This is the nucleus of this game. A Microsoft Excel spreadsheet I’ve been working on the last three years. It calculates from the values in the orange fields in the upper left a complete Star System with 10 Planets and all of their properties using real physical formulas and some predefined tables. The data is not quite realistic, but realistic enough to create a believable star system on the fly. Based on this spreadsheet, I created the more advanced Star System Generator Demo and this will be the core of the game.
This demo shows simple interplanetary ship travel between two moving celestial bodies in 3D, initially inspired by the old game “Millennium 2.2”. I am using the exact body names from there (perhaps coding a remake some day) and real object radii / periods / sizes from Wikipedia (planets only, the moons would look weird and the scale wouldn’t fit anymore without major modifications).Read More
A simple 3D demo of gravitation in minib3d. Two bodies with different masses affect each other using Newton’s law of universal gravitation formula which is F=G*((M1*M2)/r²). Includes a single surface path visualization using quads to see the objects gravitation influence. In this demo I’ve used the mass of our sun for the star and the mass of our planet. You can interact with some keys, use the mouse to rotate and zoom the scene.Read More
This is an updated version of an older commandline tool to create pseudorealistic Star Systems. This version can visualize the data and you can fly around in the Star system. The colors represent the Temperature zones of the System. Red is very hot close to the Star, Green is the Habitable zone where liquid Water is possible while Blue is too cold and frozen. The white lines represent the Orbits of the Planets. The blinking green line shows the optimum distance of a habitable planet, but their distance could vary from that as other factors than distance are important to decide if a planet is habitable or has a good ESI (Earth Similarity Index).Read More
The Earth Similarity Index (ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from 0.0 to 1.0, with Earth having a value of 1.0; this is meant to simplify planet comparisons from large databases. It has no quantitative meaning for habitability. The ESI incorporates a planet’s radius, density, escape velocity, and surface temperature into the index.
