Abstract

The invention provides a method and a device for drawing a large-scale scene at fixed frame rate based on the features of model components. The method comprises the following steps: acquiring parameter information of model components, and creating component nodes and shared component nodes according to the parameter information; acquiring the features of the model components, and creating multi-level detail rendering nodes according to the features and the parameter information; recursively building a spatial octree scene tree according to the component nodes and the shared component nodes; carrying out dynamic screening according to the distribution information of the model components and the spatial octree scene tree to get a visible component set; and carrying out multi-level detail dynamic drawing of the model components according to the visible component set, the multi-level detail rendering nodes and preset drawing conditions. A large-scale process plant model can be loaded and designed through a process plant design platform, and the frame rate can be displayed and controlled. Moreover, the design scale and the interaction frame rate can both be improved significantly.

Description

technical field [0001] The invention relates to the field of three-dimensional process factory design, in particular to a large-scale scene fixed frame rate rendering method and device based on model component features. Background technique [0002] The process plant design platform is an indispensable support base for modern process plants from design, construction to operation management. Supporting the drawing of large-scale scenes is a key issue in the current process factory design platform. For now, most of the CAD design platforms, under the general computer configuration environment, can easily lead to problems such as crashes and low drawing frame rates after loading and importing a certain scale of process factory models, which are not enough to support the increasing scale of our country today. The design of the process factory model needs. [0003] Therefore, supporting the design and interaction of process factory models for large-scale scenarios and keeping t...
