This is another three-dimensional emitter and the particles are radially emitted from the outside of the cylinder. The cylinder is represented by two circles, which define its length. Radius and height can be controlled via the emitter’s "Scale" settings. Please note that it is not possible to fill the emitter or create volumes. If you want to create a filled object, please use a "Cylinder" node and a "Fill Object" emitter.

Speed

Here you can define the emitter’s initial speed. Higher values will generate more particles per frame. Faster particles act with stronger forces on other particles or objects. The number of emitted particles also depends on your resolution settings. A value of 0.0 disables the emission of particles. This value can be animated either with keyframes or expressions. "Speed" is measured in metres per second [m/s].

V/H random

By default the particles are regularly emitted, showing a kind of pattern. The reason is that the particles are emitted as a homogeneous stream. To avoid and suppress this pattern, it is possible to randomly displace the particles with these functions. The values should range between 0 and 1, but can be higher, as well. “V” stands for vertical, while “H” means horizontal.
