Implementation

Code is poorly written, due to the time constraint.

Objects

• loaded directly from .obj files using custom parser ObjFileReader
  • a crude parser for personal use only
• complex objects are downloaded from free platforms and some I made in blender.

Textures

• loaded using stbi library
• some 2k to 8k planet textures dowloaded from multiple sources

Animation

• all data (e.g. axial tilt, inclination, orbital period etc.) regarding tranformation of bodies are gathered from wiki and can be found in Excel Sheet
• orbits are animated using custom circular or elipse shape orbit
• apart from scale, distance and orbit shape everything else regarding the angle and daylight cycle are accurate for all bodies.
  • e.g. earth spin roughly 365 per orbit, moon is tidally locked can be observed.
  • No physics implemented thus the animation will not be accurate.

Shader

• phong
• spot light phong
• additonal shader code for night light texture of earth facing away from sun

Dependencies

• OpenGL, GLFW are configured
• Visual Studio 2022
• Visual Studio 2019 Available in dedicated branch
