The mathematical expression and the topological construction of the new model are presented. 提供了该预测模型的数学表达式和拓扑结构。
The Screw Thread shading network is a good example of how displacement can be driven by a mathematical expression rather than a conventional texture map. 螺纹材质网络是一个好例子，它证明了如何通过一个数学表达式来驱动置换，它强于一个方便的纹理贴图。
