LookupGeo

The LookupGeo node lets you use lookup curves to modify the shape of your 3D geometry objects. It offers you direct global control over each of the vertex x, y, and z values respectively. You can, for example, only modify all the y values without touching the x and z values.

You change the different vertex values (x, y, or z) by modifying their associated 2D curves in lookup tables (LUTs). The x axis in the LUT represents the current vertex value, and the y axis the new vertex value. By default, the curve is a diagonal line where all the points in the curve have the same value on the y axis (the new value) as they do on the x axis (the current value). Because both x and y values are the same, there is no change in the object’s shape.

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The 3D geometry object whose shape 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.

Control (UI)	Knob (Scripting)	Default Value	Function
LookupGeo Tab
display	display	unchanged	Adjusts the display characteristics of the 3D object. These settings don’t affect the render output of the scene; these are for display purposes only in the 3D Viewer. • off - hides the 3D geometry object. • wireframe - displays only the outlines of the object’s geometry. • solid - displays all geometry with a solid color. • solid +wireframe - displays the geometry as solid color with the object’s geometry outlines. • textured - displays only the surface texture • textured +wireframe - displays the wireframe plus the surface texture. • unchanged - doesn't change the object's display mode. The Viewer can override this setting.
selectable	selectable	enabled	When enabled, you can make selections as normal in the Viewer. When disabled, points cannot be selected or changed.
render	render_mode	unchanged	Sets how the object will render. This control is independent from the display selection, but has the same settings.
LUT curves	lut	N/A	Selects the curve you want to modify. Choose X, Y or Z. For example, you’d select Z to only modify the vertex z values. Adjust the curve as necessary by dragging. To insert points on the curve, Ctrl/Cmd+Alt+click on the curve.
reset	N/A	N/A	Resets the selected curve(s) to their initial values.
