curvlev3new
algorithm
- extracts curvature values on a 3d surface from a 3D matrix:
mean curvature, gauss curvature and principal curvatures - calculates curvature values of a surface given in implicit form (Article of Hughes)
- note: curvlev3new needs curvature values in the matrix;
- use curv3new to calculate the curvature values in the matrix
syntax
[var1,var2,var3,var4]=curvlev3new(X,Y,Z,KG,H,K1,K2,fdefine,level,s)
example for input
[var1,var2,var3,var4]=curvlev3new(X,Y,Z,KG,H,K1,K2,CO2,0.03,'abs')
