An Interactive Procedural Modeling Method for Pipelines basedon Profile Point Projection Algorithm

现代工业管道建筑管网布线复杂精细,对设备模型曲面的精细化表达有更高的要求。同时,追求网格模型的精确与高效的开发效率是模型开发人员的迫切愿望,对工业管道进行精确的图形描述和简化工业管网的工作流水线成为该领域的研究重点。提出一种改进的基于样条的管道剖面轮廓点位置投射计算方法,从现有的非分割管道网格中提取曲线控制节点,为用户提供可编辑的初始框架并完成管道网络的拼接。实验结果表明,该方法可用于工业领域中各类型管道或类似设备模型的仿真建模。构建框架和组件易于编辑,对非专业用户友好,具有高效性和高容错率。

Modern industrial pipeline building network wiring is complex and fine,so it has higher requirements for the refined representation of equipment model curved surfaces.At the same time,the accurate and efficient development ef-ficiency of mesh models is an urgent desire of model developers,and accurate graphical descriptions of industrial pipe-lines and simplification of the working pipeline of industrial pipeline networks have become the focus of research in this field.Therefore,an improved spline-based method for projecting the position of pipeline profile points is proposed in this paper,which can extract curve control nodes from existing non-segmented pipeline meshes,thus providing users with an initial editable framework and completing the stitching of pipeline networks.The experimental results show that the meth-od can be used for simulation modeling of various types of pipelines or similar equipment models in the industry.The construction framework and components are easy to edit,friendly to non-expert users,efficient and highly fault-tolerant.
