Function circumcenter finds the radius R and the center of the circumscribed circle of a triangle in 3D space.
Function curvature calls circumcenter for every triplet , , of neighboring points along the curve. The curvature is defined as . The curvature vector is , where is the unit vector in the direction from to the center of the circle.
Note that this local calculation is sensitive to noise in the data.
The syntax is:
[L,R,K] = curvature(X)
X: array of column vectors for the curve coordinates. X may have two or three columns.
L: Arc length
R: Curvature radius
K: Curvature vector
