2 very useful features, Optimize Surface and Optimize Model, have been included since the release of VXscan, several years ago. Even if these are still part of VXelements, they are actually not been used, or they are underused because people don’t know them or think that they are time-consuming.
It is worth noting that these 2 iterative features can be interrupted during calculation, while retaining the improvements made. Therefore, there is no reason not to use them, but in order to maximize results, it is better to let calculations run until the end. Indeed, these features use very powerful algorithms working with the sensors’ raw data. So it would not be possible to achieve such results with post-treatment software.
More specifically, the Optimize Model feature is available with sensors from the Handyscan 3D family of products. VXelements analyzes distribution errors in the model and redistributes it to minimize the impact of local deviation, in order to achieve a more precise target model. In order to save calculation time, users need to first acquire targets, then optimize, before acquiring the surface. The Optimize Model feature is strongly recommended for all parts and application types.
To save calculation time, optimize the model before acquiring the surface (scan in positioning feature mode).
As for the Optimize Surface feature, it is available with sensors from both the Handyscan 3D and MetraSCAN 3D families of products. VXelements will then analyze the noise on the surface and reduce its impact, in order to generate a better-quality STL surface. Noise can come from several factors such as an inadequate surface finish, incorrect sensor positioning, or unstable reference model. This feature works especially well when laser crosses are present on the surface.
Here is an example of how powerful this feature is, taken from a reverse engineering scan on which the sensor was not positioned correctly, and this, several times. You can easily see how the optimized surface eliminated many laser crosses visible on the initial surface.

After optimization
In short, these 2 features make it possible to diminish the user-related impact on the quality of results. By working at the source, these features can deliver better surfaces in terms of both quality and accuracy.
