Rain
This effect is used to add raindrops to an image: basically, different types of rain (from drizzle to downpour), and by adjusting some parameters even snow (AKVIS Snow preset).
Note: The effect will be applied only in a selected area! Use the  ,  and  tools to make a selection.
Rain Effect in AKVIS NatureArt
In Settings Panel you can adjust the parameters for the Rain effect:
- Density. This parameter sets the density of the rainfall. At lower values the effect appears as drizzle, the raindrops are sparse and are far from each other. At higher values is is similar to a "wall" of rain.
|
|
| Density = 5 |
Density = 15 |
- Length. This parameter defines the degree to which drops are lengthened. It also acts as a constraint on length. The length of drops may be different, but their length will not exceed the specified value.
|
|
| Length = 10 |
Length = 40 |
- Scale. This parameter affects the size of raindrops. If Length is changed the raindrops will only change in length, but changing this parameter affects the size of raindrops in all geometric directions. The higher the value, the larger the raindrops.
|
|
| Scale = 1 |
Scale = 3 |
- Angle. This parameter determines the direction of falling raindrops and leads to the creation of another effect - wind. If the value is equal 90, rain falls vertically (no wind). At values less than 90 the rain falls at a right angle (wind is blowing from right to left). At values higher than 90 it falls at a left angle (wind is blowing from left to right).
Note: |
If you watch through a window at how rain falls, it's clear to see that wind deforms raindrops: smearing them on the glass, stretching them. It does the same thing in the air. Therefore, to achieve the most realistic effect it is necesssary to change both the Angle and Length of the raindrops. The greater the slope, determined by Angle, the stronger the force of the wind and the stronger the effect of Length. |
- Dispersion. This parameter determines the deviation of raindrops from the general direction of rainfall (which is based on Angle).
When the value is set to 0 all raindrops fall at the same angle.
At higher values raindrops will deviate from the direction specified by Angle. The higher the value, the greater the deviation of the raindrops' pattern.
| The value of "Dispersion" has been set to 0 |

Angle = 90
Length = 10

Angle = 60
Length = 15
|
Angle = 135
Length = 25
|
| The value of "Angle" has been set to 90 |
|
|
|
| Dispersion = 0 |
Dispersion = 15 |
Dispersion = 35 |
- Transparency. This parameter affects the translucency of raindrops. At higher values, their color fades and more of the image is visible through them.
|
|
| Transparency = 5% |
Transparency = 40% |
