The collision detection will facilitate the creation of more complex scenes with more objects on the planet's ground or in the air. On the 6th of January I'll start working on the physics part of my engine. From today until the 23rd of December I'll be simplifying the content creation process and I'll be also optimizing my renderer. In parallel, I plan to recapitulate my books about mathematics and physics. Over Christmas and New Year I want to improve my homepage and play lots of games.
