Browser-based construction system of three-dimensional ultra-large scene

Abstract

The invention discloses a browser-based construction system of a three-dimensional ultra-large scene, comprises a scene photo manager, a three-dimensional original shared library, a three-dimensional scene webpage editor, a three-dimensional navigation map generator, a scene light-effect embedder, a simulated natural environment generator and a three-dimensional webpage exporter which work together to finish the construction of the three-dimensional ultra-large scene. The invention uses a website-type collaboration platform with a uniform server, does not store files in a local workstation, thereby ensuring multiple calling and uploading and the coordinate synchronization of file updating, greatly improving the group collaboration efficiency and shortening the construction period of the ultra-large scene; and the invention uses a webpage as a working platform, checks the finally three-dimensional display effect and the webpage rendering performance at any time, controls the balance relation between model fineness and issuance performance in time, greatly reduces the capacity of three-dimensional scene files and effectively controls the redundancy of large-scene shared sources.

Description

technical field [0001] The invention relates to the technical field of building three-dimensional virtual scenes, in particular to a browser-based multi-person collaborative building system for three-dimensional super-large scenes. Background technique [0002] In the traditional 3D scene construction method, large scenes are always broken down into small scenes for different producers. The unification of naming is implemented by management standards, and is not directly embedded in the production process. Incorrect naming usually leads to wrong display of models or materials, and repeated naming between multiple scenes, especially the naming of the diffuse reflection layer of materials is difficult to change in batches, and it is difficult to find out in time, which has become a problem for many pure browser 3D A puzzle for games, VR projects. Even tools like 3DPI, which have been popular in the world for many years to assist webpage 3D game development, cannot realize mul...

Problems solved by technology

Incorrect naming usually leads to wrong display of models or materials, and repeated naming between multiple scenes, especially the naming of the diffuse reflection layer of materials is difficult to change in batches, and it is difficult to find out in time, which has become a problem for many pure browser 3D A conundrum for games, VR projects

Even tools like 3DPI, which have been popular in the world for many years to assist the development of 3D web games, cannot realize multi-person collaboration because they are not networked.

[0003] A large scene constructed in the traditional way is always composed of multiple decomposed 3D scene files. At this time, there will be a large number of repeated texture maps and common models between each sub-scene file, which will greatly increase the total file capacity.

[0004] Moreover, the production of large scenes can only be broken down from the management point of view. Almost every producer needs to do all the tedious work except modeling. It is difficult to achieve the division of labor and cooperation with the ability to divide high and low

[0005] The scene production of web games is always done after the 3D scene is produced and the file is exported, and then the effect can be viewed through the browser. If there is any problem, enter 3dmax to adjust and then export for inspection. However, the preview tool that comes with 3dmax has a single function, showing the effect and There is a certain gap in the display effect in the browser, and it is impossible to accurately find the bottleneck position that affects real-time rendering
