Creation of Electronic 3D Model of Sculpture


A computer 3D model of a steel sculpture was created for analysis purposes from a physical scale model. Due to the geometric complexity of the sculpture, an innovative method was used to generate the computer model. The approach used was the utilization of “reality catch” technology that analyzes still photographs to generate a 3D mesh by triangulation of unique identifiable points in the still photographs. The mesh was then exported to AutoCAD. The physical model was measured and cross-checked with the AutoCAD model to verify the accuracy of the mesh and was then refined to remove any errors and scaled to the final physical dimensions. At this point a 3D surface was generated in AutoCAD and exported to SAP2000 for analysis. The full-scale sculpture has been constructed and installed in San Diego, CA.
