DyEmitters - Linear
- thomas (Unlicensed)
"Linear" is a two-dimensional emitter in the shape of a straight line. You can position (W key) and rotate (E) this emitter, but for scale changes we recommend the emitter's “Length” parameter.
Type
Toggle the emitter's type with this drop-down menu. The following parameters and the viewport representation will be updated according to your selection. Bear in mind that type changes will change the emitter's and fluid's behaviour completely.
Height
This creates a rectangle filled with particles. "Height" is given in metres. The particles will still have an initial velocity determined under "Speed". To avoid this, set "Speed" to 0.
Length
You should change the emitter’s length with this parameter, instead of using the → “Scale” settings under "Node". "Scale" is available, but works like a multiplier, if “Length” is activated: an emitter with “Length” = 3.0 and “Scale X” = 2.0 has a total length of 6 units. The value is given in metres.
Speed
Here the particles' initial speed is defined in metres per second. 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 the domain's "Resolution" settings. A value of 0.0 → stops the emission of particles.
V random
To avoid regular emission, it is possible to randomly displace the particles with these functions. The parameter accepts any value positive value and 0. “V” stands for vertical.
H random
To avoid regular emission, it is possible to randomly displace the particles with these functions. The parameter accepts any value positive value and 0. “H” stands for horizontal.
