A 3D scanner creates information about the scanned object in 3D. Each scanner has a predetermined format in which it can export scanned data. The Creaform device allows you to export both point clouds and STL data directly.
The type of output data is important for subsequent processing of this data in other applications.
The data is expressed using a triangular grid. The data is clearer for further editing, as the triangles form the surface of the model, creating a realistic impression of a surface model. Most CAD systems can only read STL data as graphics, some programs however, they can process this data into surfaces readable in CAD applications. STL data is used for direct printing on all 3D printers. This is the simplest representation of the shape of a 3D model.
The data is expressed using a triangular grid. The data is clearer for further editing, as the triangles form the surface of the model, creating a realistic impression of a surface model. In addition, this data also contains texture, which is made up of images captured during 3D scanning.
A point cloud defines a 3D object using captured points with X,Y,Z position. An additional value for these points can be the direction of the normal and information about the color of the point. The points are not connected in any way. Visually, it is more difficult to work with a cloud of points, as the surface is not expressed flat and the visibility of all points confuses the user. When cutting through a point cloud, only intersecting points are displayed in the cutting plane. This output format is mainly used by scanners that scan a large area around them.
We have prepared sample data for you from these professional 3D scanners:
HandySCAN 3D BLACK | Go!SCAN 3D SPARK
| Aluminum part | |
 |
Scanned aluminum part with dimensions of approx. 130x130x90 mm. The part was scanned without surface matting. The basic resolution of the polygon mesh is 0,2 mm per triangle edge. The "Smart resolution" function is used - in places with higher curvature, the resolution of the polygon mesh is automatically calculated to half the basic resolution, i.e. 0,1 mm.

| Protective case | |
 |
Scanned protective case for the peel 3D scanner with dimensions of approx. 440x360x200 mm. The trunk was scanned without matting the surface in the original black color. The basic resolution of the polygon mesh is 0,8 mm per triangle edge. "Smart resolution" function is used - in places with higher curvature, the resolution of the polygon mesh is automatically calculated to half the basic resolution. So 0,4 mm.

| Black plastic part | |
 |
Scanned plastic headlight cap with dimensions approx. 250x120x50 mm. The plastic cover was scanned without surface matting in the original black color. The basic resolution of the polygon mesh is 0,4 mm per triangle edge. The "Smart resolution HIGHT" function is used - in places with higher curvature, the resolution of the polygon mesh is automatically calculated to half or a quarter of the value of the basic resolution. So flat surfaces 0,4mm, medium details 0,2mm and smallest details 0,1mm.

| Textured work boot | |
 |
Scanned work boot including color texture. The basic resolution of the polygon mesh is 0,8 mm per triangle edge. The "Smart resolution" function is used - in places with higher curvature, the resolution of the polygon mesh is automatically halved, i.e. 0,4mm.

| Statue - Woman | |
 |
A sample scan of the statue placed in the exterior. Scanned with the Go!SCAN SPARK 3D scanner using an external battery. Scanned during daylight. About 10 position points were applied to the statue in places where the scanner was poorly oriented based on the geometry (long stretchy surface). The basic resolution of the polygon mesh is 1,5 mm per triangle edge. Smart resolution off. Scanned without texture.
