Measurement of the percentage volume of the ivory constituent of a composite object is necessary to ensure compliance with the ivory volume provision in California Fish and Game Code (FGC) section 2022. Assessment of the ivory percentage must be conducted as a percentage of the total volume of the composite object and be of a non-destructive nature. To meet these analytical requirements, optical three-dimensional (3D) scanning and imaging software algorithms were used to create 3D models of three composite objects and to measure the volumetric percentage of the ivory constituents. Volumetric percentage determination of the ivory constituents was conducted on the composite objects in both the assembled and the disassembled states to assess the percentage error (PE) for ivory volume measurements when destruction of an item is not permitted. For objects or carvings with clearly defined boundary lines, a PE of |
