4.5.1.1 Volumetric Curvature

Returns Curvature properties from a SteeringCube

At every sample location, a 'virtual local horizon' is constructed on which the curvature is calculated (from the SteeringCube). This 'local horizon' is converted to depth in time surveys, which is why a velocity input is required. The output attribute is a 2D dataset or 3D volume that may be applied (projected) along horizons. Using a large stepout with a detailed SteeringCube in this attribute gives similar results as using a strongly filtered SteeringCube but with a small stepout. However the attribute runtime will be different.

For further detail, including descriptions of the output options, below, please refer to Curvature Analysis.
