This is an auxiliary program to visualize high energy particle collision events right after they collide.

Examples

A short clip showing the basic funcionality of the program

A short clip of the moving particles (without any user input)

Details

The program takes in *.hepmc files, and allows user to interactively observe the event from different position and angle. The user can also manipulate the flow time, namely foward/freeze/backward in time, or make time move faster or slower. The coloring scheme can also be changed to highlight any type of particles.

The color scheme is listed as follows:

• White: Gauge bosons (photons, Z, W, etc.)
• Red: Leptons and neutrinos (electron, positron, muon, etc.)
• Yellow: Baryons
• Green: Mesons
• Blue: Quarks

Keyboard control

• Arrow keys and Home, End: move the camera (observer) around.
• Page up/down, Insert, Delete: rotate the viewing direction.
• Q/W/E: make time go backward, freeze or forward, respectively.
• A/S/D: slow down time, reset speed, and increase time flow, respectively.
• C: change color scheme.
