Reproducing the internal and external anatomy of fossil bones. Two new automatic digital tools
Objectives: We present two new automatic tools, developed under the R environment, to repro-
duce the internal and external structures of bony elements. The first method, Computer-Aided
Laser Scanner Emulator (CA-LSE), provides the reconstruction of the external portions of a 3D
mesh by simulating the action of a laser scanner. The second method, Automatic Segmentation
Tool for 3D objects (AST-3D), performs the digital reconstruction of anatomical cavities.
Materials and methods: We present the application of CA-LSE and AST-3D methods to different
