The invention discloses a high-speed rendering method and
system for a three-dimensional large-scale dynamic net rack of a one-graph of a
power grid. The method comprises the following steps: generating three-dimensional
model parameters of a
power transmission line according to
tower account data; dynamically scheduling rendering of the three-dimensional model of the
power transmission line according to the visible area range;
slicing the power transformation multi-source heterogeneous three-dimensional data; optimizing a three-dimensional rendering pipeline of the
power grid graph; and three-dimensional net rack high-speed rendering is carried out through visual cone removal, LOD and instantiation rendering technologies. According to the invention, based on the
machine account data of the
power transmission line, accurate rendering of the three-dimensional line on one graph of the
power grid is realized through parametric modeling; for a multi-source heterogeneous
transformer substation model, three-dimensional slices in a unified format are formed through a scene division technology, and support of a power grid graph on a three-dimensional slice rendering pipeline is expanded; in order to improve the rendering performance, dynamic rendering scheduling is carried out on the three-dimensional net rack in the
viewport, repeated drawing of a large number of same devices is avoided, the performance overhead is reduced, and the performance
bottleneck of loading the large-scale three-dimensional net rack is effectively solved.
