Learning to create an infinite grid procedurally using GLSL shaders. This post contains my notes, lessons and findings, and is intended for personal reference. Therefore, you might find errors, misjudgments, and other issues, which are fine by me because my intention was to learn by teaching myself. In a way, I was being my own rubber duck.
The Best Darn Grid Shader (Yet)
For as long as I’ve been writing shaders, there’s been one specific shader I’ve always tried to write…

Evaluating and Sampling Glinty NDFs in Constant Time
Geometric features between the micro and macro scales produce an expressive family of visual effects grouped under the term 'glints'. Efficiently rendering these effects amounts to finding the highlights caused by the geometry under each pixel. To allow for fast rendering, we represent our faceted geometry as a 4D point process on an implicit multiscale grid, designed to efficiently find the facets most likely to cause a highlight. The facets' normals are generated to match a given micro-facet normal distribution such as Trowbridge-Reitz (GGX) or Beckmann, to which our model converges under increasing surface area. Our method is simple to implement, memory-and-precomputation-free, allows for importance sampling and covers a wide range of different appearances such as anisotropic as well as individually colored particles. We provide a base implementation as a standalone fragment shader.
