Abstract

The present invention provides a large-scale scene fixed frame rate rendering method and device based on the characteristics of model components. The method includes: acquiring parameter information of model components, creating component nodes and shared component nodes according to the parameter information; acquiring features of model components, and and parameter information to create multi-level detail rendering nodes; recursively construct a spatial octet scene tree according to component nodes and shared component nodes; obtain the visible component set according to the distribution information of model components and the spatial octet scene tree dynamic screening; according to the visible component set, multiple The level-detail rendering nodes and preset drawing conditions dynamically draw the multi-level details of the model components, which can effectively realize the loading and design of large-scale process plant models on the process plant design platform and achieve the effect of display control frame rate. The design scale and interaction frame rate can be significantly improved.

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...
