As an exercise for the university I had to calculate music artist similarities based on co-occurrences in user generated playlists. Such similarity measures play a vital role in many application scenarios of Music Information Retrieval (MIR), e.g., in music recommendation and playlist generation applications.
Skinning with VVVV’s character animation nodes
After having explained how to create skeletons for 3D characters and animating them in VVVV, this quasi-article shows how to use VVVV’s character animation nodes in combination with software and hardware skinning methods.
Character animation in VVVV
As my weapon of choice, the visual programming environment VVVV provides a huge amount of functionality in the area of multimedia and 3D computer graphics - all accessible in a nice non-textual programming environment. While there exist several ways of manipulation 3D geometry in VVVV, right now there are no explicit methods for doing character animation.
So, this project (which was topic of my diploma thesis) aims to create an API, which introduces the terms of character animation to the world of VVVV. In this article I’m giving a little introduction of the developed nodes, and how to use them.
In search of a suitable object model for describing charts
When looking at various charting libraries I usually see the developers using concepts like Series, Categories, Axis, etc.
For some reason I’ve always had troubles wrapping my head around those concepts in order to ‘think’ in those terms.
Quadratic bezier curves for Processing.js
Since Processing and respectively Processing.js don’t support quadratic curves, you are forced to construct them with a conventional cubic bezier curve. I’ve never used bezier curves before, so I took this as a lesson.
Etage 12900
Last April I played a VJ-set at the closing event of vienna’s sound:frame festival at the Fluc Wanne. Now i finally managed to patch up some documentation about the content I built especially for this event.
Motion Tweening for Processing.js
Creating animations in Processing.js can be a quite hard and repetitive job. Having a simple library for animating graphical objects probably makes the ambitious animator’s life easier.
18Bit Webshop launches
Our dear friend, the 18Bit shop, expands its business from Linz to the rest of the world, by launching the 18Bit Webeshop www.18bit.com, created here in the Quasioffice.
jQuery UI Multiselect
Whenever you are dealing with Select Multiple inputs, be assured it hurts. Using Javascript you can spice up that unhandy plain old vanilla Select Multiple element that comes with your browser. Inspired by various existing solutions I ended up in creating my own version of a sortable, searchable Multiselect Widget.
A call from the past
Half a year ago we had our grand office launch party, the Quasipartikeller. Unfortunately, documentary material is absolutly rare. Most of the photos taken are from the morning after — and believe us: nobody will ever see those pics. But now some explosive evidence appeared.
