Clear presentation. ® 2心's production of the instant virtual reality flow field image of the present invention: the preferred embodiment of the present invention is stored in the computer through the code of the electronic system 1 that carries the display system 1 of the present invention. The hard disk or the computer reads the optical disk, the whole system 1 includes an interconnecting-transfer module 11_, a reading module 12, a collecting module 13, an editing module 14, and : Exhibition: Model 15. The storage device also stores _ pre-made stereo scenes (4) files 22 ‘the file content includes terrain elevation and corresponding stereoscopic model information of the terrain and structure. The generating method comprises the following steps: v private 31 conversion. Since the number of original flow fields generated by the numerical calculation soft disk used to simulate the flow field is 胄2G, it cannot be directly read by the system of the present invention. This requires the conversion of the original flow field data into 2 by the transfer group (1). Flow field data 21 in a readable format of the system 1 is shown. ^: Step 32 - Read the flow field data 21. After the display system i is turned on, the flow field data after the shifting in step 31 is coughed by the Becker, and 22, and the flow field coordinates of the three points in the flow field data are corresponding to the scalar quantity and the vector value. The pure ΐ value refers to the flow field strength of the corresponding coordinates; the vector value includes the flow field strength and direction information. Step 33~ Import the display system 1. The read flow field data 21, together with the stereoscopic scene model file 22, is transferred to the display system 1302675 through the take-up module 13. Step 34~ establish a flow field image 23. Referring to FIG. 3, the editing module 14 uses the coordinates of the stereoscopic scene model file 22 and the flow field data 21 to be positioned, that is, the virtual reality flow field is established in the relative position of the stereo scene model. Image 23. It is worth mentioning that the flow field image established in this embodiment can be expressed as shown in FIG. 4, and the color depth indicates the pure value of the flow field intensity at each coordinate point of a single time point, as shown in FIG. 5 and FIG. 6 . As shown, the flow field vector values of the respective coordinates at a point in time are indicated by arrows, wherein FIG. 5 represents a two-dimensional elevation flow field, and FIG. 6 represents a flow field vector value of each coordinate position of the three-dimensional river channel. Wherein, the direction of each arrow indicates the direction of the flow field at the corresponding coordinate, and the length of the arrow indicates the intensity of the flow field at the corresponding coordinate. Step 35 - Edit the flow field image. The editing module 14 can edit the flow field information through the screen input mode according to the stereoscopic scene and the flow field image established in step 34, as shown in FIG. • Step 36—Show and operate. The display module 15 causes the stereoscopic scene model=the flow field image 23 established in step 34 to be displayed together, and is displayed for zooming, rotating, and wandering through the electric peripherals such as a mouse, a keyboard, and a joystick. Different coordinate position points, real-time virtual reality flow field images of the flow field are observed at different angles. In summary, the method for generating the real-time virtual reality flow field image of the present invention can automatically convert the vector of the numerical simulation software simulation and the scalar flow field data into a virtual reality image, and present a continuous or single time flow field image, or even Observing the various sections and angles of the flow field, regardless of the application in the fluid mechanics 1302675 teaching or hydraulic engineering planning and design presentation, can more realistically present the flow field conditions, and indeed achieve the purpose of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change and modification made by the patent application scope and the description of the invention. All remain within the scope of the invention patent.
