Seemless real time portals using stencil testing When I first saw the portal mechanics in Valve's Portal game, I was immediately fascinated by them. Each portal does not only show in real time what lies behind it, but also allows seemless traversal. I always wondered how exactly Valve accomplished that, until...

Voxel terrain generation with Perlin noise and instanced rendering The goal of this project was to achieve a Minecraft like terrain generation. I was especially curious about any performance pitfalls that might arise. I used my own engine, because I wanted to test and possibly extend its capabilities. The first thing I...

Minimal game engine written in C++ using OpenGL In this post I would like to showcase a game engine based on the OpenGL API, developed in C++. It is still in an early stage and only covers the bare minimum that is necessary to qualify as a game engine. Nontheless, it...

A genetic algorithm using neural networks in Unity Genectic algorithms are used to solve optimization/search problems, by mimicking biological processes like natural selection and mutation. They pair very well with neural networks, which for me, is a facinating combination. This is why I decided to learn more about it by implementing...
