Problems solved by technology

Obviously, when the described scene becomes complex, due to the extremely large number of entities and their parts and the complicated connection methods, this traditional scene description method greatly increases the complexity of building and updating the 3D virtual model and reduces the model processing. The speed makes it impossible to guarantee the effect of simulation and real-time requirements at the same time under the existing computing resources

Embodiment Construction

[0026] Below we refer to the accompanying drawings to describe the embodiments of the present invention in detail.

[0027] As shown in Figure 1, Fig. 1 has provided the block diagram of computer system structure according to the present invention, and this computer system comprises central processing unit (CPU), internal memory, external memory, system bus scene database file, graphic accelerator card, display, standard graphics Library (such as OpenGL), scene initialization unit, scene drawing unit, scene updating unit. The operation of the system shown in Fig. 1 is divided into two stages: scene modeling (0202) and real-time simulation (0203). Next, the scene modeling and real-time simulation run by the system are described in detail.

[0028] Fig. 2 shows the main flow chart of the 3D scene dynamic modeling and real-time simulation performed by the system shown in Fig. 1 . In step 0204, the CPU establishes a virtual scene model; in step 0205, the scene initialization uni...

Abstract

This invention relates to a system and method of three-dimensional scene dynamic model and real-time simulation. It includes: CPU constitute the suppositional scene model; scene initialization unit, data library paper to introduce suppositional scene, protract unit of scene to introduce scene connection image and initialize the three-dimensional model; the scene update unit updates the scene protracted by protract unit, and re-protract it. This method includes: A. build suppositional scene model; B. introduce suppositional data library paper; C. from connection scene picture; D. initialize the three-dimensional scene; E. protract three-dimensional scene; F. update the scene; G. re-protract this scene.

Description

technical field [0001] The invention relates to the technical field of virtual reality and visual graphics processing, in particular to a system and method for dynamic modeling and real-time simulation of a virtual three-dimensional scene. The system and method can be used in the production of 3D animation and the application of visual real-time simulation of virtual scenes to describe and model entities in 3D scenes, update the positions and state changes of entities in real time, and update the virtual The scene is displayed on an output device (monitor, printer, etc.). Background technique [0002] Virtual reality technology (Virtual Reality), also known as spirit world technology, is an advanced human-computer interaction technology that uses computers to simulate human behaviors such as seeing, hearing, and moving in a natural environment. The characteristic of this technology is that the computer produces an artificial virtual environment, which is a three-dimensional...
