Dust plume

Billowing dust clouds rising from the ground at a point or along a line: a collapse, a quake, digging, a speeding car.

Parameters

Name	Type	Default	Range	What it does
amount (Can change over time)	number	0.6	0 to 1	how much dust is thrown up: 0 none, 0.3 a puff, 1 a billowing cloudCan change over time
at	vec2	8, 50	-1000 to 1000	where the dust rises [along, inland] metres
spread	number	10	0 to 120 m	how wide the source is: 0 a point, 100 a long line such as a car's trail or a collapsing row
rise (Can change over time)	number	3	0.5 to 12 m/s	how fast the cloud climbsCan change over time
size	number	5	2 to 10 m	how wide the billows start; they swell to about three times that
wind (Can change over time)	number	2	0 to 30 m/s	wind speed at the ground; the cloud drifts and leans with itCan change over time
windToward	number	120	0 to 360 deg	compass bearing the dust drifts toward
tint	color	#a39580	–	the colour of the dust: pale, brown or red earth
strength (Can change over time)	number	1	0.1 to 1.5	how opaque the dust isCan change over time
camera	vec2	3, -18	-600 to 600	where the camera stands [along, inland] metres; the effect gathers ahead of it
facing	number	20	0 to 360 deg	compass bearing the camera faces: 20 is the street looking at home, 210 out to sea
level (Can change over time)	number	0	-20 to 60 m	height of the ground or water the effect lies on, over today's sea; follow the sea as it risesCan change over time
hazeRaise	number	0	0 to 2	how far the dust thickens the town's air, once at a shot's start; 0 leaves the haze alone
seed	integer	6	0 to 99	which random pattern the particles fall in
