Geometry analyses to qualify even the most complex outer and inner geometries: the add-on modules for geometry analyses offered by Volume Graphics.
The Volume Graphics Metrology Kernel in VGSTUDIO MAX 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 3.2.0 140356 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).
Easily apply a conventional measurement plan to your voxel data.
The metrology capabilities of Volume Graphics software are verified by the Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute. PTB 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 VGSTUDIO MAX and VGMETROLOGY.
The accuracy of the evaluation software (Volume Graphics Metrology Kernel, version VGMK 3.2.0 140356) was verified by comparing the results obtained from the software with reference results provided by the PTB for the same set of data.
For Chebyshev, PTB tested the basic features (called "geometry elements" in Volume Graphics software) straight line 2D, plane, circle 2D, sphere, and cylinder and for Gauss, the basic features straight line, plane, circle, cylinder, sphere, and cone.
PTB’s maximum permissible errors (MPE) for deviations from the reference values for all quality characteristics are 0.1 μm (0.0001 mm) and 0.1 μrad. Volume Graphics’ algorithms for computing “Chebyshev associated features” and for computing “Gaussian associated features” delivered even better results in the PTB test.
The algorithms tested by PTB are used in VGSTUDIO MAX (Windows 64 bit) and VGMETROLOGY (Windows 64 bit).
Between material and air is the surface. Often the surface is defined by a single gray value. When using Advanced Surface Determination, however, the gray values are processed depending on the gray values of the surrounding voxels. The result is a much more accurate surface.
Not just smoother but also more accurate: Using the subvoxel-accurate surface determination (right) reduces your measurement uncertainty by giving you details the voxel-based surface determination (left) is not able to show.
