Layer Intensity

Field - Field where particles move toward a certain color in a 2D layer

A layer based field that uses a target color to move particles toward, or around.
By changing the directional strength, the particles will be attracted (or repulsed, using a negative value) to a specific color in the layer.
By changing the orthogonal strength, the particles will rotate around that specific color.
To choose the target color, you can use the color selector, which by default is based on the most luminous color.
Here is a little experiment using cat spritesheets, and this field with a Noise layer Generate a possibly animated noise image Read More as intensity map:

Parameters

  • 2D Generator: Select the 2D Generator The part of a 2D layer that generates the image Read More
  • Color selector used to define what attracts particles

    Parameters common to all Elements

    • Activation State: The loading status of the color selector. It can be loaded , enabled by not loaded or unloaded
    • Activation State: The activation status of the color selector. It can be active , enabled by not active or inactive
    • Associate a color label to your color selector to make it easily locatable
    • Activate this to keep only this color selector active and hide all other color selectors in same location
    • Activation State: The editabiliy status of the color selector. It can be locked directly , locked indirectly or editable
    • Element: Select a preset to apply on the color selector
    • Warnings and errors associated to this color selector
  • Number lookups of the layer intensity
  • Influence radius of the layer intensity

Parameters common to all Layer Based Fields

  • 2D Generator: Select the 2D Generator The part of a 2D layer that generates the image Read More
  • 3D Placement: Placement of the layer projection in space
  • Type of mapping (projection) of the layer in space

    Parameters common to all Elements

    • Activation State: The loading status of the 3d mapping. It can be loaded , enabled by not loaded or unloaded
    • Activation State: The activation status of the 3d mapping. It can be active , enabled by not active or inactive
    • Associate a color label to your 3d mapping to make it easily locatable
    • Activate this to keep only this 3d mapping active and hide all other 3d mappings in same location
    • Activation State: The editabiliy status of the 3d mapping. It can be locked directly , locked indirectly or editable
    • Element: Select a preset to apply on the 3d mapping
    • Warnings and errors associated to this 3d mapping
  • Directional influence on particles (how much they go toward the direction given by the field). How the particles will move in direction parallels to the projected layer.
  • Orthogonal influence on particles (how much they go around the direction given by the field). How the particles will move in direction perpendicular (normal) to the projected layer
  • Influence the particles forces (change their velocity and direction). Modify the force of particle = acceleration (f = m * a Newton second law)
  • Influence the particles velocity only (accelerate or slow them down without changing their direction). Modify the velocity of the particle, physically the only thing that can modify the velocity of an object is the sum of the forces that's why this parameter should not be used to have physically correct movements
  • Influence the particles position directly, without changing its forces. Modify the position of the particle, same remarks for than the velocityStrength
    Warning, influencing directly the position can make the particles go through surfaces without colliding with them!
