This chapter describes Artec Studio settings that you can change through the Settings dialog. To display this dialog, select Settings... from the File menu or hit the F10 key.

The user-adjustable settings are divided into categories under separate tabs. These categories include the following:

  • General
  • Performance
  • Scan
  • UI
  • Miscellaneous


The General tab contains basic Artec Studio settings and includes the following options (see Figure 148):

  • Project-storage folder
  • Autosave options
  • Import/export options
  • Default import units and Default export units
  • View control settings

Figure 148 General settings page.

Project-Storage Path

You can set the default folder in which Artec Studio will save projects by typing in the path, or select it from the dialog by clicking Browse....

Autosave Options

When the Save project before starting algorithms option is enabled, the application will always save your project before running any processing routines. The Restore loading state of scans after algorithms finish checkbox allows you to control loading of selected scans once the algorithm is complete. Artec Studio always loads selected scans into memory before launching an algorithm; if a scan is not loaded at this point, the application will automatically save it to the hard drive after the algorithm finishes, freeing up memory. For more information about autosaving projects, see Autosaving a Project.

Registering Artec Studio as Default Viewer

Artec Studio supports various file formats. To make it the default application for supported formats, click Change... and select the formats you want the application to open by default (see Figure 149):

—project files for Artec Studio
—single-scan export/import format
—format for saving polygonal models obtained using 3D scanners
—3D-model export format for fast-prototyping equipment
—virtual-reality files in VRML 1.0 and VRML 2.0 format
—texturized 3D models; Wavefront OBJ format

Figure 149 Making Artec Studio the default application for various file types.

For more information on importing and exporting files, see Exporting Models and Scans and Importing Models and Scans.

Opening Files

Artec Studio can serve as the default viewer for SPROJ, SCAN, PLY, STL, OBJ and VRML (*.wrm) formats. To open each subsequent file in a new application window, select Open new model in a new window. If the Open new model in the same window option is selected, Artec Studio will use existing windows to display subsequent files.

Surface-Consistency Detection During Import

The Surface-consistency detection during import option instructs Artec Studio to examine imported files for defects. Select one of the following parameters:

Do not detect
—disable automatic surface-consistency detection
Detect & ask
—enable automatic surface-consistency detection; Artec Studio will prompt you to start defect correction
Always detect & fix
—enable automatic surface-consistency detection and correction

Model Placement

When exporting, the application can automatically center scans and models on the origin of the axis grid. To enable this option, select the Move model to origin of the axis grid during export checkbox. If the checkbox is cleared, the application will save the model’s current placement on the axis grid when exporting surfaces.


In Artec Studio, all software operations use millimeters as the default measurement unit. If you need to import or export a model in other units, change the settings under Units. The software applies these settings only when importing or exporting a model.

Selecting the Show unit-selection dialog on import option enables you to choose on import which measurement unit was used to create the scan (see Figure 150). Artec Studio supports units of millimeters, centimeters, inches and meters. If in most cases you import data in a particular measurement unit, but you might occasionally import models created using another unit, you should enable the Only if object is less than __ mm option and enter the threshold value. In this case, the unit-selection dialog will only appear if the model dimensions are below the threshold value.

The Default import units and Default export units dropdown lists determine the default measurement units for importing and exporting models.


Figure 150 Unit-selection window.

View-Control Settings

Artec Studio allows you to use Scroll wheel to zoom in on the model in the 3D View window. You can take advantage of this capability in two ways:

Clear the Mouse-wheel zoom to cursor checkbox
to enable zooming to the center of the screen. In this case, you must keep the target area in the screen center and readjust its position from time to time.
Select the Mouse-wheel zoom to cursor checkbox
to enable interactive zooming to the mouse-cursor position. In this mode, you need only keep the cursor on the target area while spinning Scroll wheel forward and backward.


The following parameters are user adjustable by way of the Performance tab (see Figure 151): multithreading, memory usage, command-history storage, compression levels for stored data, texture-recording mode and Real-time fusion settings.


Figure 151 Performance-tab options.


On computers that feature multicore processors, Artec Studio uses all cores by default. If you would like to limit the number of cores the application employs, clear the Use all available processor cores checkbox and enter the number of concurrent threads manually.


Under Memory, the Settings dialog shows RAM availability. If the current amount is insufficient, you can try to increase it by clicking the Compact memory button. Artec Studio will clear the command history and attempt to optimize memory allocation. Clicking Compact memory won’t permanently delete the history, but simply unload it from memory. The Undo command will reload it. For more information about saving projects, see History of Project Changes.


You cannot unload the command history from memory if you haven’t saved the project. Save the project and try again.

Artec Studio automatically optimizes memory allocation after each algorithm finishes. This function is handled by the Compact memory after algorithm completes checkbox. In contrast to the button, it doesn’t unload command history.

Command History

Under the Command history section you can limit the amount of history Artec Studio will save. By default, the maximum values are set as a certain number of commands and size on disk (in MB). If necessary, you can clear the Max history length checkbox. Doing so means the program will save all history for each project from the beginning. You can clear the project history by clicking the Clear command history button; the application will prompt you to confirm this action.


Once you clear the history, you cannot return to an earlier project version.

Data-Compression Level

The Data-compression level slider allows you to change the amount of file compression when saving data. Higher compression saves disk space, but loading and saving these scans takes longer. When attempting to save projects that allocates more than 6 GB of memory, the dialog will appear prompting you to use maximum compression.


Maximum compression settings are optimized to ensure that the shape of your models and frames will be preserved. Insignificant deformation may, however, occur. Change the slider position as necessary.

Table 14 File compression in Artec Studio.
Slider Position Type Compatibility Output File Size
Left No compression All versions Large
Middle Medium compression (lossless) All versions Medium
Right Maximum compression (lossy) Artec Studio 12 and later Small

Texture-Recording Mode

By default (Automatic texture recording enabled), Artec Studio doesn’t capture texture for every frame. You can, however, manually specify the frequency for capturing texture frames by using the Record texture every __th frame spinner.


Figure 152 Spinner for adjusting capture frequency of texture frames.

Real-Time Fusion Settings

Real-time fusion offers two optional settings (see Scanning With Real-Time Fusion):

Voxel size (mm)
The fusion resolution. It affects the algorithm’s performance and quality. The lower the value, the sharper the shape of the model. Note that specifying low values may produce noisy surfaces.
Buffer size

Amount of GPU memory employed to reconstruct a Real-time fusion object in the scene. The default value depends on the computer’s available GPU memory. Note that Artec Studio may fail to correctly determine the upper limit if your computer has an Intel HD Graphics card. The more memory you have, the larger the scene you can scan in Real-time fusion mode. The slider doesn’t define the total finite memory size, however; the algorithm employs system memory (RAM) when GPU memory is consumed.


Avoid altering the Buffer size unless you have started noticing artefacts while scanning.

Table 15 Default values of Voxel size.
  Artec EVA Artec Spider Third-Party 3D Sensors
Voxel size (mm) 1 0.3 3


The Scan tab allows you to edit the parameters that the application uses both while scanning and while postprocessing the results (see Figure 153).


Figure 153 Scan-settings tab.

Algorithm Settings

Artec Studio automatically selects and displays settings for each scanner type in the Current scanner type dropdown. If it fails to correctly identify your scanner type, select the appropriate scanner manually. While using the application, you may need to change algorithm settings manually. To reset all settings to their default values, click Reset to defaults.

Current user preset allows you to save the current parameter values in the Tools panel. By selecting a saved preset, you can change all settings at once. Note that this option applies only to the selected device type.

Photogrammetry Settings

Photogrammetry settings allow you to define the target size. Inner target diameter (mm) corresponds to the diameter of the white circle in the middle of the target; Outer target diameter (mm) corresponds to the outer diameter of the target’s black ring. The most popular targets have diameters of 6 mm and 12 mm; the values 5 mm and 10 mm correspond to the Scan Reference target. See Target-Assisted Scanning for details.

The Disable hybrid tracking for .obc checkbox ensures that tracking is purely based on targets. Select the checkbox if you don’t want the texture and geometry features to assist target scanning (Using Photogrammetry Solution (Scan Reference)).


The Capture section covers settings related to the trigger button for the Artec MHT scanner, as well as the scanning-depth range and individual frames acquired during the scan.

The first option is the Trigger mode for device button checkbox, which changes the button behavior on the Artec MH and Artec MHT scanners. For details regarding these buttons, see Scanner Buttons and Capture Modes.

The scanner has a defined depth range. If it’s too close to the object, it may fail to capture all or part of the object. On the other hand, if the scanner is too far away, various types of 3D “noise” will appear in the scene, complicating the postprocessing effort and affecting the final results. Therefore, you should position the scanner as close as possible to the object without crossing the cutoff plane. Default settings for each 3D scanner contain minimum and maximum limits within which you can position the cutoff planes. The scanner model determines these values. If you are using an Artec L scanner or 3D-sensor and high accuracy is of lesser importance, however, you can adjust the depth boundaries manually, allowing you to scan closer to or further from the object than the recommended distances indicate. To this end, mark the Override default depth range checkbox and enter new range values.


Redefining the depth range may reduce accuracy.

Scan Using Auto-Alignment

The Scan using auto-alignment option is enabled by default and is covered in the Resuming Scan After Lost Tracking and Auto-align new scans with those marked in Workspace sections. The application’s behavior varies depending on this option’s value, as Table 16 shows.

Table 16 Application behavior with option enabled and disabled.
Scan Using Auto-Alignment On Off
Tracking Mode Geometry + Texture Geometry or Geometry + Texture
Audio Notification? Yes (see Audio Notification) Yes
Message in 3D View Searching for position: Point 3D Scanner at the object to continue Tracking lost: Repeat scan using slower motions or additional features
Instructions Direct the scanner at any already captured region with sufficient texture, maintaining the original scanner orientation relative to the object Direct the scanner at the last captured region
Data Recording Handled in a newly created scan Handled in the same scan

Misalignment Detection

In some cases, Artec Studio may incorrectly determine relative frame positions, resulting in misalignment. When this error occurs, you must restart the scanning session and remove the misaligned scans. Alternatively, you can attempt to fix the misalignment by breaking the scan into several segments. Further information about addressing this problem by dividing scans is available in Separating Scans. To prevent possible misalignment and improve your scanning experience, Artec Studio features a Misalignment detection for EVA scanner setting that functions during the scanning process. However, if you have difficulty maintaining the tracking when scanning particular objects, you can disable this setting.

Options are as follows:

On (Hybrid tracking only)
—default value, option works for Geometry + Texture tracking mode
—option works for all tracking modes, including Geometry
—option is turned off for all trackers.

Default Capture Settings

Artec Studio allows you to change the characteristics of single-frame surfaces as the scanner captures them. To change the default parameters, clear the Use default capture settings checkbox and change the settings manually in the displayed window. The options below are user adjustable:


We recommend using default settings. Poorly chosen settings may reduce data quality.

Triangles step
—point density for a frame mesh
Minimum object size
—smallest object scanned, by number of polygons
Length filter threshold
—triangle-filtration threshold by edge length (maximum possible size in mm)
—use interpolation for parts of surface that are missing data
Max interpolated length
—maximum size of areas to be interpolated (in mm)
Max angle
—triangle-filtration threshold by maximum angle (in degrees) between the triangle’s normal and the camera’s sight vector
Geometry registration threshold
—the higher the threshold, the stricter the quality requirements for the geometry being scanned. Therefore, determining the proper geometry in the scene is more difficult in such cases. Subsequently, Artec Studio runs geometry registration less frequently, making way for texture registration. Works with Geometry + Texture tracking only, values are between 0 and 1.


The UI page allows you to edit user-interface settings (see Figure 154) and covers the following categories:

  • Audio notification
  • Workspace colors
  • Warnings
  • Surfaces that Artec Studio displays during a scan

Figure 154 Interface-settings tab.

Audio Notification

Sometimes, automatic alignment in real time is impossible during the scanning process, and the program is unable to align the previous frame with the current one (see Resuming Scan After Lost Tracking). When this situation occurs, Artec Studio issues an audio warning that stops once you reposition the scanner and the software again finds its location in 3D. To enable or disable this feature, use the Enable audio warnings in scan mode checkbox. A standard “beep-sound” is the application’s default sound. You can choose any WAV file as the warning sound. To this end, click the ... and specify a file path.


You will only receive audio warnings during a scan if your computer is equipped with a sound card and speakers.

Workspace Colors

Artec Studio automatically chooses display colors for newly created scans. You can select any of the standard palettes:

  • Full palette
  • Light colors
  • Web-safe colors
  • Random colors
  • Monochrome


The Warnings options allow you to toggle certain notifications. They include the following:

Warn on exit if project has unsaved changes.
If this option is enabled, Artec Studio will warn you that you will lose unsaved data if you close the application without saving your work.
Show OpenGL compatibility issues on startup.
Artec Studio requires OpenGL version 2.0 and some OpenGL extensions to function properly; your PC may or may not currently support these capabilities. Selecting this option activates a display window on startup containing information regarding possible missing extensions.
Texture-healing brush: warn if over __ polygons selected.
This checkbox instructs the application to display a warning if you exceed the maximum number of polygons to be inpainted at one time. This limit reduces the potential for the computer to hang up. Specify a suitable value for your system, or clear this checkbox if you require no warnings of this kind.

Displaying in 3D View Window

You can change the way you see surfaces and points during the scanning process, adjust their colors as well as the background color, and specify the mode for frame playback. To these ends, use the settings below:


Last scanned surfaces
—number of visible surfaces most recently captured that will appear in 3D View during scan
Visible surfaces
—total number of visible surfaces displayed during scan (equal to the number of most recently scanned surfaces plus the number of key frames to display)
Simple rendering mode threshold
—maximum number of polygons in the viewport beyond which Artec Studio will switch to simple rendering mode during 3D navigation
Point size
—number of pixels for rendering each point when using the Points or the Points and solid rendering mode


—color of last scanned surfaces
—color of correctly aligned surfaces
—color of surfaces in preview mode
—color of unaligned (and thus dropped) surfaces
Key frames
—color of key frames (surfaces)

Usage Information

You can help us improve the quality and performance of Artec Studio by allowing us to collect and send usage information to Artec Group. This information will not be used to identify you, and it excludes your project data, 3D surfaces, textures and any other data that you obtain and process using Artec Studio. By default, the Collect and send anonymous usage data to Artec checkbox is selected. We recommend leaving this checkbox marked so we can better improve the application.

When installing Artec Studio, you can decide whether you want it to collect and send usage data. The same checkbox described above also appears in the final installation dialog (see Figure 33).


Figure 156 Miscellaneous-settings tab.
