In this part of the course, we give a tutorial on how to compose live visuals. First, we talk about hardware and software setup needed for a live visual performance. Then we present concepts to prepare and organize huge media libraries allowing for instant access during performance. Afterwards, we give an overview of the basic content elements and how they can be edited, timed or animated according to musical properties (provided by real-time audio analysis). Finally we explain the workflow during a live visuals performance and show how graphic designs can be successfully embedded in a real-world environments. During the talk, we will make several live demonstrations by using the Soundium system as case in point - but most concepts can be applied to other performance tools as well.

Feature point detection is generally the first step in model-based approaches to sketch recognition. Feature point detection in free-hand strokes is a hard problem because the input has noise from digitization, from natural hand tremor, and from lack of perfect motor control during drawing. Existing feature point detection methods for free-hand strokes require hand-tuned thresholds for filtering out the false positives. In this paper, we present a threshold-free feature point detection method using ideas from the scale-space theory.

Porting Game Engines to Direct3D 10: Direct3D 10 is a major revision of the Direct3D API, and poses unique challenges to games supporting multiple platforms while still taking advantage of the new capabilities. This presentation covers practical experiences in updating game engine technology to support and exploit direct3D 10, and the implications for hosting both Direct3D 9 and Direct3D 10 within the same executable.

While we have treated image texture synthesis until now, several dynamic phenomena can also be treated as texture. Ocean waves, waterfall, smoke from a chimney, fire burning in a fireplace, grass fields waving in the wind, etc. are all examples of dynamic textures. These dynamic phenomena exhibit locality and stationarity properties similar to those exhibited by static textures. Additionally, they also evolve in their appearance over time, governed by underlying physical processes such as motion, diffusion, turbulence, and other micro-scale phenomena.
