This is one of my first 3D modeling projects in Blender and my biggest 3D modeling project so far. Continue reading
I 3D printed a model of the street where I live. This post will explain how I prepared the data for it.
This year I participated in my first game jam, the Global Game Jam 2018. With a team of artists, programmers and a sound designer, we made a video game within 48 hours. Continue reading
This is my graduation project I did in computer science. The goal was to come up with a method to generate 3D meshes of building roofs from point cloud data. The point cloud data was taken with aerial LIDAR scanners and is available online. In addition, I used building layout polygons, which are also available as open data. I tested several strategies to generate a mesh and I’ll explain the best one in this post. Continue reading
I wrote two programs that run on my LED matrix. They have different approaches and different aims. This post describes the one of them. Continue reading
I built an LED matrix out of 256 WS2812 LEDs. This post will describe which materials I used and which I tried with no success so you don’t have to. Continue reading
This spring, I spent some time at SAP’s commercial hackerspace. I wanted to explore how computer vision can be used with embedded devices and robotics. I built a demo that can detect QR codes and similar symbols and point a laser at them. Possible applications of this are putting QR codes on objects to help the robot locate them and grab or manipulate objects. Another possible use case is local navigation. A robot could infer its own location and orientation in space by detecting QR codes with known locations.
This is a game prototype I’m currently working on. The game is played online, on a real world map and the location of the player is also the location ingame, just like in Ingress.
I know that making an online game like this is an ambitious goal and it will probably never be finished, but this prototype is a good way for me to test the game mechanic and see what works and what doesn’t.
The prototype is a web app and doesn’t yet use the player’s location, meaning they can interact anywhere on the map. If all works out, I’ll make a mobile client, which will be the actual game.
The game is about finding resources and mining them. I’m trying to make the resource locations meaningful and related to the real world. So I wrote an engine that procedurally distributes resources on the map, based on map data provided by Open Street Map. This allows me to define rules like “Resource 1 can be found at water fountains near public parks”, or “Resource 2 can be found only in forests and only within 100 meters of a school” and so on. Here is an example:
This is a 16×16 RGB LED matrix, made of 256 WS2812B LEDs. It’s powered by a Raspberry Pi and can display images and animations. With a game controller attached, it can play games. Continue reading
