Fluid 2D

Description

This effect displays a fluid looking effect at the coordinates contained in the input array.

Properties

Array properties

Any properties in the input array that matches the name of these properties will be used and displayed accordingly.
These properties can also be shown as inputs on the node by toggling the icon.
In the dropdown menu you can choose how values from the array interact with values from the Editor panel or the input between : Replace, Add or Multiply.
More information can be found on the GPU Multi category page.

• Array : The array of positions to draw at.
  Default : Empty value

• Radius : The default radius of the fluid drawn at the position. A radius of 0 will hide the fluid while a radius of 1 will take up most of the screen.
  Default : 0.04

• Color : The default color of the fluid.
  Default : White 255 / 255 / 255 / 255

• Persistence : The ability of the fluid to persist over time and then gently dissolve. A value of 0 means no persistence while a value of 1 means full persistence (no dissolve). Values over 1 will keep generating fluid even after the input is gone.
  (Default : 0.98)

• Diffusion : The ability of the fluid to diffuse itself over an area or stagnate at the point of input. A value of 0 means the fluid will not diffuse and a value of 1 means the diffusion will be maximum.
  (Default : 0.98)

• Vorticity : The ability of the fluid to create vortices at the point of input. This requires some amount of diffusion to be perceptible. A value of 0 means no vorticity while a value of 1 will create a high amount of vortices. Values over 1 may produce erratic behaviours
  (Default : 0.98)

Global properties

This node does not have any global properties.

Inputs

This lists only the inputs present by default at the creation of the node. The inputs that appear can be tuned by toggling the button in the Editor panel.
