Displacement Dialog

The Displacement dialog is described below with functions for how to access it. A list of the controls on the dialog can be found in the table below.

What It Does

Allows you to generate a displacement map, using a high polygon source model and a low polygon destination model to calculate the displacement.

How to Access It

• Menubar | Objects > Generate > Displacement

• Right-click | Objects Palette > Generate > Displacement

Displacement Dialog Fields

Control	Type	What it does
Source
Object	dropdown	Select the high polygon object from which you want to calculate the displacement map.
Version	dropdown	Select the high polygon object version from which you want to calculate the displacement map.
Size	dropdown	Set the size of the selected channel on the low polygon object for which you are creating the displacement map.
Frame	entry box, slider	Set the frame from which you want to calculate the displacement map.
Destination
Version	dropdown	Select the low polygon object version to which you want to apply the displacement map.
Frame	entry box, slider	Set the frame to which you want to apply the displacement map.
Sampling
Interpolation	dropdown	Interpolation is similar to Photoshop's sampling functionality. You can select the method Mari uses to average out pixels from either: • Nearest Neighbor- selects the nearest pixel for sampling. • Inverse Distance Weighted - weights the average on the closest pixels. • Inverse Distance Weighted (Smoother) - weights the average on the closest pixels with a priority to providing smoother sampling. • Inverse Distance Weighted (Sharper) - weights the average on the closest pixels with a priority to providing sharper sampling.
Sample Count	entry box, slider	Set the number of points the search finds and combines when sampling.
Center Positions	checkbox	Choose whether or not to center the sampling position for the displacement map. This is where the Sample Count starts from.
Bleed Edges	checkbox	Choose whether or not the displacement map bleeds over the edge of patches.
Range Amount	entry box, slider	Sets the range for the search distance. The units in which this is measured are determined in Range Units.
Range Units	dropdown	The unit of measurement for the Range Amount field: • Infinite - there is no limit; Mari attempts to find a pixel in the source image data. • World Units - the maximum search distance expressed directly in world space. • Object Size Percentage - the maximum search distance is expressed as a percentage of the destination object's size.
