Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] like figure 1 As shown, the three-dimensional visualization method of virtual crowd movement of the present invention comprises the following steps:

[0046] 1. Preprocessing steps

[0047] The main purpose of the preprocessing step is to generate the template model library, material library, motion database and rendering library required for real-time processing. Therefore, it includes four sub-steps of template model modeling, motion data capture, motion data synthesis, template model and motion data rendering preprocessing.

[0048] Step 10, modeling the template model and establishing a template model library.

[0049] Step 11, analyzing the virtual crowds appearing in the application system, and classifying the individuals among them according to certain standards. For example, according to age and gender, the individuals ...

Abstract

The invention relates to and discloses a three-dimensional visualization method of virtual crowd motion. The method comprises the following steps: analyzing a virtual crowd appearing in a system, classifying individuals, and establishing a template model database and a material database; capturing or manually generating needed human body motion data and inputting the motion data into a motion database; synthesizing the motion data; carrying out drawing pretreatment on the template model and the synthesized motion data; inputting simple script data which describes the crowd motion; generating the virtual individual; driving the motion of the virtual individual; generating the dynamic virtual crowd; realizing group rendering to the virtual crowd. The three-dimensional visualization method of the virtual crowd motion of the invention has the following advantages that: the method is high-efficient and general; modeling cost is low and so on. By using the method of the invention, the virtual crowd motion with a scale of 30000 people can be vividly displayed on a common PC in real time.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a three-dimensional visualization method for virtual crowd movement. Background technique [0002] The visualization of virtual crowd movement refers to displaying the movement data of the crowd on the screen. When the movement data is given to an individual, by observing the movement of the individual on the screen, one can understand the macro or micro effect of the movement data. The three-dimensional visualization of large-scale crowd movement can generate realistic virtual crowds in computer space, and observe the movement of crowds in various places and situations from all angles, which has a very broad application prospect. For example: in the design of large buildings (such as railway stations, stadiums, etc.), designers must consider the performance of large-scale crowds when various emergencies (such as fires, explosions, stampedes, etc.) Visualization technology can co...
