Revision 2025

  • Revision 2025 - Seminar - Lightning Talks - How PC Intros Are Made - A YouTube video about how PC intros are made. From the description: “Learn how modern intros are made, from 4k to 64k, with a series of lightning talks by Prost, Cédric, NuSan, NR4, Zavie, and Psycho. From procedural mesh generation, color manipulation, character animation, raytracing, and sync, they’ll share the techniques used to create stunning prods. Whether you’re a seasoned demoscener or simply curious how the magic happens, this is a fast-paced, technical deep-dive into the art of PC intros.”
  • Slides from the talk - A Google Drive document with the slides for all talks

These two links have lots of techniques and ideas to use for 1k - 64k intros:

  • https://in4k.github.io - Resources mentioned in the video. “The goal of the in4k site is to be the central resource about creation of demoscene 1kb, 4kb and 8kb intros.”
  • https://64k-scene.github.io - The digital art creations below are “64k intros”: small computer programs of 65,536 bytes or less, that present a short audio visual experience. They are a showcase of creativity and technical skills, using techniques like procedural generation, sound synthesis, and real-time graphics. More info.

NuSan mentioned an interesting technique in the first talk (Pathtracing an infinite amount of primitives (but fake)) called: “Analytical Raytracing” where you “Skip the raymarching loop toward the surface by just knowing immediately the contact point” and you simply “compute it analytically for primitives (spheres, boxes, cylinders, capsules”. The technique works ok when you have very few primitives. To make scenes look more complicated she describes a way to do “domain repetition” as it’s often done in raymarching.
