Mesh Pop-Up Menu

The following options are available to modify and transform meshes.

Apply Transformation From

Applies transformations, such as translations, rotations, and scaling, that were applied to a reference object to the selected data (see Applying Transformations from Other Objects).

The following options are available to align meshes.

Centroid With

Automatically aligns the centroid of the selected mesh with the centroid of another object. Applicable objects include volumetric image data, regions of interest, multi-ROIs, and other meshes.

Reference objects can be selected in the Choose the Object to Align With dialog, which is shown below.

The following options are available for creating new box shapes from meshes (see Adding and Editing Shapes).

Current Bounding Box… Automatically creates a box that corresponds to the dimensions of the selected mesh. If required, you can edit the geometry of the box.

Current Clip Box… Automatically creates a box that corresponds to the dimensions of the selected mesh's clip box. If required, you can edit the geometry of the box.

The following options are available for exporting meshes.

Export Mesh to File

Lets you save meshes in a number of different file formats suitable for 3D printing and other purposes (see Exporting Meshes).

Export as ORSObject

Exports meshes in the ORS Object (*.ORSObject extension) file format (see Exporting Objects).

ORS files are proprietary binary formatted files in which data is written sequentially and XML (Extensible Markup Language) is appended after the binary data. Scalar information contained in the file will be conserved whenever meshes are exported in this format.

Opens the Measurement Inspector panel (see Evaluating Meshes with the Measurement Inspector).

Provides a shortcut for selecting macros that can be executed for a mesh (see Recording and Playing Macros).

Opens the User Data dialog, in which you can view detailed object descriptions, as well as add fields to further describe the selected objects (see User Data).

Opens the Mesh Decimator panel, in which you can reduce the number of vertices, edges, and triangles in a mesh (see Decimating Meshes).

Opens the Mesh Smoothing panel, in which you can smooth meshes with a selected method and number of iterations (see Smoothing Meshes).

Opens the Mesh Subdivider panel, in which you can increase the resolution of the selected mesh by dividing its triangles into smaller units (see Subdividing Meshes).

Opens the Mesh Registration panel, in which you can register a selected mesh with a reference (see Registering Meshes).

Calculates the deviation (distance) between two sets of meshes and shows the error as a colored map on the mesh surfaces (see Generating Deviation Maps).

Calculates the deviation (distance) between two sets of meshes and shows the error as a colored map on the mesh surfaces (see Generating Deviation Maps).

Lets you compute the number of non-manifold edges in a selected mesh. This function can be used to verify that a mesh does not contain any edges with more than two faces attached to it. You can use this option to evaluate the integrity of a mesh that will be used for 3D printing.

As shown in the example below, non-manifold topology polygons have a configuration that cannot be unfolded into a continuous flat piece. This condition, in which more than two faces share an edge, is known as multiply connected geometry.

How to Compute a Non Manifold Edges Count

1. Right-click the mesh you need to analyze and then choose Get Non Manifold Edges Count in the pop-up menu.

   The results are computed automatically and appear in the Mesh Information dialog, shown below.

   

   You should note that a value of 0 indicates that the mesh does not contain any non real-world geometry.

Lets you delete selected measurements from scalar meshes (see Deleting Scalar Values from Meshes).

Lets you export selected measurements from scalar meshes to a comma-separated values (*.CSV extension) file (see Exporting Scalar Values from Meshes).

Lets you import scalar values contained in a selected comma-separated values (*.CSV extension) file to the selected mesh (see Importing Scalar Values from CSV Files to Meshes).

Lets you map the scalar values from another object, such as an image, multi-ROI, or scalar mesh, to the selected mesh (see Mapping Scalar Values to Meshes).

Lets you copy selected measurements contained within a scalar mesh to the selected mesh (see Copying Scalar Values to Meshes).

Lets you add a constant vertex measurement to the selected mesh. The name of the measurement and its value can be entered in the Name and Value dialogs, respectively.

Lets you automatically align the axis of inertia of the selected mesh with the axis of inertia of another mesh.

Automatically computes and adds normal angles from the Z-axis.

Lets you apply linear transformations to the selected scalar value(s) by modifying the slope and/or offset values.

Automatically computes and adds scalar values of curvature calculated with the Gaussian method.

Automatically computes and adds scalar values of curvature calculated with the Mean method.

Automatically computes and adds scalar values of distances calculated from the mean position of a series of points.

Copies the selected mesh. Copied meshes will appear as new items in the Data Properties and Settings panel.

Lets you assign a new unit to scalar values. In this case, the default unit of the stored scalar values will be changed, but the scalar values will be kept as is. For example, if the scalar value stored is 0.75 meters and the unit assigned to length is centimeters, then the scalar value shown would be equivalent to 0.0075 meters. You should note that the default units of lengths, areas, and volumes is meters, while the default unit of angles is radians. Discrete and continuous values are not stored with units.

The following example illustrates how assigning a unit to scalar values is implemented. You should note that measurements will always appear in the units selected for the scene views.

How to Assign a Unit to Scalar Values

1. Right-click the scalar mesh and then choose Assign Unit to Scalar Values in the pop-up menu.

   The Choose a Scalar Values Slot dialog appears.

   

2. Choose the scalar value slot that you want to assign a unit to in the Slot drop-down menu and then click OK.

   The Choose Unit Type dialog appears.

3. Choose a unit type in the Choose Unit Type dialog, as shown below.

   

4. Click OK.
5. Choose a unit in the Choose Unit dialog, as shown below.

   

   This is the unit that will be applied to the stored scalar value.

6. Click OK.

   The selected scalar value slot is updated.

Extracts the object's history as a macro, which can provide an audit trail to help troubleshoot processing issues (see Extracting Object Histories).

Note Object history macros can also be edited and replayed to create new objects.

The following options are available for exporting meshes.

Export as Multiple ORSObjects… Exports each selected item as a separate file in the ORS Object file format (*.ORSObject extension) to a selected folder (see Exporting Objects). You should note that if the selected objects share the same name, their file names will be appended with a sequential number.

Export as ORSObject… Exports all selected items in a single file in the ORS Object (*.ORSObject extension) file format (see Exporting Objects).

Provides a shortcut for selecting macros that can be executed for the number of items selected (see Recording and Playing Macros).
