The document discusses the origins and characteristics of the demoscene, highlighting its basis in extreme programming and real-time procedural visualizations rather than pre-rendered animations. It recounts the challenges faced by early developers in a time without advanced computing resources and emphasizes the collaborative nature of demo creation, involving programmers, musicians, and artists. Additionally, it touches on the use of old-school tools and techniques while showcasing a specific demo titled 'Voodka' by Absence from 1996.
Demoscene Stories, and Old-School Code Tricks presented at FMX2015
- 1. DEMOSCENE STORIES, AND OLD SCHOOL CODE TRICKS Rafal Koffer Ice-k (Incuvo) & Tomasz Bednarz Warlock (QUT, ACM SIGGRAPH IRC )
- 2. DEMOSCENE demoscene was born in the computer underground, and demos are the product of extreme programming and self-expression
- 3. DEMOSCENE VS VFX Demoscene is all about all computations done in real-time Demoscene productions run as standalone executables (not pre-rendered animations) Demoscene executable has total size not over 4kb, 64kb, etc Demoscene needs to use many procedural generators to overcome size limitations (generate music, textures, meshes in fly) - rather than load and operate on big source files
- 4. OUR STORY
- 6. HOW WE HAVE STARTED Early computer exchange/market
- 7. COMPUTER MARKET AND VIRUS STORY
- 8. BEGINNINGS WERE CHALLENGING MATH KNOWLEDGE ON LEVEL OF ALU
- 9. NO FPU BUILD IN BEGINNINGS WERE CHALLENGING
- 11. NO INTERNET !!! BEGINNINGS WERE CHALLENGING SWAPPING ONLY!
- 12. & NO REFERENCES AVAILABLE, JUST EXPERIMENTS BEGINNINGS WERE CHALLENGING
- 13. BUT...
- 14. IN EUROPE EVERYBODY C++
- 16. WE HAD A DREAM TO CREATE IMPOSSIBLE
- 17. WE TRAVEL TO THE PARTY PLACE
