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 (Windows 64 bit) has been verified by the Physikalisch- Technische Bundesanstalt (PTB).*
* PTB (Germany’s national metrology institute) tested the algorithms based on the minimum-zone method (“Chebyshev”) and on the least-squares method (“Gauss”). These algorithms are used for coordinate measurement in VGMETROLOGY.
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-precise 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 (V11.0 to NX 12.0), Solid Edge (V19 – 20, ST – ST10), SolidWorks (97 up to 2018).
