compute curvatures (Gauss and mean) of a Polydata object
<p>
<a class="el" href="a00349.html" title="compute curvatures (Gauss and mean) of a Polydata object">vtkCurvatures</a> takes a polydata input and computes the curvature of the mesh at each point. Four possible methods of computation are available :<p>
Gauss Curvature discrete Gauss curvature (K) computation, <img class="formulaInl" alt="$K(vertex v) = 2*PI-\sum_{facet neighbs f of v} (angle_f at v)$" src="form_9.png"> The contribution of every facet is for the moment weighted by <img class="formulaInl" alt="$Area(facet)/3$" src="form_10.png"> The units of Gaussian Curvature are <img class="formulaInl" alt="$[1/m^2]$" src="form_11.png"><p>
Mean Curvature <img class="formulaInl" alt="$H(vertex v) = average over edges neighbs e of H(e)$" src="form_12.png"> <img class="formulaInl" alt="$H(edge e) = length(e)*dihedral_angle(e)$" src="form_13.png"> NB: dihedral_angle is the ORIENTED angle between -PI and PI, this means that the surface is assumed to be orientable the computation creates the orientation The units of Mean Curvature are [1/m]<p>
Maximum (<img class="formulaInl" alt="$k_max$" src="form_14.png">) and Minimum (<img class="formulaInl" alt="$k_min$" src="form_15.png">) Principal Curvatures <img class="formulaInl" alt="$k_max = H + sqrt(H^2 - K)$" src="form_16.png"> <img class="formulaInl" alt="$k_min = H - sqrt(H^2 - K)$" src="form_17.png"> Excepting spherical and planar surfaces which have equal principal curvatures, the curvature at a point on a surface varies with the direction one "sets off" from the point. For all directions, the curvature will pass through two extrema: a minimum (<img class="formulaInl" alt="$k_min$" src="form_15.png">) and a maximum (<img class="formulaInl" alt="$k_max$" src="form_14.png">) which occur at mutually orthogonal directions to each other.<p>
NB. The sign of the Gauss curvature is a geometric ivariant, it should be +ve when the surface looks like a sphere, -ve when it looks like a saddle, however, the sign of the Mean curvature is not, it depends on the convention for normals - This code assumes that normals point outwards (ie from the surface of a sphere outwards). If a given mesh produces curvatures of opposite senses then the flag InvertMeanCurvature can be set and the Curvature reported by the Mean calculation will be inverted.<p>
