Particle Sys
attribbutes
emission (speed,spread,rate)
-
lifespan (inf, const, var)
-
-
-
-
origin
collection of many small particles that together rep a fuzzy object. over period of time, particles generated into sys, change within sys, and die in sys.

Life Cycle
-
Dynamics
-
each attr can be specified by f(time) = ...OR f(time, other_particles) = ..
-
Criteria
Collection of Particles - 1 . more indiv. particles. each has attr directly / indirectly affect particle behaviour & ultimately how/where it is rendered.
Stochastically def. attr
has random element via stochastics limits (bound, variance, distro). random elem controls particle attr.
sim
2d - Sprites
-
(pos, dim) = (anchor point, sprite dimension)
-
render
running all 3 stages simultaneously will result in static (not animated) particles e.g. hair / fur / grass
