Exotic Matters Engine

Squishy People and Hard Science

A program for course plotting and mission simulation for the Tabletop RPG Exotic Matters: A scientific, mathematic TTRPG by Alexander Lowry

This TTRPG comes with a program to plot and calculate trajectories, plus a book containing the rules for play.

Both are incomplete right now! Neither are completely workable yet.

Building the program

Assuming you have cargo and Rust (>=1.89.0) installed: cargo run --bin exotic_matters --release. First-time compilation will take several minutes: about 15 minutes on my M3 Mac, and 30 minutes on my Ryzen 7.

To Do List

• Shader to see light shine off distant objects
  • Sometimes objects are smaller than a pixel, so their bloom disappears suddenly or flickers
  • Screenspace shader that gets coordinates of objects and angles to light sources
    • phase angle?
• Add textures to objects
• Rotation and quaternion stuff (sadge)
• Procedural textures for planets
• Procedural textures for ring worlds
• Dyson spheres
• ring wolds
• potato asteroids
• rosettes
• klemperer rosettes
• let things change course over time (impulses)
• SOI changes
• Make ring habs scale properly with distance/object scale for symbolic views
• Bouncy animations for changing size
• Automatic size presets for useful stuff
• Information about trajectory lines on hover
• Little spacecraft type of object
