# ExtractPlane3D Vision Data Access functions

This section lists the available 3D Vision Data Access functions that get values from the results of a Planes3D structure.

Note: Each of the following functions references the results of a Planes3D structure for the first parameter. Index (zero-based) determines which result 3D plane of the Planes3D structure you want to reference. If you do not specify the index, the index defaults to zero, meaning the function returns the first plane.

Function | Description
GetNFound(Planes3D) | Returns the number of found planes.
GetNumInliers(Planes3D, [Index]) | Returns the number of inliers in the plane specified with the index number.
GetPlane(Planes3D, [Index]) | Returns the extracted Plane3D structure specified with the index number.
GetRectangle(Planes3D, [Index]) | Returns a Rectangle3D structure.
GetRelativeTilt(Planes3D, [Index]) | Returns the relative tilt angle of the extracted plane specified with the index number.
GetResidualsMax(Planes3D, [Index]) | Returns the maximum residual of the specified 3D plane.
GetResidualsRMS(Planes3D, [Index]) | Returns the root mean square residual of the specified 3D plane.
GetScore(Planes3D, [Index]) | Returns the score of the extracted plane with the specified index number, as a value between 0 – 100.
