Determines the best spherical fit on a cloud of points in 3D.
x coordinates of the points of the cloud.
y coordinates of the points of the cloud.
z coordinates of the points of the cloud.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Calculated midpoints of the given cloud.
Calculated radius of the given cloud.
Error information.

This node calculates the best spherical fit by finding x0, y0, z0 and r that minimize the objective function:
This leads to a simple linear equation in x0, y0, z0 where (xi, yi, zi) are the given points, (x0, y0, z0) is the unknown midpoint, and r is the unknown radius.

Desktop OS: Windows
FPGA: Not supported
Web Server: Not supported in VIs that run in a web application
