Multi-channel real-time three-dimensional vision rendering indication method

Abstract

The invention relates to a multi-channel real-time three-dimensional visual scene rendering display method, which adopts multi computer and double networks to transmit data through a UDP protocol on a visual scene subnet. System time is divided into barrels with equal time intervals according to render frame rate; each DDU is associated with a timestamp when being computed, and the timestamp indicates which barrel the data is associated with. Moreover, a timestamp is arranged into and written into each DDU; DDU buffer areas are arranged on a receiving side; forwarding time of DDUs are adjusted backwards; when timestamps of the DDUs are matched with render time, rendering is performed, thereby jitter is effectively prevented. Simultaneously, a two-step linear method is adopted to forecast positions and statuses of next frames of various moving targets, namely information of an n+2 frame is forecasted if target positions of an n frame and an n+1 frame are known. When the DDUs are lost, rendering is performed according to forecasted data. The invention successively solves the technical problem of real-time rendering of multi-channel three-dimensional visual scenes by a plurality of microcomputers and satisfactorily realizes frame synchronization under multi-computer distribution collaborative environment, and smooth display effect is obvious.

Description

(1) Technical field [0001] The invention relates to a computer three-dimensional image simulation processing method, in particular to visual scene rendering processing, in particular to a multi-channel real-time three-dimensional visual rendering display method. (2) Background technology [0002] Most of the simulation processing of computer 3D images requires a rendering process. There are three existing multi-channel real-time 3D rendering display methods: [0003] The simplest way is to divide the picture rendered by one processor in real time into multiple signals, and send the multiple signals to the displays in the display array respectively. Although this method can increase the size of the display, the resolution of the display remains unchanged. For example, if a 1280×1024 three-dimensional picture is enlarged to occupy the screen responsible for four 1280×1024 projection units, the accuracy of the information is still 1280×1024, but each pixel of the original sign...
