摘　　要：在动画项目制作过程中常常需要制作印痕类的物体建模,采用传统手动方式既费事费力,也无法保证建模的真实性和准确性。文中以三维脚印制作为例,利用MEL语言编写了能快速建模的Maya模块。该模块通过分析脚底与地面的接触关系,计算出地面出现脚印的形状、深浅和时间,再利用bump mapping凹凸纹理映射法及Displacement mapping位移贴图法根据脚印贴图序列制作出地面上的三维脚印。这个模块制作三维脚印的原理同样可以用在其他三维印痕的制作。In the process of making animation project, it is often necessary to make the object modeling of imprints, and it is difficult to use the traditional manual method, and the authenticity and accuracy of the modeling can not be guaranteed. Taking the three-dimensional footprint making as an example, the Maya module which can model quickly is compiled by using MEL language. This module calculates the shape, depth and time of footprints by analyzing the contact relationship between foot soles and ground. Using bump mapping concave and convex texture mapping method and displacement mapping method, the three-dimensional footprints on the ground are made according to the footprint mapping sequence. This module can also be used in the production of other three-dimensional prints.
