3D Projectile Point from the Texas Forestry Museum

As many of you know, we recently purchased a new 3D scanner that will allow us to scan small objects. This is a very busy week as we are documenting the projectile points in the Texas Forestry Museum; however, I wanted to give you a taste of things to come.

This piece was made from silicified (petrified) wood by a very talented maker.

  1. Nice job on getting the edges clean – we know from experience that can be really difficult on chipped lithics. Great texture reproduction too. A viewer with pause and zoom would be nice!


    1. Usually we don’t include a scale with 3D models because you can actually take measurements on the model itself. I’ll look into it, but I don’t know (yet) how to include one in the animations.


    1. Hi Cliff – we’re using a NextEngineHD to scan the points (2 scans – 10 divisions), and all of the post-processing happens in Geomagic DesignX. Also, before the scan, we’re (liberally) applying talc/baby powder to each of the projectile points to cut down on reflectivity – helps out a lot.


      1. Thank you for passing on the info. I have a next engine scanner. I’ll replicate your method and see if I can get it to work. I’ve tried a bunch of ideas without so much luck. I’ll come back with the results. Cliff


      2. Sounds good Cliff! We could also take a run at the final NextEngine scan data using Geomagic DesignX if you can share your scan? Happy to help in any way that I can (seldenjrz@sfasu.edu).
