This emitter creates particles within a triangular area and has exactly the same properties and restrictions as the “Square” emitter.
Volume
This feature creates a defined volume of particles. The dimensions of this volume consist of the emitter’s scale settings and the value entered here, based on RealFlow’s grid units. By activating this option, the emitter’s speed value will be set to 0.0 automatically.
Speed
Here you can define the particles' initial speed. Higher values will generate more particles per frame and 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.
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.
Side emission
Normally the particles are poured out along the emission axis. With this parameter set to “Yes”, a radial emission is performed from the outline of the emitter and the circle’s inner area remains empty.
