The RawCurvatureData.zip file contains separate files for each curvature estimation method. The data is also separated into one file for curvature data and another for normal and principal directions data. The root of the file name indicates the curvature method as follows: ANC Adjacent normal cubic fit (computed normals) ANCE Adjacent normal cubic fit (exact normals) CON1 Conic fit on 1-ring neighborhood CON2 Conic fit on 2-ring neighborhood CON3 Conic fit on 3-ring neighborhood DCO Discrete curvature operator (angle deficit) FIT1N Quadric fit on 1-ring neighborhood (natural parameterization) FIT1P Quadric fit on 1-ring neighborhood (planar parameterization) FIT2N Quadric fit on 2-ring neighborhood (natural parameterization) FIT2P Quadric fit on 2-ring neighborhood (planar parameterization) FIT3N Quadric fit on 3-ring neighborhood (natural parameterization) FIT3P Quadric fit on 3-ring neighborhood (planar parameterization) IEV Integral eigenvalue method MDCO Modified discrete curvature operator RBF1N Radial basis function fit on 1-ring neighborhood (natural parameterization) RBF1P Radial basis function fit on 1-ring neighborhood (planar parameterization) RBF2N Radial basis function fit on 2-ring neighborhood (natural parameterization) RBF2P Radial basis function fit on 2-ring neighborhood (planar parameterization) RBF3N Radial basis function fit on 3-ring neighborhood (natural parameterization) RBF3P Radial basis function fit on 3-ring neighborhood (planar parameterization) The suffix "_Verr" indicates that the file contains the error in degrees for the normal and principal curvature directions rather than the curvature magnitudes. Each row in the file corresponds to the curvature analysis of one geometry variations. The fields in this row are defined as follows: Field 0: Shape - 0=sphere, 1=ellipsoid, 2=saddle Field 1: Radius Field 2: Valence Field 3: Shape parameter A (ignored for sphere) Field 4: Shape parameter B (ignored for sphere) Field 5: Phi (mesh resolution parameter) Field 6: Delta Rc (noise normal to surface at center point) Field 7: Delta Re (noise normal to surface at 1-ring point) Field 8: Delta PHIc (movement of center point along surface toward 1-ring) Field 9: Delta PHIe (movement of 1-ring point along surface toward center) Field 10:Delta THETA (movement of 1-ring point along surface around ring) For curvature magnitude file Field 11: Mean curvature Field 12: Gaussian curvature Field 13: Maximum principal curvature Field 14: Minimum principal curvature For direction error file Field 11: Normal error (degrees) Field 12: Maximum principal curvature direction error (degrees) Field 13: Minimum principal curvature direction error (degrees)
