixel shader" (although they're interchangeable terms) is because the fragment color doesn't directly set the color of the screen pixel, since other operations like blend states, stencil testing, and depth buffer testing can cause the fragment shader output to be blended or discarded. It isn't called for "every texture pixel." That language inaccurately implies that if you're rendering a scaled up textured 3D polygon, the fragment shader is called once for every input pixel of the scaled up texture. It does not run once per red dot in this image: http://imgur.com/in1WbPK It is actually called once for every output pixel that the primitive being rendered covers. You also mention "In general even a drawing a textured triangle needs a shader." I feel the need to mention here that even an untextured triangle requires a shader. I thought "textured triangle" was a weird simplest example for you to give. More on reddit.com

EDIT: My new efforts have been moved into a different thread. Please comment there instead 🙂 I don’t know why, but I suddenly got it into my head that I wanted to make an NTSC/CRT effect in Unity. At first I tried to hack it. Every other “scanline” I offset texture by a pixel, and ... More on forum.unity.com
