ApplyDisplacement

The ApplyDisplacement command constructs a displacement display mesh for surfaces, polysurfaces, or meshes.

Gold color material (left), gold color material with bump map (center), gold color material
with displacement map (right).

Note

●

The displacement map can be a procedural or an image texture.

●

Displacement appears as an object property for the surface.

●

The displacement map differs from a bump map set by the rendering material in that the displacement mesh is a real object with edges that produce real highlights and shadows. The illustrations use the same image for the bump and the displacement.

Steps

Select objects to apply displacement mapping to.

Specify a texture.

Specify the displacement settings options.

Command-line option

RemoveAll

After displacement is applied, removes displacement mapping from all objects in the model.

Displacement Properties

Manages surface displacement properties for the selected objects.

Basic settings

Enables the displacement mapping display.

Texture

Specifies a procedural texture or image file used to map the displacement.

Import from file

Opens a Rhino Texture file (.rtex) or supported image formats.

Note

Rhino supports the following file formats:

Transparency is not supported in these formats:

●

JPEG - JFIF Compliant (*.jpg, *.jpeg, *.jpe)

●

Windows Bitmap (*.bmp)

Transparency is supported in these formats:

●

DDS files (*.dds)

●

HDRi files (*.hdr, *. hdri)

●

OpenEXR files (*.exr)

●

Portable Network Graphics (*.png)

●

Tagged Image File Format (*.tif, *.tiff)

●

Truevision Targa (*.tga)

New

Creates a new displacement texture.

Edit

Edits the current displacement texture settings.

Duplicate

Duplicates the current displacement texture settings.

Mapping channel

Mapping channel number for the displacement mapping.

Displacement

Black point

Amount of displacement (in currently used units) for black colors on displacement texture. Can be any number.

White point

The amount of displacement for the white color in the procedure or image.

Mesh detail settings

Initial quality

Specifies how densely the object is subdivided and displacement texture is sampled initially. Using too low initial quality may result in loss of some features in the displacement. Too high initial quality makes displacement process unnecessarily dense and slow.

Low

Medium

High

Very High

Extremely High

Max faces

Runs a mesh reduction as a post process and simplifies the result of displacement to meet the specified number of faces.

Fairing

Straightens rough feature edges. This is similar to anti-aliasing. The value specifies the number of passes.

Advanced settings

Post weld angle

Specifies the maximum angle between face normals of adjacent faces that will get welded together.

Mesh memory limit (MB)

Specifies in megabytes how much memory can be allocated for use by the displacement mesh.

Refine steps

After the initial subdivision and displacement texture sampling further refinement takes place. The value specifies the number of refinement passes.

Refine sensitivity

Specifies how sensitive the divider for contrasts on the displacement texture is. Specify 1 to split all mesh edges on each refine step. Specify 0.99 to make even slight contrasts on the displacement texture cause edges to be split. Specifying 0.01 only splits edges where heavy contrast exists.
