The initial velocity from the grid.
The movement of the emitter (vertex, face or object)).
The movement according to the gravity or air resistance.
Influence of the force fields such as wind, vortices or
guided through a curve.
Interaction with other objects such as collisions.
Slow motion physics "softbody" (only in systems of hair
particles)8.
Or even the manual processing.
The particles can be represented as:
Halos (for the preparation of flame, smoke, clouds)
Strands (used in the development of hair, skin, grass), the
full form of a string will be displayed as a string or
filaments, these filaments can be manipulated (comb, cut,
move, etc..) directly in Blender.
