Inputs and Controls
|
Connection Type |
Connection Name |
Function |
|
Input |
unnamed |
The 3D geometry object you want to modify. This can be a Card node, for example. If you want to modify several objects together, you can also connect a MergeGeo node here. |
|
displace |
The image you want to use to modify the 3D geometry object. |

channels |
channels |
rgb |
The displace input’s channels to use for the displacement value. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. |
|
source |
source |
luminance |
The source channel you want DisplaceGeo to get a displacement map from. For example, if you selected rgb or rgba from the channels dropdown menu, you can use the red, green, or blue channel, or the pixel luminance as the source. • luminance - create a displacement map from luminance values. • red - create a displacement map from red color values. • green - create a displacement map from green color values. • blue - create a displacement map from blue color values. • alpha - create a displacement map from the alpha channel values. • rgb absolute - move your geometry object’s vertices to the values in rgb. • rgb relative - move your geometry object’s vertices on the x, y and z axes by the amounts in rgb. |
|
scale |
scale |
0.1 |
Increase or decrease the scale of the displacement. The higher the value, the bigger the displacement. |
|
weight |
weight |
1, 1, 1 |
To give x, y, and z different weightings, enter new weights the weight fields. By default, each weighting is set to 1. If you don’t want to make changes to a value, set its weight to 0. |
|
offset |
offset |
0, 0, 0 |
To offset x, y, and z values from the center of the geometry object, enter the value by which you want to offset them in the offset fields. For example, if you enter 0.5 in the offset y field, 0.5 is added to the y value. |
|
filter size |
filter_size |
5 |
Change the size of the filtering applied to the image before the displacement. |

filter |
filter |
Parzen |
Select the filtering algorithm to use when remapping pixels from their original positions to new positions. This allows you to avoid problems with image quality, particularly in high contrast areas of the frame (where highly aliased, or jaggy, edges may appear if pixels are not filtered and retain their original values). • Impulse - remapped pixels carry their original values. • Cubic - remapped pixels receive some smoothing. • Keys - remapped pixels receive some smoothing, plus minor sharpening (as shown by the negative -y portions of the curve). • Simon - remapped pixels receive some smoothing, plus medium sharpening (as shown by the negative -y portions of the curve). • Rifman - remapped pixels receive some smoothing, plus significant sharpening (as shown by the negative -y portions of the curve). • Mitchell - remapped pixels receive some smoothing, plus blurring to hide pixelation. • Parzen - remapped pixels receive the greatest smoothing of all filters. • Notch - remapped pixels receive flat smoothing (which tends to hide moire patterns). • Lanczos4, Lanczos6, and Sinc4 - remapped pixels receive sharpening which can be useful for scaling down. Lanczos4 provides the least sharpening and Sinc4 the most. |
|
attrib name |
uv_attrib_name |
uv |
Change the name of the attribute that’s used as the vertex’s UV coordinates to find the image pixel. Normals are stored as a named attribute of a piece of geometry. • Cf - surface color • N - normal • PW - world-space point • uv - texture coordinates • vel - point velocity. |
|
recalculate normals |
recalc_normals |
enabled |
After the displacement, check this to recalculate the normals, which usually aren't correct after the vertices have been moved. |
