Overview

With the rise of hardware raytracing new algorithms were created for games and other visualizations with a limited time to render the geometry onto the screen. Waiting hours for a single frame is not an option. Even while modern hardware raytracing helps to get the underlying intersection of the scene fast, a clever algorithm is key to balance interactivity and quality.

In this seminar you will implement, adapt, and evaluate a state-of-the-art algorithm presented in a recent paper. The implementation will be within the AnyDSL framework in the hybrid renderer Ignis, which is capable of rendering for hours like offline renderers or for some milliseconds as used in games on a GPU or CPU.

Modus operandi

  • Each participant works solely on his own topic …
  • … under individual supervision by an advisor of the CG chair
  • In the mid-term short presentation each participant gives a talk about the related work, his own research statement, and a roadmap until end-of-term
  • The end-term presentation showcases the implementation as a live demo embedded into a talk about the whole topic and the carried out research.
