Problems solved by technology

The key technology to establish a three-dimensional virtual environment is to study three-dimensional entities. The field environment in the virtual realm is indispensable, such as trees, mountains, clouds, highlands, and ocean waves used in virtual battlefields, virtual driving training and other scenes. , but the current 3D entity library does not have these elements

Embodiment Construction

[0010] In the following, the three-dimensional roaming system and working process of the virtual fractal scene will be further described in combination with examples of tree and mountain virtual scenes.

[0011] Such as figure 1 As shown, the virtual fractal scene three-dimensional roaming system includes a head-mounted display 6, a material generating unit 1, an entity construction unit 2, a VRML browser 3, a scene map editing unit 4, and a virtual scene browsing unit 5, wherein the head-mounted display 6 communicates with a data line The virtual scene browsing unit 5 is connected, the material file 8 generated by the material generating unit 1 is passed to the entity construction unit 2 and the virtual scene browsing unit 5 through the data interface 7, and the entity generated by the entity construction unit 2 can be passed to in the form of a VRML file 9 The VRML browser 3 can also be passed to the scene map editing unit 4 and the virtual scene browsing unit 5 in the form ...

Abstract

The invention relates to a 3D roaming system of virtual fractional scenes, including a material quality generating unit, an entity constructing unit, a VRML browser, a scene map editing unit and a virtual scene browsing unit, and its working flows: starting; initializing device; initializing scene; interactive processing: receiving the information including forward, backward, look-up, look-down, turning left and turning right, and making corresponding transformation on a 3D model and the observed state; calculating object information; pattern romancing processing; ending and otherwise returning to interactive processing recovering resources. It has the advantages of simple structure, low cost, convenient operation, fast generating of scene environment, etc, and perfects the virtual-reality entity base, applied to the requirements of virtual battlefield training and virtual driving training.

Description

technical field [0001] The invention belongs to virtual reality technology, in particular to a three-dimensional roaming system of a virtual fractal scene. Background technique [0002] Virtual reality technology first appeared in the United States in the 1960s, and achieved rapid development in the late 1980s and early 1990s. At the end of 1986, a NASA research team integrated a VR 3D environment, users can grasp a virtual object with their hands and manipulate it, and can communicate with the system with gestures. In 1990, a war game center was opened in Chicago, and many relatively mature software and hardware products were launched, but the cost was high and application promotion was difficult. Our country has conducted research on "geometric modeling method" and "building environment construction and its real-time roaming technology", but there is a lack of research on field virtual battlefield environment and virtual driving training. One of the three basic elements ...
