Line3D

The Line3D function allows you to create a fixtured 3D line segment in the point cloud.

It returns a Line3D structure containing the settings of the fixtured 3D line segment.

Line3D Inputs

The Line3D function has the following syntax:

Line3D(PointCloud,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 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) about the PointCloud Z-axis. The value range is -360 to 360. External references with values outside the allowed range will be normalized 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 will result in an error.
Tilt Direction Specifies the direction of tilt (in degrees) from the tool's rotated PointCloud X-axis, about the tool's PointCloud Z-axis. The value range is -360 - 360. External references with values outside the allowed range will be normalized to the allowed range.
Note: This parameter is available only if External Fixture is set to 0.
External Fixture

Specifies a reference to a Fixture3D structure defined in another cell to be used as the function's fixture. Set to 0 (OFF) to use the function's internal fixture 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.

Line3D Outputs

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.

Line3D Data Access Functions

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.
