A 3D-Animation of H.R. Giger - Birth Machine

In "3D-Animation", a subject about creating and animating 3D-Scenes with Autdesk Maya, the main project was to create a scene of a popular painting and animate a flight through it. Background My teammate and I decided to go for H.R. Gigers Birth Machine since we both like the surreal arts created by Giger. The Birth […]

A Blog and Portfolio with SilverStripe CMS

A WebGL-based *.obj-Viewer with three.js

As WebGL gets bigger and bigger, I tested some technologies and libraries for creating WebGL-Applications. While testing I created an *.obj-Viewer.*.obj-Files store information about a 3D-Object, for example the faces and normals of an object. The tool was created with three.js. You can find the tool with some example files here!

Fish-Tracking with OpenCV

The "Alfred Wegener Institut für Polar- und Meeresforschung" currently does research on the behaviour of sea robins.

The Fish-Tracker simplifies the data collection alot. The […]

JumpiN - A Doodle Jump Clone with Google PlayN

Google PlayN offers the possibility to write games for multiple platforms from one single codebase. A game is written in Java and can be compiled to Android, HTML5, iOS and Flash. This makes cross-platform-development very easy. As a first project I choose to create a Doodle-Jump-like game. Next to PlayN I use a library called […]

Rollercoaster with Python and OpenGL

While learning OpenGL and the mathematics behind it, I implemented a rollercoaster with Python and OpenGL. The track can be loaded from a *.dat-file. If no file is loaded the track is created randomly.

Web-based billing software with Zend Framework

The goal of this project was to get a web-based billing software for a health insurance broker company. The billing tool offers multiple areas with different UIs, one for each role. As the different roles have permission to manipulate data, it was important to secure the programm against e.g. cross-site-scripting and sql-injection, but also against […]
