Squares, boxes, and rounded rectangles are all common shapes you might want to draw in a shader. In this video, I show you how to do that using 2D signed distance fields, or SDFs. We'll derive the formula, recreate it in the shader graph, and then make some cool shaders to see it in action: including a mouse-controlled rectangle drawer, rainbow SDF visualizer, and procedural brick wall.
