Problems solved by technology

The disadvantage of this method is that users need to wait too long
Although this transmission mode enables the user to see the display of the model quickly, the user still has to wait a long time to see the detailed model effect

Embodiment Construction

[0033] The present invention adopts the Client-Server mode, and realizes the structure as figure 1 shown.

[0034] 1. Client

[0035] Users can observe the 3D model through the 3D client browser provided by the system. The client program contains a simplified 3D model with a very low resolution, and the user can perform interactive operations such as rotation, scaling, and translation on the rough model. When the user stops the operation (the program detects that the user has stopped the operation through the MouseUp message), the client program sends a rendering request to the remote rendering server through the network, and the request includes the current user's viewpoint position, direction and the transformation matrix that controls the state of the 3D model ;The server renders the high-resolution model on the server side according to these information and obtains a high-resolution rendered image, and then sends it to the client, and the client uses it to replace the cu...

Abstract

The invention relates to a publish method for three-dimensional model network based on remote romance. The invention comprises: storing high accurate model in the romance server; the three-dimensional browser of client terminal only provides large simple coarse model; user can zoom, move, and rotate said model at the client model to select best sight point; when user stops the operation, the client terminal sends a romance request to the server while said request contains the information as present sight point, direction and illumination condition; the server according to the request of client terminal processes the romance and returns the photo of high accurate model. Since the sensitive high accurate model is stored in the client terminal, the invention has safety advantage; since the client terminal and the server exchange the photo whose average size is 30KB only when the user stops the operation, the invention has lower demand for network; and the client terminal only romance simple model without needing high graphic property.

Description

technical field [0001] The present invention relates to the technologies of three-dimensional model simplification, three-dimensional data security and remote rendering, in particular a remote rendering three-dimensional model network release method, which is applied to the network release of various three-dimensional models. In addition, it is also applied to the network publishing of 3D models of precious cultural relics in digital museums. Background technique [0002] In order to obtain the simplified model of the client, it is necessary to simplify the high-precision 3D model. The research on 3D model simplification started with the vertex deletion method of Schroeder et al. in 1992, Hoppe proposed the grid optimization method of energy function in 1993, Cohen proposed the method of simplifying the envelope in 1996, Garland in his doctoral thesis The quadratic error method is proposed in . [0003] In terms of 3D data security, most of the research at home and abroad ...
