# Curvature Texture

The **Curvature Texture** node can be used to alter the look of the edges of a surface (figure 1).

Figure 1: The Curvature Texture node is used to mix Red and Blue RGB Color nodes on a

## Curvature Texture Parameters

**Mode** - Determines the type of curvature to sample.

**Strength** - Determines the overall strength of the curvature effect.

**Radius** - Specifies the maximum area affects by the curvature effect.

**Radius Map**- Determines the proportion of the maximum area affected by the curvature effect.

**Offset** - Specifies the offset from the surface used to sample the neighboring geometry.

**Tolerance**- Determines the tolerance for small curvature and small angles between polygons

**Spread** - Controls the ray direction with respect to the normal of the surface where 0 means the curvature is sampled straight in the direction of the surface normal, and 1 means the sampling rays are shot perpendicular to the surface normal.

**Include Object Mode** - Determines which objects should be included in calculating the curvature value.

**Invert Normal** - Inverts the normal direction when calculating the curvature value.
