3D扫描仪在建模过程中会创建大量的点数据，因此需要减少点数据。然而，在这样的过程中，模型细节，如浮雕和表面图案，往往被删除。纹理可以添加表面细节，这些细节通常过于复杂，无法直接使用图像，数值函数或其他数据源进行建模。凹凸贴图可以使用着色效果来表示三维细节。本研究的重点是从三维扫描数据生成凹凸贴图，以补偿在建模过程中丢失的细节。这里介绍的凹凸贴图很容易识别，因为它们是在模型被平面和圆柱基平面细分后生成的。这有助于凹凸贴图的修改及其在其他模型中的进一步应用。
A 3D scanner creates a large amount of point data during modeling process and, therefore, it requires point data reduction. However, during such process, model details, like the relief and surface pattern, is often removed. Texturing can add surface details that are usually too complex to be modeled directly using images, numerical functions or other source of data. Bump mapping can represent three-dimensional details using shading effects. This study focuses on the generation of bump maps from 3D scan data to compensate for details that are lost during the modeling process. The bump maps introduced here are easily recognized since they are generated after the model is subdivided by planar and cylindrical base planes. This facilitates the modification of bump maps and their further application to other models.
