Embodiment Construction

[0031] The present invention, that is, a virtual scene roaming method based on spatial index cube panoramic video, comprises the following steps:

[0032] (1) Spatial Index Cube Panoramic Video Acquisition

[0033] First, specify a path that the user can visit in the virtual scene, and use existing 3D software tools, such as 3DS Max, Maya, etc., to overcome the shortcoming that the cylindrical panorama restricts the user's vertical field of view, and use Cube Environment Mapping draws panoramic images. Cube environment mapping uses the cube's six faces to record all rays incident on the cube's center point.

[0034] The cube environment mapping sequence constitutes the cube panorama video, and the script language provided by the 3D software tool is used to program to obtain the spatial index information corresponding to each panorama, which is compared with the existing spatial index acquired through image post-processing technology and GPS. Compared with information, this m...

Abstract

A virtual scene roams method based on spatial index cube panoramic view video and a system thereof are disclosed. The system includes a motion control engine unit, a panoramic view video protract unit, a sound protract unit, a mapping unit and a text display unit, wherein the motion control engine unit is connected to an external input device and receives the spatial index cube panoramic view video signal input from external, the corresponding sound file of the roam paths, control map and text information. The invention executes fine model building for the virtual scene by existing three-dimensional tools, pre-protracts the required high quality image sequence, and compresses the panoramic view video data and improves the protracting speed by choosing the spatial index cube panoramic view video as input and using the compressing method supported by a three-dimension graphics card. The user can conveniently interact with the system by external instruments such as game handle; mouse and keyboard to obtain high quality roam experience.

Description

technical field [0001] The invention relates to a virtual scene roaming method and system thereof, in particular to a virtual scene roaming method and system based on spatial index cube panoramic video. Background technique [0002] The virtual scene roaming system usually uses three-dimensional geometry and its texture information to describe the objects in the scene, and uses algorithms similar to those in video games to draw the scene in real time. This type of system requires a lot of tedious manual interaction to complete the geometric simplification and texture optimization of the 3D model, so as to reduce the amount of data and achieve the purpose of real-time rendering. Simplified representation sacrifices the accuracy of the model, thereby reducing the quality of the drawn image. In addition, the processing capabilities of current personal computers (PCs) and 3D graphics cards are still limited, and high-quality realistic graphics generation technologies, such as r...
