Motivation

Imagine to synthesize the video below in comparable visual fidelity within temporal interactive constraints. Possibly by using suitable data embedded in some high-dimensional space? Recall the challenge of these high-frequency distributions within the nonlinear material and transport space!

How can we achieve both effective and efficient synthesis, seen from a theoretical and artistic perspective?

When I see great images, it feels like I want to simulate them.

Snow and ice geomorphology of Antarctica. This video poses a nice example of both theoretical and computational problems related to a) surface representation and its reconstruction, b) complexity of geological formations, fluid dynamics and evolutionary adapted biosphere, e.g. vegetation, microorganisms, algae and others, c) nonlinear radiative transport space, d) context of observation, e) computational efficiency, and many others. Efficient image synthesis shall be perceived as a optimal or near-optimal synthesis of these contexts as one. And this is what I am working on. Video courtesy Kalle Ljung @ vimeo.

Experience

Gave me a lot of experiences with CUDA and low-level optimized OpenGL. Sometimes it was just work, but most of the time it felt like fun. Thanks for giving me this opportunity.
