VGMETROLOGY is made for metrologists. Our universal metrology solution turns your computed tomography (CT) scanner into a comprehensive and precise metrology device.
The Volume Graphics Metrology Kernel in VGMETROLOGY has been tested by the national institutes PTB (Physikalisch-Technische Bundesanstalt) and NIST (National Institute of Standards and Technology).*
* PTB and NIST verified: This software contains the Volume Graphics Metrology Kernel VGMK 2023.1.0 which passed the PTB test for “Evaluation software based on minimum-zone method for coordinate measuring machines” and the PTB test for “Evaluation software based on least-squares method for coordinate measuring machines” and which was verified by the NIST “Algorithm Testing and Evaluation Program for Coordinate Measuring Systems”. The test results were obtained under Windows (64 bit).
In contrast to tactile and optical methods, industrial CT holistically scans all surfaces of an object, even if they are inside your part or difficult to capture.
CT is the ideal basis for metrology applications. While tactile coordinate measurement methods are also non-destructive, CT is also non-intrusive. This means measuring with CT doesn’t deform the part. And unlike optical methods, CT still works accurately even if the part reflects or is translucent.
A .mvgl file contains the best possible object surface without any loss in quality.
At the same time, a .mvgl file is smaller than a .stl file with comparable precision. But unlike the .stl format, a .mvgl file is small because it only contains the surface of the object. In a .stl file, a polygon mesh approximately describes the surface of the object. The smaller the .stl file, the less accurate the mesh.
A .mvgl file contains surfaces determined with subvoxel accuracy. To achieve subvoxel accuracy, VGMETROLOGY processes the gray values of individual voxels in a way which makes even those details visible that are smaller than a voxel.*
Our .mvgl format packs everything metrologists need into one compact, easy-to-handle file. This is especially handy when exchanging metrology data sets over the Internet.
*VGMETROLOGY ES and VGMetrology VIEWER can work with subvoxel-accurate surfaces, but don’t offer surface determination.
* Optional add-on module for a fee. Supported CAD formats are: CATIA V5 (up to V5-6 R2018), Creo (up to 5.0 Beta). In beta status: CATIA V4 (up to 4.2.5), JT (up to 10.0), Pro/ENGINEER (up to 19.0), Unigraphics/NX (Unigraphics 11.0 to NX 1872), Solid Edge (V19 to V20, ST1 to ST10, 2019 to 2020), SolidWorks (97 to 2020). CAD translation technology supplied by Tech Soft 3D.
** Optional add-on module for a fee. PMI import is supported for CATIA V5 and Creo. In beta status also for Pro/ENGINEER and Unigraphics/NX. CAD translation technology supplied by Tech Soft 3D

VGMETROLOGY comes in three editions: A stand-alone edition with built-in surface determination, an essential edition VGMETROLOGY ES, which can open .vgl and .mvgl with already determined surfaces, and a viewer edition VGMETROLOGY VIEWER.
The ".mvgl" file format packs everything metrologists need into one compact, easy-to-handle file. This file contains the best possible object surface without any loss in quality.
