我们提出了一种使用图形硬件实时渲染多面彩色宝石的算法。除了处理此类物体中光的复杂行为的技术挑战之外，宝石的实时高质量渲染还直接应用于珠宝原型制作领域，该领域现已成为取代繁琐（且交互性较差）蜡雕方法的标准做法。我们的解决方案基于光进入石头时所涉及的物理现象的许多受控近似，这允许基于最新但普遍可用的硬件功能（例如片段程序、立方体映射）来实现。
We present an algorithm for rendering faceted colored gemstones in real time, using graphics hardware. Beyond the technical challenge of handling the complex behavior of light in such objects, a real time high quality rendering of gemstones has direct applications in the field of jewelry prototyping, which has now become a standard practice for replacing tedious (and less interactive) wax carving methods. Our solution is based on a number of controlled approximations of the physical phenomena involved when light enters a stone, which permit an implementation based on the most recent -- yet commonly available -- hardware features such as fragment programs, cube-mapping.
