The goal of this project was to scan and reverse engineer one of three bronze cannons (41MG86 - 11900-1) recovered from the La Belle excavation, which is currently on exhibit at the Bullock Texas State History Museum in Austin, Texas. A freeform computer aided design (CAD) model was generated based upon the topology of the three-dimensional (3-D) mesh in Geomagic Design X with a desired maximum deviation of 0.1 mm between the model and the mesh. Deviations were calculated in Geomagic Control X using the surface model as the reference data, and the mesh as the measured data. A custom patch network was subsequently designed using a series of iterative revisions until the whole of the surface model met with the specified tolerance. The 3-D surface model of the cannon will be replicated in a variety of media at variable scales for use in exhibits and for educational and promotional material for the Texas Historical Commission, the Republic of France, and their partner museums.

该项目的目标是对从La Belle回收的三门青铜加农炮（41MG86-11900-1）中的一门进行扫描和逆向工程挖掘，目前在德克萨斯州奥斯丁的布洛克德克萨斯州历史博物馆展出。基于Geomagic Design X中三维（3-D）网格的拓扑生成了自由形式的计算机辅助设计（CAD）模型，模型与网格之间的最大期望偏差为0.1 mm。在Geomagic Control X中使用表面模型作为参考数据，并以网格作为测量数据来计算偏差。随后使用一系列迭代修订来设计自定义贴片网络，直到整个表面模型达到指定的公差为止。加农炮的3-D表面模型将以各种比例复制到各种媒体中，以用于展览以及得克萨斯州历史委员会，法兰西共和国及其合作伙伴博物馆的教育和宣传材料。
