Here’s a shot of a desert crack CSG brush. The brushes are modeled by artists as if we’re performing CSG on a flat ground, instead of a spherical surface of a planet.

Jonathan Mavor, CTO of Uber Entertainment, wrote a blog post that elaborates much more on this specific topic. subtractive brushes are used to create cracks and pits into the ground. In Planetary Annihilation, base brushes form the base geometry of a planet additive brushes are used to form hills, mountains, plateaus, ice cliffs, etc. Below is a simplified 2D diagram explaining the process:īase brushes are the base geometry we start with, and additive brushes are “union-ed” together with the base brush, where subtractive brushes “eat away” regions from the base brush. This is probably best explained visually. Basically, CSG involves combining multiple solid geometry, called brushes, to construct more complex geometry. The planet geometry is generated through a technique called Constructive Solid Geometry (CSG), also known as 3D Boolean Operations by 3D modelers. My latest work that is worth mentioning is the bending of solid geometry. Recently I’ve moved on to polishing the procedural planet generation. Here’s the alpha release trailer that shows off Planetary Annihilation’s unprecedented epicness.įor the first 6 weeks of the internship, I spent most of my time on the in-game planetary camera and celestial camera.

Planetary Annihilation is a next-gen real-time strategy game on a planetary scale, where players fight across multiple planets. Many people on the development team have worked on Total Annihilation and Supreme Commander, and you can see the similarities Planetary Annihilation share with these two games. Two months ago, I started my internship at Uber Entertainment to work on Planetary Annihilation, which is currently in closed Alpha (you can still purchase Early Alpha Access into the game through Uber Store or Steam).
