Fit shape to point list
If at least 3 points are defined, a fitting shape can be computed and added to the project.
According to the number of the selected points a plane, a cylinder, a sphere, a cone or a circle can be fitted.
For each shape, a default set of fitting parameters can be adopted or modified to interpolate the points.
Among the selected points, the RANSAC algorithm randomly selects X points and tries to fit the geometric shape on them.
The algorithm then iterates this procedure N times keeping the best result that it found among all attempts. The quality of the fitting is given by how many points (out of the selected ones) are sufficiently close - and therefore belonging - to the geometric shape (inliers).
The maximum value of X is given by the Maximum points used for fitting [#] parameter.
The RANSAC minimum iterations [#] parameter defines the minimum number of attempts N that the algorithm must make before considering the geometric shape correctly fitted.
Inliers maximum distance [m] defines the maximum distance within which a point is considered to belong to the geometric shape.
A special button allows you to reset to default parameters at any time.
