ScanStudio performs 4X oversampling on your data. The result: higher quality, less noise.
ScanStudio also lets you control how your scan data is processed to create your finished 3D surfaces.
You can set parameters that define how much mathematical filtering is applied to smooth your surfaces, as well as setting how much decimation is done to reduce the complexity and size of your model.
Why decimate? Why not just use every datapoint all the time? Since your scanner can collect literally millions of points in minutes, the goal is generally to produce the smallest model file that sufficiently represents the interesting details. Smaller files transmit faster and render faster as well.
ScanStudio's intelligent variable decimator allows you to specify a resolution tolerance for the end result which intelligently combines triangles to shrink the dataset size while still preserving detail.
