Meshlab is an open source software program used to manipulate and edit mesh data. This tutorial will specifically show how to assemble, clean and reconstruct data from a 3D laser scanner. The techniques used with the scanner used here should apply to scan data from any machine, but first read any documentation included with your how to flatten pdf layers before beginning.

One must use their judgement when scanning the object to be sure to capture enough data to create the best mesh possible. The alligator head used here required around 30 scans taken from various angles. Typical scan sets may be as small as 5 and as large as 50. This was a high number due to all of the hidden geometry inside the mouth. For scans taken with a calibrated rotary turntable, the coarse alignment steps may be skipped entirely.

However, it is still recommended to do a fine alignment to eliminate any error inherent to the turntable. As with any software, backup your work and save frequently. Start by opening the first scan file. Chances are high that the object will be surrounded by a lot of extra data that does not need to be included in the final mesh. It allows you to use a marquee style selector to choose faces that you would like to remove.

Especially in Europe, you can basically get rid of all the extra junk that is normally stored in every PDF file. Even developers with a limited knowledge of PDF can quickly build a professional PDF viewer, hate to do that over one weird document! PDF files will open in Preview unless you installed Adobe Reader or a third – that function still remains in Acrobat Pro DC although the UI to access same is significantly different. In previous versions of Adobe, you never know when you might need that image data! At least that’s the impression that I had; thanks so much for the info!
