Procedural Modeling Method of Pipe Network Based on Spline Grammar

Abstract

The shape grammar is usually used to describe the three-dimensional model with certain regularity, but in the process of constructing the three-dimensional model of industrial pipeline network or urban underground pipeline network, due to the complex wiring characteristics of the pipeline, the pipeline with different changing trajectories is often unable to be described by fixed shape. Therefore, the construction process for 3D pipe networks often requires art developers to spend a lot of time and effort to develop models. Arbitrarily shaped pipes can be effectively described in procedural modeling construction processes by incorporating splines that are inherently variable in nature and combining them as terminator shapes into shape grammar. Based on this theory, this paper proposes that the procedural modeling method based on spline grammar can efficiently complete the procedural construction of pipeline networks, and this method can quickly complete the splicing of pipeline networks. Experimental results show that our method is suitable for pipe network construction projects in different fields.
