Problems solved by technology

[0004] from Figure 1A and Figure 1B It can be seen that although the existing technology can display the videos of the participating parties, they are all displayed in a single rectangular manner, resulting in a poor overall display effect and poor user experience when displaying videos from multiple parties.

Embodiment Construction

[0039] In this embodiment, when displaying videos of multiple parties involved in the communication in instant messaging, the original simple rectangular display mode is broken, and part or all of the videos are displayed in polygonal display areas other than rectangles, so as to present a three-dimensional effect between videos. For example, non-right-angled parallelograms, pentagons, hexagons, etc. Further, the reflection of the video facing up is displayed to enhance the stereoscopic effect.

[0040] In this embodiment, the Direct3D display technology is used, and the image texture of the rectangular mode is mapped to the rectangular video display area and other polygonal video display areas for displaying video through Direct3D texture mapping. The following briefly describes the Direct3D display technology used in this embodiment.

[0041] Since the three-dimensional world is composed of points, lines, and surfaces, they correspond to vertices, lines, and triangles in Di...

Abstract

The invention discloses a method for displaying the multiparty video in the instant communication. The method comprises the processes that: a plurality of polygonal video display zones in which the multiparty video is displayed in the instant communication is determined and a plurality of polygonal video display zones wherein take a three-dimensional shape in the display space; the video needing to be displayed is respectively segmented into the triangles and the corresponding video display zones are segmented into the same number of the triangles, and the corresponding relation between the video texture vertex of the triangle after being segmented and the triangle vertex of the display zone is determined according to the mapping relation; the video texture is mapped to the corresponding zone according to the corresponding relation between the triangle vertexes and the transform or zooming processing is applied to the video texture in the video display zone, and the video images in a plurality of polygonal video display zones are displayed. The invention further simultaneously discloses a device for displaying the multiparty video.

Description

technical field [0001] The invention relates to video technology in instant messaging, in particular to a method and device for displaying multi-party video in instant messaging. Background technique [0002] The network instant messaging tool has been developed to this day and has been accepted by most network users, and has gradually become an indispensable part of the daily life of the users. The existing instant messaging system can provide a video chat function, and multiple users can not only communicate through text messages and voice, but also transmit and display images of each other. [0003] In the existing instant messaging, a rectangular display area is used to display the videos of the communicating parties. Figure 1A It is shown that the image of the communicating party is displayed on the display device (the blurring process in the figure is used to protect privacy, not for display effect, the same below). Figure 1B Shown is an image of multiple parties pa...
