Smoke Flow – Description

– The Smoke Flow force field creates a force based on a Smoke simulation air flow.
– It applies the smoke simulation air flow velocity as a force to other simulations that use force fields. To use it you need to add a Smoke Flow force field and select a domain object for it.
– For example fire sparkles could realistically flow along the air turbulence near the simulated fire.

Turbulence – Description

– A Turbulence force field creates a random & chaotic 3D noise effect, similar to jets of water or geysers under the ocean.

Boid – Description

– As with most artificial life simulations, Boids is an example of emergent behavior; that is, the complexity of Boids arises from the interaction of individual agents (the boids, in this case) adhering to a set of simple rules.

– The rules applied in the simplest Boids world are as follows:

– Separation: Steer to avoid crowding local flock mates.
– Alignment: Steer towards the average heading of local flock mates.
– Cohesion: Steer to move toward the average position (center of mass) of local flock mates.

– More complex rules can be added, such as obstacle avoidance and goal seeking.
