Embodiment Construction

[0043] The invention adopts a cluster rendering method based on parallel image codec and transmission, effectively reduces the time overhead of image processing, and simultaneously reduces the occupied space of network bandwidth.

[0044] The system for implementing the cluster rendering of the present invention is mainly composed of five parts: a management server for dividing tasks, a cluster node for processing subtasks, a GPU thread for rendering and decompressing subtasks, and a subtask for storing subtasks. A buffer for task processing results and a display server for displaying processing results.

[0045] Method of the present invention comprises the steps:

[0046](1) The management server divides a picture with a rendering task of 1920×1080 into tasks, divides the picture into 100 tasks of 192×108, and labels each subtask as subtask 1, Subtask 2, subtask 3...subtask 100. In this embodiment, 5 computers are used for collaborative rendering, and the 100 subtasks are ...

Abstract

The invention discloses a cluster rendering method based on image decoding and decoding and parallel transmission. According to the invention, a task is divided into independent sub-tasks; calculated quantity between different cluster nodes is effectively balanced; a machine with weak calculation ability also can be added to the cluster system; the expansibility of the system is effectively improved; and the time consumption for image processing can be effectively reduced by a sub-task rendering and parallel transmission mode, and the network transmission expenses are effectively reduced by combining with encoding and decoding of the image. Compared with the traditional method, the FPS (frame per second) disclosed by the invention is higher, a display interface is smoother, and the system performance is effectively improved.

Description

technical field [0001] The present invention relates to a cluster rendering method, in particular to a cluster rendering method based on parallel image codec and transmission. Background technique [0002] High-realistic rendering has been used more and more, and it plays an important role in the production of movie special effects and the display of realistic scenes. High-realistic rendering requires extremely high computing power. If we have high requirements for rendering speed, then the rendering capabilities of a single machine can no longer meet it. At this time we need to use cluster technology. [0003] A cluster is a group of independent computers interconnected by a high-speed network that form a group and are managed as a single system. When a client interacts with the cluster, the cluster behaves like a stand-alone server. Clusters can improve processing performance, reduce costs, increase scalability, and enhance reliability. [0004] A very key technology i...
