Abstract

The invention relates to a method for automatically modeling and rendering a mass of 3D cable and channel model and belongs to the technical field of urban cable management automatic modeling. The method comprises steps of: performing modeling by constructing a parameterized model of a cable and channel object and by establishing a parameter driving mechanism; producing a cable and channel 3D model by parameterized modeling technology according to an actual size; performing hierarchical management on a mass of cables and auxiliary equipment, setting model octree space division, achieving efficient query and smooth rendering of the model by using resource asynchronous scheduling. The method achieves parameterized modeling of the cable model, greatly decreases manual modeling workload and manual modeling fund investment, enhances the update timeliness of the cable 3D model, reduces a configuration requirement for user hardware equipment, improves scene rendering smoothness, and provides necessary technical support for display, daily maintenance, and planning of a mass of underground cables.

Description

technical field [0001] The invention relates to an automatic modeling and rendering method for massive three-dimensional cables and channel models, and belongs to the technical field of automatic modeling for urban cable management. Background technique [0002] In recent years, the rate of domestic urban cables has increased rapidly, and the management of underground cables by power companies has gradually shifted from two-dimensional CAD graphics and drawings to three-dimensional digital management. With the improvement of 3D modeling software and the improvement of computer hardware performance year by year, the popularity of 3D rendering engines (Ogre, OSG, WorldWind) has derived a series of artificially built models based on 3D modeling software (AutoCAD, Pro / E, UG, CATIA, etc.). 3D cable display management system for the model. Although the current modeling software can manually carry out three-dimensional modeling of underground cables, manual modeling has a large w...
