Problems solved by technology

[0003] At present, it is generally used to directly add 3D special effect processing to the original roaming information content. This technical processing method has certain technical limitations, especially the 3D special effect rendering processing is complicated, occupies system resources, and affects rendering efficiency.
In addition, the existing patent application number is 200810223666.8, and the title of the invention is "A Realization System for Real-time Bottom Flying". The technical solution proposed has no judgment on the rendering of data volume, and cannot improve the efficiency of data rendering

Embodiment example

[0036] Further, as attached Figure 4 As shown, it is a schematic diagram of the object envelope generation method. Here, we use a cube and a sphere as a specific implementation case. The specific steps are as follows:

[0037] Generate the 3D mesh of the object according to the object parameters and the content transmitted by the real-time information.

[0038] Generates an envelope for the object based on the mesh.

[0039] Transforms the envelope according to the object's position, scale, and rotation information.

[0040] attached Figure 5 The processing method for the intersection test of the object envelope and the final clipping area to find the minimum set that needs to be processed at the end, thereby reducing the workload of rendering.

[0041] Intersect the envelopes of object-1, object 1, object 2, object 3, object 4 and object 5 with the final clipping area 303, and set if the intersection area of ​​the object envelope and the final clipping area 303 If it is...

Abstract

The invention relates to the graphic image processing technology in the radio and television field, in particular relates to a method for realizing real-time information wandering in a three-dimensional scene. The method comprises the following steps: acquiring a wandering information template which needs to be manufactured from a template library; finding the clipping region of the template in the three-dimensional space; interactively clipping the clipping region with a screen to obtain a final clipping region; leading collected real-time data into a material template to generate a corresponding object; according to different applications, tidying into object linkage lists belonging to different groups; according to movement velocity and movement direction, adjusting the positions of each group of objects in the three-dimensional space; calculating an object enveloping solid obtained after each object is subjected to three-dimensional transform; calculating the crossing test situation of each object enveloping solid and a final clipping region; rendering the crossing position, and requiring no rendering on the non-crossing position; repeating the above steps if new real-time is provided until all required data is rendered and played; and exiting.

Description

Technical field: [0001] The invention relates to the technical field of graphics and image processing in the field of radio and television, in particular to a method for realizing real-time information walking in a three-dimensional scene. Background technique: [0002] With the development and progress of 3D graphic packaging technology, the application of 3D graphic in the field of radio and television is becoming more and more extensive. At the same time, during the broadcasting of various live programs, such as serial broadcasting of TV programs, reports of major emergencies, financial news, live broadcasts of large-scale sports events, and large-scale special live broadcasts, the amount of real-time information broadcasting increases, and real-time information wanders. Broadcast form has become a commonly used way of expression. [0003] At present, it is generally used to directly add 3D special effects processing to the original walking information content. This tech...
