Asset overview
What this node setup does
CURVE INPUT. Resamples each spline uniformly and estimates discrete curvature as turning angle divided by average adjacent chord length. Endpoints of open curves get curvature zero and valid false. Cyclic curves wrap. Stores omni_curvature, omni_curvature_valid and omni_curvature_color; optional tubes give visible output. Radius/display range are local units. Degenerate segments invalid; approximation depends on sample count. Not analytic spline curvature. Mesh input passes through unchanged. See Utility Analysis Examples scene. AI preview is illustrative.
Source and setup notes
Source asset name: OMNI - Curve Curvature Pro
Collection: 07 Utilities/Analysis Tools
Structural inspection used Blender 5.2.0 LTS. Other releases and render engines require separate checks.
How to approach this asset
- Check the source notes for the expected mesh, curve, field, shader or World context.
- Start with a disposable scene and a suitable input. Inspect required object, material or collection inputs.
- Adjust one documented control at a time. Evaluate the result before using it in a production project.
