Method, system and platform for distributed type three-dimensional (3D) multichannel rendering

Abstract

The invention provides a method, a system and a platform for distributed type three-dimensional (3D) multi-channel rendering. The method comprises the steps that a control terminal sends a rendering instruction to rendering channels according to a preset rendering indexed list; the rendering channels render corresponding sub-scene-images according to the received rendering instruction; after rendering is finished by the rendering channels, the control terminal sends a display instruction to the rendering channels; and the rendering channels display the corresponding sub-scene-images when receiving the display instruction. By means of the method, the resource utilization rate of the rendering channels can be improved, the display frame rate of a splicing wall 3D visual application can be effectively improved, computer parallel cooperative work characteristics can be better reflected, fast integration with an existing splicing wall system is achieved, expansibility is high, and the 3D visual application of a splicing wall can be popularized conveniently.

Description

technical field [0001] The invention relates to the field of distributed multi-computer parallel computing, in particular to a distributed 3D multi-channel rendering method, system and platform. Background technique [0002] 3D rendering is to complete the image conversion process from the three-dimensional scene data generated in the computer to the two-dimensional display plane. In practice, the most widely used is the 3D GIS rendering system. The 3D GIS system is an organic combination of three-dimensional visual rendering and geographic information system. product of. 3D visualization technology has been widely used in military, aviation, aerospace, medicine, geological exploration, cultural entertainment and artistic modeling. [0003] figure 1 It is an existing 3D multi-channel rendering method based on a distributed computer architecture. The distributed multi-channel stores 3D data on different computer nodes to achieve parallel rendering processing. The entire clu...

Problems solved by technology

[0005] (1) The hardware configuration of the rendering node machine is generally required to be the same, and the rendering output resolution is also required to be the same. Otherwise, when roaming the scene, a low-end hardware configuration will inevitably reduce the display frame of the entire cluster system when encountering a complex scene. Rate;

[0006] (2) Each rendering node can only render a fixed segmented content of the entire scene wall. For example, if the entire scene wall is rendered by two nodes, rendering node 1 can only render the content of the left side of the scene wall. Rendering node 2 can only render the content on the right side of the screen, that is to say, rendering node 1 cannot render the content on the right side of the screen during rendering

At present, the existing distributed 3D rendering solution is to use high-end display cards to replace the original low-end display cards. In this way, due to the high cost of high-end display cards, the cost of viewing 3D applications on the customer's splicing wall is increased.

On the other hand, in practice, it is necessary to change the original configuration of the customer, and it will cause waste to the original computer system configuration, which is not conducive to the promotion of 3D visualization applications among customers
