Layer Maps Group

Displacement group

The Displacement group lets you displace particles in the system using the luminance values of a source layer.

A neutral gray (128, 128, 128 in 8-bit RGB) means no displacement. Colors that are darker than neutral gray will generate negative displacement and will be pushed farther away from the viewer on the Z axis. Lighter colors result in positive displacement and will be pushed closer to the viewer.

At left, a fractal noise layer. In the middle, the particle field. At right, the noise layer is applied as the Displacement map in Layer for Z, with Functionality at Individual XYZ, Map Over at XY, and Strength at 100.

Displacement > Functionality pop-up: Determines whether the source layer values will be applied across all three axes or allows you to split them apart in the event you wish to apply your map to individual axes.

• RGB to XYZ: Map the RGB channels to XYZ channels.
• Individual XYZ: Specify the layer source for each axis with separate sources in Layer for X, Y and Z controls.

Displacement > Layer for X, Y, Z pop-ups: Sets the Layer Map for the planes that are identified. These controls are enabled by the Functionality menu.

Layer for XYZ: A single pop-up that sets the Displacement Layer Map to the X, Y and Z planes. This pop-up is enabled by the RGB to XYZ option.

Layer for X, Layer for Y, Layer for Z : Three pop-ups that set the Displacement Layer Map to the X, Y and Z planes. Enabled by the Individual XYZ option.

Displacement > Strength: Controls the strength of the displacement. At value of 0, there is no effect. As you move into positive values, the displacement becomes more extreme. In negative values, the displacement will recede into the original particle field and will eventually move in the opposite direction.
