Particle System Room
Particle System Room
The Particle room is a room in which the user is allowed to interact with gravity defying ions.
Left alone, the charges provide a calming visual. Unfortunately, due to scale of these physics the applied force had to be reduced in order for the system to hand smooth animations of the particles as well as allow them to be user interactable.
Coulomb Forces applied to a field of Cations and Anions. Cations are denoted by red spheres and are positively charged, Anions are black and negatively charged.
Messing around with Ion from the particle room.
Users after free to interact with any and all the ions they can get their hands on.
They can try to create stable shapes, experiment with orbits, or even take advantage of the attractive forces to attract more that have gone into hard to reach places.
Ultimately, this is meant to be a calming and fun room with a bit of electrostatics in the background to help cement the users idea of how the attractive and repulsive forces interact.
Interactive Electrostatic Sprayer
Interactive Electrostatic Sprayer
The interactive electrostatic sprayer sprays a positively charged spray.
By experimenting with the specially made anion and caution you can see how the spray moves to avoid the cation and is attracted to the anion. If you are up for the challenge, feel free to go to the particle room to get additional charges to experiment with the spray. (as above)

Checking out how the spray sticks to the Stanford Bunny.
VFX Electrostatic Sprayer
VFX Electrostatic Sprayer
The VFX graph approch has the greatest potential for presenting sprays. It is not uncommon for a spray to have over 10,000 drops per mm^3 in a minute (or even seconds for some). VFX graph allows Unity to use the systems graphics cards and can reach particle counts in the millions.
This simple simulation also shows that some level of custom behavior can be added to the particles.
Additional development needs to be done to create more realistic sprays and to see what depth the graph make be taken towards realism.
Cation Wand
Cation Wand
To further explore the forces within the particle room (or the particle based spray) a wand is provides to create temporary tracer cations. These tracers are coded such they only follow the forces present in the system, rather than contribute any forces of their own.
Cation Wand in use to see to movement of potential cation additions to a bundle.
