Houdini 20.0 Nodes Geometry nodes

Labs Measure Curvature 2.0 geometry node

Generates Point Colors based on the Curvature of the Model

Measures the Curvature of a model and outputs it as Point Colors.

Handy for all types of calculations, including scattering and polyreduction. Curvature is one of the fundamental mesh properties and is generally useful.

By Default, green will represent Convex colors and Red will represent Concave colors. Unless Single Color Value is set.

Note

This node doesn’t still make use of the new Measure 2.0 SOP capabilities.

Parameters

Curvature Values

Calculate Per Piece

Toggle the calculations as a whole or as diconnected pieces

Method

Dropdown with several algorithms (some provided by community user Petz)

Voxel Size

For Voxel based calculations, adjust the size of the voxel grid

Convex Adjustment

Range Scale

Multiply the range of the Convex Colors, similar to an intensity control, but before contrast/intensity are run

Contrast

Tighten the contrast on the colors

Intensity

Another multiplier on the colors

Blur Amount

Optional Blur to soften the colors

Concave Adjustment

Range Scale

Multiply the range of the Convex Colors, similar to an intensity control, but before contrast/intensity are run

Contrast

Tighten the contrast on the colors

Intensity

Another multiplier on the colors

Blur Amount

Optional Blur to soften the colors

Extra Settings

Visualize As Color

Output the Paramters as the Cd attribute

Single Color Value

Toggle between the red/green output or a single value

Fit To 0-1

Clamp the output between 0-1
