Particle Physics

Particle Physics define the properties of particles which determine how they interact with their Environment .

(Bowling balls and feathers set to their own Mass and Air Resistance will react differently to the same Air Density, Gravity and Wind in the Environment)

Mass

Assign a Mass value to your particles to approximate the amount of matter they contain. This will affect how forces like gravity and wind move the particles. Values range from 0.1 to 1000, with a default setting of 10. Particles can never have a mass of zero.

Mass Random

Mass Random sets the randomness for Mass, as a percentage. Higher values mean the randomness is higher, and the particles have more variation in mass.

Size Affects Mass

When turned all the way up to 100%, how large or small the particles are will affect how much mass they have. At the default setting of 0%, there is no difference to the mass if the size of the particles varies.

Air Resistance

Also referred to as drag, Air Resistance is the result of collisions of the object's leading surface with air molecules. By changing the Air Resistance of your particles, you will affect how much they respond to Environment controls such as Gravity, Wind and Air Turbulence. Values range from 0 to 100, with a default setting of 0.5.

NOTE Air Resistance settings can have a strong effect on how other controls are working. If set very high, the particles may not be able to get through the Air Density you have set, and could sit in place. If set to zero, nothing will alter their path, such as Wind. This is why the default value is 0.5, to allow for enough air resistance to be in place for your particles to at least react to their environment.

Air Resistance Random

Sets the randomness for the particle’s Air Resistance, as a percentage. Higher values mean the randomness is higher, and the particles have more variation in air resistance.

Size Affects Air Resistance

When turned all the way up to 100%, how large or small the particles are will affect how much air resistance they have, as if their surface area has increased or decreased. At the default setting of 0%, there is no difference to the air resistance if the size of the particles varies.

Rotational Air Resistance

When set above the default level of 0, Air Resistance will add some rotational movement to your particles as they are buffeted by forces from their environment.
