Crescer3D – An adaption of agar.io

In the summer term 2016 a group of students, including myself, created a 3D adaption
of the classic web browser game agar.io. The game was created as part of the course“Computer Graphics“ at Linköping University, Sweden. The game is a combination of
fun ideas, an use case to learn game development and the CG rendering pipeline.

The code is hosted on github: Crescer3D

Starshooter – a web based wheelchair trainer

As second project of my time at the KTH Stockholm we developed
a game that is built to enable people that recently started to use
a wheelchair to learn how to „pitch“, which refers to the vertical
lifting of the little front wheels that is necessary in a lot of everyday
life situations.

The game is hosted at: http://starshooter.kspri.se

The „about“ section of the games homepage gives further information.

Padawan 101 – VR based Lightsaber Simulator

In the winter term 2015/2016 I was guest student of the computer science and communication department at KTH Stockholm. The most interesting project I was participated is a group work
of 5 computer science and media technology students. We were developing a game where people are encouraged to blend into the role of a young yedi aspirant, trying to learn the fight with lightsabers. The first prototype consisted of the Oculus Rift Headset and the Leap Motion controller and was presented to a public audience.
Eventually we were working on improving the game and presented it at Comic Con Gamex in Stockholm in October 2015. Here you can find a Facebook event for the presentation.
My work in the project:

  • First:
    • developing a finite state machine software structure
      to couple the different game elements.
    • integrate the leap motion sensor information
      correctly with our virtual lightsaber.
  • Second:
    • working on using gyro/accelerometer from a smartphone
      to get rotational information out of a smartphone and
      the Kinect SDK for positional tracking.
    • implementing a sensor fusion algorithm that smoothly
      integrates the positional information from Kinect,
      the rotation data from gyro and accelerometer
      into a smooth 6DOF tracking.

Stockholm Street Art

Stockholm Street Art – 13.09.2015

Compared to other big cities street art is very rarely seen.
This is possibly also due the high fees if you get caught.
At one area in the south of Stockholm, artists are allowed
to work on several walls of private property.

Skansen Open Air Museum

Skansen Open Air Museum – 23.08.2015

Skansen is an open air museum that showcases swedish daily life in the countrside up to 100 years ago. You can visit old buildings that are originally from that time, being moved to Skansen
at some point to keep this view into history.

Stockholm in the summer

Stockholm in the summer – 10.08.2015

This post is intended to give you some impressions from Stockholm in the summer.
As i moved to the city and had some weeks off before my classes at university started
i had the opportunity to dive into the city and take some pictures from its beauty.

Stockholm is beautiful in the summer.

Everything is close to the water.  A big lake to the west and the baltic sea to the east.

Independently where you are in Stockholm it is only a short trip to its surrounding nature.

Also good looking when the sun is leaving.

The vasa museum shows a warship from the 16th century that sank on its maiden voyage.

In the summer people try to make most out of the sun they can, here at a skate contest.

Stockholm is also famous for its well designed subway stations, here „Kungsträdgården“.

Computer Vision supported Robot Card Game

A university project as part of my master studies was to develop
a application for the NAO Robot, enabling him with computer vision
technology to play the card game Blackjack against a human person.
The robot was detecting the game card on the table and recognize
the correct card values through a feature detection algorithm.
He expressed his decisions with speech and gestures.
The project was done in about three month by three people in summary.

Written in Python by using OpenCV and Numpy.

Guest Lecturer at SAE Institute Stuttgart

I am happy that I am able to get my first experience as lecturer this summer.
I will give two courses about advanced game programming techniques at the
SAE Institute Stuttgart.

In the first course i will work with my students on recent releases
of the game industry like Virtual Reality Glasses e.g. the Oculus Rift
or alternative input methods like gesture control etc.

In the second course we will examine the needs for a basic game
engine together and write a simplified version live in the class.

Looking forward to it!
