BubbleView

I've been experimenting with a data set visualization concept that acts like a visualisation of a bubble-sort. At the moment my plans and ideas for this thing far exceed the fragile proof of concept prototype I've got.

The simulation engine still needs a lot of performance and stability improvements, and then more interesting possibilities can be explored.

Based on my early experiments with this concepts it seems like it can evolve into useful interfaces for selecting items, exploring data sets with different sorting constraints applied. Interaction methods directed at making CBIR exploration of databases efficient as well as a combined filemanager/media viewer.

Spring has arrived

The ice on Mjøsa has melted and spring is rapidly proceeding.

I'm starting to think that I should create a new and better gallery for my images, my recent adventures in the land of web 2.0 has left me with some ideas for how to create a minimalistic system that has only static content on the server which is processed on the client for slideshows, tag based searching and more.

DHTML Pong

Press image below to launch a — XHTML+CSS+js standards compliant, cross browser supported without hacks — implementation of clasiscal digital gamer tennis. Avoid moving your mouse at all after loading to have two "ai's" competing each other.

I've been brushing up my js-fu the last couple of weeks due to extra responsiblities at work that have distracted me from hacking on the usual projects. This has led to a pong game and a popup-index and tagcloud for the static content web 2.0 blog renderer at codecave.org.

Robotic Aquarell Vision

When experimenting with an approach to tonemapping I've stumbled across a nice artistic aquarell like rendering filter. This rabbit looks nice with a more basic variation

The State of GEGL

The presentation I did at FOSDEM this year is now available online. In multiple forms, a video (300mb OGG/Theora), a large image and a tarball containing the GEGL compatible XML file with included media assets and a ruby program for viewing it.

FOSDEM was a nice experience, the amount of participants increases every year and it is great fun to meet up with people I haven't talked to for a couple of years as well as met a bunch of new people doing amazing things using our free tools and infrastructure.

FOSDEM Interview

I have the pleasure to present at FOSDEM this year. Part of doing a main-track presentation at FOSDEM is the speaker interview, the good people of FOSDEM performed it by email. Doing it by email gave me ample time to consider what I wanted to say, as well as getting help from other people involved with GEGL to correct my worst abuses of the english language. Read the interview.

Ruby meets GEGL

GEGL is written in C, but I think and hope that interesting applications will surface written in higher level languages. I am having fun combining GEGL Ruby, GTK+ and cairo in a test application that focuses entirely on manipulating objects in a zoomable canvas on the canvas that uses pie menus. The test application and the rest of the code for the user interface resides in the nicely forming rgegl extension for Ruby.

It is nice to code in Ruby again, it seems like I can get much more done in one hour with ruby than a whole evening with C.

Public GEGL API Reference

Work is under way on documenting the GEGL API. The core of the API is rather small (less than 15 entry points for the core of creating and processing image compositions, and the rest is syntactic sugar or state queries).

Please also look through this API with a critical eye and report thoughts on the API back to the GEGL mailing-list. Improvements to the text itself are best sent as a patch against gegl.h in subversion.

The document is transformed from .h into .html by a ~500 line HTML/CSS/ruby/regexp contraption.

The rest of the web on gegl.org is still the one from the previous release, when the next release is done the API Reference will also be linked from the front page.
