Online three-dimensional rendering technology and system based on cloud platform

Abstract

The invention discloses an online three-dimensional rendering technology and system based on a cloud platform, the system comprises a WEB front-end system, the WEB front-end system comprises an accesslayer and a front-end UI, and the access layer comprises a mobile phone and a PC terminal. A communication layer, a service layer and a data layer, a model subtraction optimization algorithm is adopted to carry out lightweight processing on a model file; a step of compressing a lightweight model after surface reduction optimization and a step of optimizing a model file through a real-time communication protocol are included. In addition, a parallel algorithm and a dynamic computing power rendering algorithm of a rendering pipeline are adopted to carry out lightweight processing on the model file; a user can obtain high-quality 3D rendering on any lightweight terminal; according to the online three-dimensional rendering system of the cloud platform, a product in a design is rendered and generated in the cloud server, designers from various countries or various regions can design in the same platform and directly communicate with each other to see a law and make a conclusion, and the modified design is verified together.

Description

technical field [0001] The invention relates to the field of three-dimensional rendering on a cloud platform of architectural software, in particular to an online three-dimensional rendering technology and system based on a cloud platform. Background technique [0002] With the development of computer visualization and virtual reality technology, people put forward higher requirements for real-time realistic rendering and scene complexity. The traditional direct use of low-level graphics interfaces such as OpenGL and DirectX to develop graphics application models has the disadvantages of high development complexity, long cycle time, and difficult maintenance. Conventional commercial rendering engines, such as Delta3D, OGRE, OSG, Unity3d, VTK, etc., have the characteristics of high cost, no open source, and high requirements for graphics cards and hardware, which is not conducive to the collaborative work of the BIM application industry. [0003] The working mode of the onli...

Problems solved by technology

[0005] However, the online 3D rendering system of the cloud platform may face rendering requests from thousands of users, which will put enormous pressure on the back-end server system. When cloud rendering meets the needs of the same number of users, the required The time-consuming hardware performance is at least several times to dozens of times higher than that of cloud computing, which means that the computing system that provides cloud rendering services will be very large

Therefore, the cloud rendering system requires the server container to have high-speed graphics performance and real-time scheduling algorithm, otherwise it cannot meet the simultaneous rendering requests of a large number of users
