Es gibt mal wieder einen Grund, sich so richtig auf das KBS zu freuen -- denn am kommenden Dienstag den 10. Mai 2011 gibt es dort prominenten Besuch. Zwei Mitglieder von farbrausch erzählen von ihrem Umfeld und ihrem Handwerk.

Wer oder was ist farbrausch?

Spielerei mit Streifenbildern

2010-10-10 15:57:43

Heute gibt's mal wieder etwas völlig anderes. Ich möchte euch eine Idee zeigen, mit der ich vor einiger Zeit mal herumexperimentiert habe, die mit der Wahrnehmung von teilweise verdeckten Bildern zu tun hat. Die Idee stammt aus einem Video, das ich vor langer Zeit mal gesehen habe. Dort hat jemand diesen Effekt mit schwarzen Silhouetten erzeugt. An dieser Stelle bin ich mutig und versuche es direkt mit einem Farbbild, allerdings einem einfachen. Hier ist eine Spirale:

Eine rot-weiße Spirale

Voxel based Mandelbulb in POV-Ray


Voxel based Mandelbulb in POV-Ray

This is a POV-Ray rendering of a 1024x1024x1024 voxel computation of the standard 8th power mandelbulb, as seen at Skytopia.

Rendered in 640x480, 24 FPS, using a combination of ray tracing (using two light sources) and radiosity.

Aesthetically, this doesn't really surpass existing videos. The fractal structure is not immediately apparent due to the relatively low voxel resolution. For me, this was more of an "I must climb it because it is there" idea. ;)

To see a way better, truly breathtaking mandelbulb rendering, see the work of Iñigo Quílez. Also, check out how Cyril Crassin does this in real time (!) using CUDA.

AarophY - Trailer

AarophY - Trailer

This video was created by Janina Nemec, Christopher Schewe and me for the Interactive Visual Computing course at the Department of Computer Science, University of Hamburg. The visuals are entirely made with POV-Ray 3.6.

This is a trailer for a fictional adventure game called AarophY, conceived as a sequel to the game ZuuL, which was developed in a different university course by a team of which Janina, Christopher and me were members. ZuuL, a rudimentary "dungeon crawler" with top down perspective, is where many of the ideas in this trailer originated - for example the cheese and sausages that seem to be strewn around the chambers.

Shouts out go to Bastian Ruhrmann, who generously donated a custom piece of music originally created for a different project. The song that's played during the credits is called "I Feel Fantastic", sung and played by the fabulous Jonathan Coulton, and is used under CC-BY-NC.

We used a POV-Ray torch flame originally created by Kenneth W., for whom I unfortunately could not find a contact address (if you're reading this and want to be credited more/differently, let me know!), and a fur texture by Rune Skovbo Johansen, who has lots of cool and useful POV-Ray information, among other things, at his website:

Feel free to have a look at other movies created for IVC.
