Particle Accelerator

OwO what's this ?

This project simulates the behavior of a very simplified particle accelerator.
In the current configuration, it is a simple circular accelerator composed of straight elements, focalizer elements, and dipoles.
It is planned to add a way to edit the accelerator, but you can of course simply add it manually by modifying the code and recompiling.

Features

• Physics
  • Bi-directional accelerator for pawsitively and negatively charged particles
  • Inter-particle interactions
  • Käse (partition the accelerator in pizza slices to optimize inter-particle interactions)
  • Approximate and exact collision detection controlled by bool methodChapi (we however only use the approximate one here because we would have to recallibrate the accelerator's magnetic fields if we were to use the exact one)
  • Beam construction controlled by bool beamFromParticle
    • Using a physical source of Particle from the default Particle position by evolving a Particle a given number of times
    • Or by spreading out a given number of Particles along the ideal trajectory
  • FODO (Frodo) elements
  • Proton, Antiproton, Electron classes
• Graphics (Qt used as an openGL wrapper)
  • VBO-optimized rendering
  • Lighting (kinda)
  • Antialising
  • Framerate-independant movement
  • VSync
• Application
  • Fluid mouse and keyboard controls
  • Framerate indicator
  • Pause and speed control
• Development
  • TextRenderer: log to file or to stream
  • Custom error management (exceptions.h)
  • Centralized controls in common/globals.h
  • Centralized qmake to generate all executables

Time management

About 6-8 hours per week per person

History

All the very serious, clear and professional 300+ commit messages can be found through git

Controls

Key	Description
W	Camera forward
S	Camera backward
A	Camera left
D	Camera right
Q	Camera down
E	Camera up
Space	Pause physical simulation
Up	Increase simulation speed
Down	Decrease simulation speed

Compilation

Requirements: qt5-default Optional: doxygen (documentation)

qmake && make && bin/app.bin

This does NOT compile on the computers in CO (too old versions for g++ and qmake) !!

Software	Version in CO	Version on our computers
Qt	5.5.1	5.9.5
qmake	3.0	3.1
g++	5.5.0	7.4.0 (c++1z)
doxygen	1.8.11	1.8.13

The problem is we use inline variables, new since c++17

See docs/Conception.md for more information.

Documentation

rm doxydocs/* -r && doxygen Doxyfile
# Optional to run from command line
xdg-open doxydocs/html/index.html

Further development

• Integrate our project with Qt completely
• Fix lighting issues
• Rewrite a few classes for neater code
• Add a good accelerator editor
• Calibrate accelerator to our settings
• Add auto calibrator (adjust magnetic fields and speeds)
• Add floor/sky box
• Add emittance graph
• Add pasta texture on elements (penne + macaroni)
• Add Sextupole
• Add realistic Beam
• Research move semantics for better physics engine
• Research graphics optimizations using index buffer

Known bugs features

• Lighting comes from below in a part of the accelerator, for some reason
• On some graphics cards (e.g. integrated intel cards), the depth buffer for the drawing calls is bugged and you can see through some elements. This does not happen on nvidia cards.

Dedicated graphics card

Integrated graphics card

Lighting bug for whatever reason
