我们描述了一种交互式渲染生物纳米结构（例如蛇皮表面光栅）产生的衍射效应的技术。我们的方法使用来自原子力显微镜的图像，该图像准确地捕获了负责结构着色的纳米结构的几何形状，即由于波干涉而导致的着色，在各种动物中。我们开发了一种渲染技术，直接从测量数据构建双向反射分布函数（BRDFs），并利用预计算来实现交互性能。我们展示了我们的方法使用各种形状的表面光栅纳米结构的结果。最后，我们评估了我们的基于预计算的技术的准确性，并与参考BRDF构建技术进行比较
We describe a technique for interactive rendering of diffraction effects produced by biological nanostructures, such as snake skin surface gratings. Our approach uses imagery from atomic force microscopy that accurately captures the geometry of the nanostructures responsible for structural colouration, that is, colouration due to wave interference, in a variety of animals. We develop a rendering technique that constructs bidirectional reflection distribution functions (BRDFs) directly from the measured data and leverages pre-computation to achieve interactive performance. We demonstrate results of our approach using various shapes of the surface grating nanostructures. Finally, we evaluate the accuracy of our pre-computation-based technique and compare to a reference BRDF construction technique
