The Secret to Perfect 3D Scans of Difficult Surfaces

The Secret to Perfect 3D Scans of Difficult Surfaces

Certain objects that you scan may have issues being scanned, including clear and shiny objects, or certain black colors such as carbon fiber. This is due to the capture camera failing to identify faces (in the case of clear objects) or reflects; making the scan noisy for shiny or black objects. 

To correct this common 3D scanner issue, the object needs a coating to add opaqueness to cover the difficult areas to scan. Tape can be used in a pinch, but you may compromise the geometry of the object.

How to Balance Quality With Speed and File Size for Artec and Creaform 3D Scanners

How to Balance Quality With Speed and File Size for Artec and Creaform 3D Scanners

Handheld scanners convert millions of points of data to millions of polygons – taking up computer resources and disk space. If you work with 3D scanners, you already know that file size and processing data are the biggest limits of the technology.

By understanding how different scanners capture and process data, we can find ways to work around these limitations and optimize our scanning and processing times. This can be done in the raw data or final mesh depending on the end-goal of the project. Some software for example will let you combine different mesh and point cloud data together to increase accuracy and resolution. Others you can edit the mesh itself to show two different resolutions, increasing the polygon count in areas of interested while decreasing on simpler surfaces.

How to Fill Holes Using Bridges in Artec Studio

How to Fill Holes Using Bridges in Artec Studio

Hole-filling has always been present in Artec Studio, but new in Studio 14 is the Bridge option within the Fix Holes menu. This tool allows Artec 3D scanner users to constrain how holes are filled for more controlled results.

Hybrid Modeling With Geomagic Design X

Hybrid Modeling With Geomagic Design X

Most CAD users are familiar with the relative difficulty of modeling organic shapes and complex curvature using traditional CAD tools. While some CAD programs and reverse engineering programs have automated surfacing techniques to better deal with these geometries, they are not conducive to downstream editing. They also typically do not create perfectly prismatic features like true planar faces and cylinders. Because they are based on splines, they also have trouble defining sharp corners. This makes them often unsuitable for expressing mating surfaces, areas with mechanical function, and other key features that require perfect definition.
