Comparative Analysis of Procedural Planet Generators

This paper presents the development of two distinct real-time procedural planet generators within the Godot engine: one employing Fractal Brownian Motion (FBM) with Perlin Noise, and another adapting Minecraft-inspired layered noise techniques. We detail their implementation, including a quadtree-based Level of Detail (LOD) system and solutions for planetary mesh generation. A comparative user study (N=15) was conducted where participants explored unique instances generated by our two algorithms alongside two existing procedural planet projects.

How Often Should People be Tested for Corona to Avoid a Shutdown?

Based on the well known SIR model, this paper develops a model for predicting the number of necessary testings of asymptomatic persons in order to push Reff below 1, thus suppressing an outbreak. The model considers R0, time for obtaining a test result, and effect of population discipline. The outcome are closed form expressions for the number of daily tests.
