Problems solved by technology

Therefore, material files can be repeatedly referenced in multiple rendering tasks, and since rendering project files are created by rendering-related producers using modeling tools such as 3dsMax and Maya according to requirements, rendering project models often do not have repeatable availability;

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings and specific embodiments of the specification.

[0026] In order to achieve the purpose of the present invention, this embodiment provides a high-speed transmission method for cloud rendering files based on rendering characteristics, such as figure 2 As shown, the method includes the following steps:

[0027] 1. The technical system disclosed in the present invention includes two systems, the client system and the network storage server, such as figure 1 As shown, the network file Hash value judgment principle system diagram of the present embodiment.

[0028] 2. After the user starts uploading rendering files through the rendering client, the system executes the file queue checking process:

[0029] 2.1 Form the file to be uploaded in the local storage path into an initialization list 2-01 of the file to be uploaded, and the list is sorted from new to old based on the last modific...

Abstract

The invention discloses a cloud-rendering file high-speed transmission method based on rendering characteristics. A file checking list forms in a client system, and files which are the same with files in a network storage server are rejected. According to the invention, through file modification time and file size sequencing, a file which needs to be uploaded is searched. While uploading the file, the system begins to calculate Hash characteristic values of the next file. Through sending Hash value contrast to a server side for two times, a to-be-uploaded file, in the a client side, which is the same with files in the server side, is deleted. No computational complexity is increased, and simultaneously the quantity of file uploading can be reduced to the limit, and the total time consuming of file uploading can be reduced. According to the system, the file uploading efficiency is greatly raised; for industry characteristics of frequent uploading and downloading of large files of the rendering industry, storage space of the network server can be saved considerably. Meanwhile, time spent on uploading by clients is reduced.

Description

technical field [0001] The invention belongs to the technical field of computer multimedia, and in particular relates to a high-speed transmission method of cloud rendering files based on rendering characteristics. Background technique [0002] At present, there are various ways of internet file transmission, for example: "A Method for Transmission of Free-viewpoint Video Based on Light Field Rendering in IP Network", Publication No. 101022537, the invention relates to a transmission method of free-viewpoint video based on Light Field Rendering in IP network The method is to cache the compressed video stream of the video collected by each computer from the camera as a video stream; to transmit the multiple video streams required by the user as a free viewpoint video stream. The transmission method includes: video stream Cache; establish a connection preparation service, put the user and the required video stream number into the corresponding user to-be-served list, and the u...
