Smoke Simulator
Simulating smoke in AWSIM may be useful when one wants to simulate exhaust gases from vehicles, smoke from emergency flare, etc.
In Unity, it is common to use Particle System to simulate smokes. However, smoke simulated by Particle System cannot be sensed by RGL in AWSIM although in reality, smokes are detected by LiDAR.
Smoke Simulator
was developed to simulate smokes that can be detected by RGL in Unity.
Smoke Simulator
works by instantiating many small cubic GameObjects called Smoke Particles
and allows each particle to be detected by RGL.
This document describes how to use the Smoke Simulator
.
Setting Smoke Simulator
1.Create an empty GameObject
2.Attach SmokeGenerator.cs
to the previously created GameObject.
3.Adjust the parameters of the SmokeGenerator
as described below:
Max Particle
: Specifies the maximum number of particles created by theSmoke Generator
Particle Range Radius
: Specifies the radius of a circle, centered at the GameObject, which defines the region in whichSmoke Particles
are generated inParticle Size
: Specifies the edge of aSmoke Particle
Average Lifetime
: Specifies the average lifetime of aSmoke Particle
-
Variation Lifetime
: Specifies the variation of lifetime ofSmoke Particles
.The lifetime of a
Smoke Particle
is calculated as follows:`lifetime` = `Average Lifetime` + Random.Range(-`Variation Lifetime`, `Variation Lifetime`)
-
Physics
: These parameters can be adjusted to specify the behavior of the smoke particles.Initial Plane Velocity
: Specifies the velocity of aSmokeParticle
in the x-z planeInitial Vertical Velocity
: Specifies the velocity of aSmokeParticle
in the vertical directionPlane Acceleration
: Specifies the acceleration of aSmokeParticle
in the x-z planeVertical Acceleration
: Specifies the acceleration of aSmokeParticle
in the vertical direction
4.(Optional): You may also specify the Material
of Smoke Particles
. If this field is unspecified, a default material is used
