Analysis > Edit Curvature Spectrum adjusts the characteristics of the Curvature Map that appears on a Polygon object in the Shape phase if the Curvature Map checkbox is activated in the Primitives Manager. The Curvature Map is a color-coded representation of the degrees of curvature on a Polygon object in the Shape phase.
Convex curvature is represented by a color on the negative part of the spectrum. Concave curvature is represented by a color on the positive part of the spectrum.
Spectrum group - contains the parameters that describe the curvature spectrum.
Color Segments integer field (must be an odd value) - specifies the number of unique colors by which curvature will be represented. Relatively flat portions of the object are represented by light green.
Max. Positive decimal field - specifies the convexity beyond which curvature will be reported as maximal (red). When you set Max. Positive, the software assumes you want a “symmetrical spectrum” and changes Max. Negative to the same value with a negative sign. To create a non-symmetrical spectrum, simply change Max. Negative after adjusting Max. Positive.
Min. Positive decimal field - specifies the maximum convexity of “relatively flat”
Min. Negative decimal field - specifies the maximum concavity of “relatively flat”
Max. Negative decimal field - specifies the convexity beyond which curvature will be reported as maximal (dark blue).
Decimal Places integer field - specifies the precision to which curvature is measured.
OK button - saves the curvature spectrum.
