SBIR Phase I: Volume and Surface Mesh Improvement of 3D Shapes

*9760229 Facello这个小型企业创新研究第一阶段项目将探索一种新的方法，为3D模型自动生成高质量的曲面和体积网格。即将开发的软件将是该公司Wrap的关键扩展，Wrap根据任意3D点数据重建表面和实体，提供直接从3D扫描仪的输出自动生成高质量表面和体积网格的能力。目前，网格生成通常是与建模软件分开的单独的软件包，而创建有限元分析(FEA)模型是一个耗时的过程，需要将计算机辅助设计(CAD)模型乏味地转换为FEA模型，或者在FEA环境中构建新的复制模型。无法自动生成局部质量有保证的网格，阻碍了用于分析复杂几何形状的数值方法。该软件模块如果成功实施并与Wrap相结合，将解决网格生成中最困难的问题之一。曲面重建和网格改进的集成提供了一个紧凑的解决方案，该解决方案将从逆向工程问题的建模和网格生成的完全集成和自动化中节省大量时间并使其易于使用。***

*** 9760229 Facello This Small Business Innovation Research Phase I project will explore a novel approach to automatic quality surface and volume mesh generation for 3D models. The software to be developed will be a critical extension to the firm's Wrap that reconstructs surfaces and solids from arbitrary 3D point data, providing the ability to automatically produce quality surface and volume meshes directly from the output of 3D scanners. Currently, mesh generation is often a separate package apart from the modeling software, and the creation of a finite element analysis (FEA) model is a time consuming process requiring a tedious translation of the computer assisted design (CAD) model into an FEA model or the construction of a new, duplicate model in the FEA environment. The inability to automatically generate meshes with guaranteed local quality has hampered the numerical methods used to analyze complicated geometric shapes. The software module, if successfully implemented and combined with Wrap, will solve one of the most difficult problems in mesh generation. The integration of surface reconstruction and mesh improvement provides a compact solution that will enable both important time savings and ease of use from the total integration and automation of modeling and mesh generation for reverse engineering problems. ***
