Packshot and GUI VGStudio 3.0
VGStudio offers the same excellent visualization capabilities as VGStudio MAX

VGStudio 3.0

With VGStudio 3.0, you have access to the high-tech visualization possibilities of VGStudio MAX 3.0 and its CT-reconstruction functions*. Together with the CT Reconstruction Module, VGStudio 3.0 covers the complete workflow, from the precise reconstruction of three-dimensional volume data sets using the images taken by your CT scanner to the visualization in 3D and 2D as well as impressive animation.

Voxels, or the 3D-equivalent of pixels, form the basis of the volume data sets that VGStudio 3.0 reconstructs from CT scans. Each voxel represents a specific area of the object, while their gray values provide information about the material found there. With VGStudio 3.0, you can classify and color-code volume data based on its gray values.

In order to display the interior of an object, VGStudio 3.0 can 'cut' the 3D model in any desired direction. Furthermore, some basic measurement features are available for quickly quantifying distances, angles, etc.

*The CT Reconstruction Module is not part of the basic version of VGStudio 3.0 and must be purchased separately.

New in VGStudio 3.0

Just as with VGStudio MAX 3.0, VGStudio 3.0 has been completely redeveloped to take full advantage of the capabilities of modern hardware. Other new features in version 3.0 include:

  • Open metrology projects created with VGMetrology or VGMetrology ES (.mvgl files) in VGStudio 3.0 or myVGL 3.0.
  • Open and save the new single-files that combine all files, folders, and even the source data (.vgarchive files).
  • Open data sets with unloaded gray values.
  • Publish .pdf files directly without third-party tools.
  • Make use of the tremendously improved CT reconstruction functions that were introduced with VGStudio MAX 3.0.
  • Choose from two interface themes: the familiar ‘bright’ theme and a new ‘dark’ theme, which is perfect for working with gray value images.
  • Use the new export and reporting features that you already know from VGStudio MAX 3.0: top-level reporting, VG Report Format (.vgrf), and customizable test reports.

Basic Functionality


VGStudio 3.0 displays volume data in 3D and in 2D slice images. You can visualize any number of volume data sets simultaneously. The possibilities are limited solely by the hardware being used.

You can choose from a range of different rendering methods for 3D representation: Ray tracing, Isosurface, MIP, X-ray, and others. Different types of light sources are also available and can be combined as required. Depending on the rendering method, realistic shadows can also be generated in the 3D view.

You can go one step further with stereo viewing: Use any renderer to generate image pairs that create the illusion of seeing an object in 3D. Stereo viewing requires either special glasses or dedicated displays.

It’s also possible to scroll through the dataset along any desired axis.

Working with Bent Structures

VGStudio 3.0 simplifies the viewing of bent structures such as conductor paths.

The non-planar viewing mode enables you to ‘unroll’ cylindrical objects or to flatten/level a dented surface and then scroll into the object slice by slice. What had hitherto only worked with cylindrical objects now also works with freeform surfaces.

The thick slab option combines consecutive slices into a single 2D view, making the information in these slices visible at a glance.

Clipping and Positioning of Objects

'Clipping' allows you to make virtual cuts into a volume object in the 3D display area.

Clipping tools are available as planes or boxes. Different degrees of transparency can be applied to clipped areas in order to gain a better understanding of your part.

Objects can be freely positioned and rotated within the 2D and 3D display areas. Alternatively, it is also possible to precisely position your data set within a coordinate system either through intelligent automatic alignment or by entering the parameters manually. This applies not only to the volume data, but also to all other objects such as light sources and clipping tools.

Data Import/Export

VGStudio 3.0 allows volume data to be imported in most commonly used formats. Any number of data sets may be loaded into the application at the same time. To save memory, you can open data sets with unloaded gray values.

VGStudio 3.0 opens and saves files in the .vgl format (used by VGStudio and VGStudio MAX) and.mvgl files (used by the metrology software VGMetrology).

If an object has been scanned in sections, VGStudio 3.0 can assemble and export these sections in a single data set.

CAD models may be imported as a .stl file.

The 'Pack and go' feature makes sharing and archiving projects easy. It packs together all project-relevant data and can compress the file if desired. A single-file option in VGStudio 3.0 combines all files and folders – including the source data – into a single file. This file is saved in the new .vgarchive format.

Object Management

VGStudio 3.0 treats all elements, such as volume data and light sources, as 'objects'.

These objects are displayed in a hierarchical directory called the ‘scene tree’ and can be grouped, copied, cut, and inserted as required.


Use bookmarks, e.g., to present a CT data set to your colleagues and customers in an organized way. Bookmarks allow you to easily switch between different project views.

Data Analysis and Measuring Functionality

VGStudio 3.0 offers a range of basic measuring features. With these easy-to-use measuring tools, you can measure distances, angles or polylines within 2D slice images.


With VGStudio 3.0, you can bring your 3D objects to life with impressive animations. These animations may contain any number of objects and include flights around the object or through the object.

The 2D display may also be used to create film sequences in which the image scrolls through the image stacks.

You can save animations directly as a .avi or .wmv file, or you can create image stacks for professional post-processing.

When saving slice images or movies, the new Picture-in-Picture option shows you the exact position of the respective slice within the 3D model.

Documentation of Results

VGStudio 3.0 provides numerous features for presenting data and exporting results:

  • Copy images to other applications, save them in standard image formats or create animations.
  • Publish .pdf files directly without third-party tools.
  • Use the new export and reporting features that you already know from VGStudio MAX 3.0:

    • Top-level reporting to generate reports on all the analyses linked to an object
    • The new VG Report Format (.vgrf) to save analysis results in a standardized folder and file structure
    • Completely customizable test reports that you create together with Microsoft Excel (function requires Microsoft Excel)
