Curvature
Curvature
Use Curvature to extract convex and concave response from shape or height information. It is valuable for smart masks such as edge wear and cavity dirt.
Availability
This node requires Pro.
Common uses
- Use analysis outputs as masks or support maps in blend chains.
- Pair with levels or threshold nodes to isolate useful map ranges.
Input ports
-
input -
Usually expects a structured grayscale or height-like input.
Output ports
-
out -
Outputs one or more analysis maps depending on node type.
Parameters
| Parameter | Type | Default | Range or values |
|---|---|---|---|
| Radius | int | 1 | 1 to 8 |
| Intensity | float | 1 | 0 to 5 |
| Smoothness | int | 0 | 0 to 10 |
| Invert | bool | false | - |
| Mode | enum | both | both, convex, concave |
Behavior
- These nodes compute derived data from shape and height information.
- Outputs are often best consumed by downstream utility and mixing nodes.
Common mistakes
- Analysis nodes can be sensitive to noisy or low-contrast inputs.
- Map interpretation changes with downstream color-space assumptions.
