Emitter : Emission Circle

“Circle” is an area emitter. Emitters define the point of particle creation in 3D space, while the particles are part of the "Fluid" container. Emitters can be scaled, rotated, and translated like objects; an arrow indicates the direction of emission.

Volume

This feature creates a defined volume of particles. The size of this volume is defined by the emission area and the value entered here.

Speed

Here the particles' initial speed is defined in metres per second. Higher values will generate more particles per frame. The number of emitted particles also depends on the fluid's “Resolution” settings. A value of 0.0 stops the emission of particles.

Vertical Random

To avoid regular emission, it is possible to randomly displace the particles. The parameter accepts any positive value and 0.

Horizontal Random

To avoid regular emission, it is possible to randomly displace the particles. The parameter accepts any positive value and 0.

Side Emission

Normally the particles are poured out along the emission axis, but it is possible to emit the particles from the emitter's edge. Then, the circle’s inner area remains empty.

Ring Ratio

You are able to define a ring from where the particles will be emitted. Small values create a larger emission area, higher settings are responsible for thin rings. The value's range is between 0 and 1.
