# Sphere3D

The Sphere3D function Functions are tools that are available in Spreadsheet for processing and analyzing acquisitions or other results. You can add functions to your Spreadsheet job to create tool chains and produce results for specific applications. allows you to create a fixtured 3D sphere in the point cloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition.. It returns a Sphere3D structure containing the settings of the fixtured sphere.

Inputs

The Sphere3D function has the following syntax:

Sphere3D(PointCloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition.,Fixture3D,ExternalFixture,Sphere3D,Show)

Parameter | Description
PointCloud | Reference to a cell containing a point cloud. The default value is $A$0.
Fixture3D | Specifies the point cloud coordinate system in which the 3D fixture A fixture is a coordinate location on the image that keeps the tool in the place determined by the fixture. is defined. It is offset from the PointCloud origin in the following format with the following arguments: {X, Y, Z, Rotation, Tilt, TiltDirection}
X | Offset on the X-axis from the PointCloud origin.
Y | Offset on the Y-axis from the PointCloud origin.
Z | Offset on the Z-axis from the PointCloud origin.
Rotation | Specifies the in-plane rotation in degrees around the PointCloud Z-axis. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.
Tilt | Specifies the tilt angle in degrees from the PointCloud Z-axis after rotation. The value range is 0-180. External references with values outside the allowed range result in an error.
Tilt Direction | Specifies the direction of tilt in degrees from the rotated PointCloud X-axis of the tool, around the PointCloud Z-axis of the tool. The value range is -180 to 180. The tool normalizes external references with values outside the allowed range to the allowed range.
Note: The Fixture3D parameter is only available if you set External Fixture to 0. Note: You can use the Fixture3D parameter to set the ROI fixture.
External Fixture | Specifies a reference to a Fixture3D structure defined in another cell. The function uses the referenced cell as the fixture of the function. Set to 0 (OFF) to use the internal fixture of the function instead.
Sphere3D | Specifies the radius and location of the 3D sphere. It is offset from the Fixture3D origin in the following format with the following arguments: {Radius, X, Y, Z}
Radius | The radius of the 3D sphere. The value range is 0.001 to inf.
X | Offset of the center point of the 3D sphere on the X-axis from the Fixture3D origin. The value range is -inf. to inf.
Y | Offset of the center point of the 3D sphere on the Y-axis from the Fixture3D origin. The value range is -inf. to inf.
Z | Offset of the center point of the 3D sphere on the Z-axis from the Fixture3D origin. The value range is -inf. to inf.
Show | Selects the type of graphics to overlay on the image.
0 = hide all (default) | All graphics will be hidden, except when the cell containing the function is highlighted in the spreadsheet.
2 = input graphics only | The input data will be displayed at all times.

Outputs

Returns | A Sphere3D structure containing the parameters of the configured sphere, or #ERR if any parameter has been configured incorrectly.
Results | When initially inserted into a cell, the following functions are automatically inserted into the spreadsheet to create a result table.
| Radius | X | Y | Z
❒Sphere3D | GetRadius(Sphere3D) | GetX(Sphere3D) | GetY(Sphere3D) | GetZ(Sphere3D)

Vision Data Access functions

The following Structures 3D Vision Data Access functions are automatically inserted into the spreadsheet to create the result table:

Function | Description
GetRadius(Sphere3D) | Returns the radius of the sphere.
GetX(Sphere3D) | Returns the X-axis coordinate of the sphere's center point.
GetY(Sphere3D) | Returns the Y-axis coordinate of the sphere's center point.
GetZ(Sphere3D) | Returns the Z-axis coordinate of the sphere's center point.
