The Line3D function has the following syntax:

Line3D(PointCloud A point cloud is a 3D structure that consists of the data points collected by a 3D vision system during acquisition.,Fixture3D,ExternalFixture,Line3D,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.

Line3D

Specifies the offsets of the 3D line to configure. It is offset from the Fixture3D origin in the following format with the following arguments:

{X0, Y0, Z0, X1, Y1, Z1}

X0 Offset of the 3D line's starting point on the X-axis from the Fixture3D origin. The value range is -inf. to inf.
Y0 Offset of the 3D line's starting point on the Y-axis from the Fixture3D origin. The value range is -inf. to inf.
Z0 Offset of the 3D line's starting point on the Z-axis from the Fixture3D origin. The value range is -inf. to inf.
X1 Offset of the 3D line's ending point on the X-axis from the Fixture3D origin. The value range is -inf. to inf.
Y1 Offset of the 3D line's ending point on the Y-axis from the Fixture3D origin. The value range is -inf. to inf.
Z1 Offset of the 3D line's ending point 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.

Returns

A Line3D data structure as the projected 3D line, or #ERR if any of the input parameters are invalid.

Results

When initially inserted into a cell, the following functions are automatically inserted into the spreadsheet to create a result table.

  X0 Y0 Z0 X1 Y1 Z1
❒Line3D GetX(Line3D, 0) GetY(Line3D, 0) GetZ(Line3D, 0) GetX(Line3D, 1) GetY(Line3D, 1) GetZ(Line3D, 1)

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

Function Description
GetX(Line3D, index) Returns the X-axis coordinate of the 3D line point specified with the index. An index value of 0 indicates the first endpoint of the line, while a value of 1 indicates its second endpoint.
GetY(Line3D, index) Returns the Y-axis coordinate of the 3D line point specified with the index. An index value of 0 indicates the first endpoint of the line, while a value of 1 indicates its second endpoint.
GetZ(Line3D, index) Returns the Z-axis coordinate of the 3D line point specified with the index. An index value of 0 indicates the first endpoint of the line, while a value of 1 indicates its second endpoint.
