I spent the past few months building my personal website from the ground up, finally taking the time to incorporate some 3D work to showcase my shader and WebGL skills. Throughout this work, I got to truly understand the crucial role that post-processing plays in making a scene actually look good, which brought some resolutions to long-term frustrations I had with my past React Three Fiber and shader projects where my vision wouldn’t materialize regardless of the amount of work and care I was putting into them.

Taking the time to build, combine, and experiment with custom post-processing effects gave me an additional creative outlet, and among the many types I got to iterate on, I always had a particular affection for the several “retro” effects I came up with. With subtle details such as dithering, color quantization, or pixelization/CRT RGB cells, they bring a pleasant contrast between the modern web landscape and a long-gone era of technology we 90s/early 2000s kids are sometime longing for.
