Point3D

The Point3D function allows you to create a fixtured 3D point in the point cloud. It returns a Point3D structure containing the settings of the fixtured 3D point.

The Point3D function has the following syntax:

Plane3D(PointCloud,Fixture3D,ExternalFixture,Point3D,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 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.
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.

Point3D

Specifies the offset of the 3D point to use. It is offset from the Fixture3D origin in the following format with the following arguments:

{X, Y, Z}

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.
Note: This parameter is available only if External Point is set to 0.
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 Point3D data structure containing the constructed 3D point, 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.

  X Y Z
❒Point3D GetX(Point3D) GetY(Point3D) GetZ(Point3D)

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

Function Description
GetX(Point3D) Returns the X-axis coordinate of the 3D point.
GetY(Point3D) Returns the Y-axis coordinate of the 3D point.
GetZ(Point3D) Returns the Z-axis coordinate of the 3D point.
