Scanning Coins

Note: I am having trouble attaching the files so they may show up on another message.

Here is another scan of a penny shown in a GIF file. This is about 63Kb. Rhino was used to import the xyz file and create multiple views. Then saved using Ctrl-PrtScr to copy to the clipboard. Then pasted into mspaint.exe. Then saved as a GIF file.

One of the options with my Mach3 plugin, Scan3d, is scaling for each axis. This can be used to exaggerate features. Negative scale values can be used to produce a point cloud file for a mirror image.

The Z data is exaggerated by a factor of 10. Oddly, it appears that the surface of the penny is bowl shaped.

The data is in the zipped xyz file. This is about 3Mb compressed and 12Mb uncompressed. It is plain text with space between numbers. Each line of data has x,y,z and total intensity and intensities for red, green, and blue components. The RGB components range from 0 to 255 each. The total intensity is the sum of color values and ranges from 0 to 765.

This scan was done with a Watchport/V2 camera using a 12mm f/2 lens.
