Four short links: 3 Sep 2010

Design Principles, Mario AI, Open Source Wave, and 3D Google Earth Sound

  1. Arranging Things: The Rhetoric of Object Placement (Amazon) — […] the underlying principles that govern how Western designers arrange things in three-dimensional compositions. Inspired by Greek and Roman notions of rhetoric […] Koren elucidates the elements of arranging rhetoric that all designers instinctively use in everything from floral compositions to interior decorating. (via Elaine Wherry)
  2. 2010 Mario AI Championship — three tracks: Gameplay, Learning, and Level Generation. Found via Ben Weber’s account of his Level Generation entry. My submission utilizes a multi-pass approach to level generation in which the system iterates through the level several times, placing different types of objects during each pass. During each pass through the level, a subset of each object type has a specific probability of being added to the level. The result is a computationally efficient approach to generating a large space of randomized levels.
  3. Wave in a Box — Google to flesh out existing open source Wave client and server into full “Wave in a Box” app status.
  4. 3D Sound in Google Earth (YouTube) — wow. (via Planet In Action)
