Procedural Textures: A Practical Introduction [Shaders Monthly #7]

Описание: In Episode #7 of Shaders Monthly, we talk about procedural textures. As a practical example, it is demonstrated how 2D shapes can be rendered with a GLSL shader using a signed distance function (SDF). Furthermore, we discuss how to perform distance-based anti-aliasing.

Here is the code of the created shader:
