Motivation

Mess around with OpenGL and Dear ImGui and make a cool rendering project

Showcase

Features

Configuration Menu

Ability to configure various properties of rendering, camera, and orbit

Light Effects

Ambient + Diffuse

Skybox

Milky way skybox so it feels spacy (actual word btw)

Uses Kepler's Equation to Calculate Orbital Position

Planets have different orbital parameters that are used to calculate their orbital position at a certain point in time

Easy Configuration:

Properties of different celestial bodies can be configured easily using the config.json file

"Earth": {
  "orbitParameters": {
  "semiMajorAxis": 1.000,
  "eccentricity": 0.0167,
  "inclination": 0.000,
  "longitudeOfAscendingNode": -11.260,
  "argumentOfPeriapsis": 114.207
  },
  "scale": 1.000,
  "texture": "./resources/textures/earth.jpg",
  "position": {
  "x": -1.000,
  "y": 0.0,
  "z": 0.0
  }
},
