Embodiment Construction
[0039] The scheme of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0040] The embodiment of the present invention discloses a method for real-time rendering of batches of three-dimensional situational object trails. The method adopts the idea of combining rendering batches to reduce the total calculation amount of single-frame rendering, and uses multi-threading technology and programmable pipeline technology to achieve CPU and GPU computing resources. Reasonable and full use has significantly increased the number of situational objects that can be displayed on the same screen and the rendering frame rate, and greatly optimized the user interaction experience. Such as figure 1As shown in , this method first cuts out the situation objects that do not need to be displayed in the CPU main thread, fills the filtered trail objects that need to be drawn in turn into the fixed-capacity single-batch re...

The invention discloses a batched three-dimensional situation target wake real-time drawing method and system. Mainly aiming at a large amount of wake point data continuously generated by the real-time situation in a battlefield environment analog simulation system, targets needing to display wakes are filtered out through a CPU, multiple rendering objects are spliced and combined to be renderingbatches as few as possible by means of the multithreading technology, by means of the CPU, wake points are expanded to be a ribbon shape, visual effect adjustment is conducted, and finally rendering is conducted on a screen. Accordingly, real-time three-dimensional rendering of batched situation wake data can be achieved, and the visual effect is the ribbon shape with the head to tail color and width gradient effect. Compared with the method of directly using a rendering engine, the real-time rending efficiency is significantly improved, and the process that a command and control system user senses massive situation running trajectory and characteristics is smoother.
Description
technical field [0001] The invention belongs to the field of computer graphics, and is particularly proposed for a new batch three-dimensional situational object trail real-time drawing method and system for the simulation system of a battlefield environment where too many trails generated by real-time situational objects affect user interaction experience. Background technique [0002] The new generation of battlefield environment simulation system has higher and higher requirements for the carrying capacity of the target situation display in the 3D digital earth. As a component of situational information, target trails have the functions of perceiving the target’s motion state, retracing the target’s trajectory, and predicting the target’s action intention. It plays a key role in rapid target recognition and also has three-dimensional real-time rendering requirements. In the 3D scene, the trail of the target is often displayed in the form of streamers. It is required to ex...
