| 摘要 |
A system and method for modeling three-dimensional objects such as diamonds and other gemstones. A three-dimensional finite-element model obtained by, for example, analysis of boundaries of the object in photographs taken from multiple perspectives with frontal lighting or silhouette lighting, or by analysis of structured-light photographs of the object taken from multiple perspectives, is combined with color or grayscale information obtained from photographs of the object. Enhanced or "false" color can be used to improve the viewing experience or to emphasize particular features of the object. A computer can rotate the model about arbitrary axes according to the desires of a viewer.
