Farbraush Demo Tools

Farbrausch released the source code to all their demo tools, including kkrunchy, ktg and werkkzeug3. And following the move, Moppi Productions released the Demopaja source code. A good day for demoscene coders.

For more info on these tools take a look at the Demopaja documentation and werkkzeug3 documentation. (FYI, werkkzeug is a german/elite-speak word for "tool", or literally a work-thing). Dirk Jagdmann has a nice online presentation on the Farbraush/Elitegroup demotool approach, and Dierk 'Chaos' Ohlerich has a number of good presentations:

• A history of Farbrausch tools at Assembly 2003. (avi download)
  
• A workshop of .werkkzeug1 at Assembly 2004. (avi download)
  
• From .kkrieger to debris. Procedural Content Generation Taken to Extremes NVScene 2008.
  
• and .kkrieger - Content creation in 96kb presented by Thomas Mahlke and Christoph Muetze at Assembly 2004.
  

Over the years I've collected a number of great snippets of tips'n'tricks from various bits of FR code that have been opened (e.g. this gem by Dierk 'Chaos' Ohlerich on FPU intrinsics), now you can get it all in one big collection. As the FR release is just a big dump of all the material, here are a few relevant posts to help you decipher what is going on:

• kkrunchy - A 64K executable compressor, see Fabian 'ryg' Giesen's presentations on compression, and more info on his blog post on how kkrunchy works. For more general background, I did a post a while ago on executable compression and various compression algorithms.
  
• V2 - A software synthesizer by Tammo "kb" Hinrichs, who used to have some great articles on his site describing how V2 worked. There are backups of his articles 'The Workings of fr-08's Sound System' here: Part 1: The Concept,Part 2: Why are SMF Files Smaller?, Part 3: The Basic System and Part 4: Let's Talk About Synthesizers. Related, is this article on 4klang a 4k synthesizer and an article I wrote on the basics of sound/instrument generation including wave generation (sin, square, etc.), ADSR envelopes, and modulation/filtering.
  
• ktg - Texture generator, not aware of much content on this from FR themselves, but thats probably because there are excellent articles on this by Ile / Aardbei 'Generating textures for 64k intros' (ATG is still my favourite texture generator), and the more in-depth 'Texture Generation For 64k Intros' by Nicholas Nash (Paradox / Vivid).
  
• genthree - Code for Candytron, with the beginnings of the half-edge mesh generator (see '20021211: neue meshes' in diary.txt) that is described in some recent blog posts by Fabian 'ryg' Giesen in Half edge theory and practice.
  
• lekktor - FR's failed dead-code removal tool, described in this blog post by Fabian 'ryg' Giesen.
  

I'll leave you with some of Farbrausch and Moopi's favourite productions to inspire you to decipher the code:
