Research About Virtual Scence Simulate Allocating Water Resource In Irrigation And Software Desigen

The engineering irrigation building is one of the irrigation works facilities, play an extremely important role in bringing about an advance in agriculture of our country. Irrigated area is building of engineering irrigation, executor that water resource allocate. Because the irrigated area is big in scale, the compass of competency is wide, personnel have weak technical force, how to show the running situation of the engineering irrigation building real-timely, ocularly, realize the decision foundation allocated in information-based management of irrigated area, engineering construction and water resource.Virtual reality technology is a kind of comprehensive computer figure technology, the latest technology that many kinds of disciplines, such as artificial intelligence, emulation technology, etc. It is formed the fictitious environment of three-dimensional information by computer hardware, software and various kinds of sensors, create one for user and reflect entity's target's change and interactive 3-D view world in real time by way of imitating, in is it perceive lifelike experience of behavior to look at, hear, touch, take a sniff at, participant can explore fictitious target role in environment of living in and change directly, seem to place oneself in the midst of one fictitious world. So, apply to study in irrigated area emulation virtual reality technology and come to display the operation state of the engineering irrigation building through the real-time emulation of the three-dimension, not only has offered the scientific means for the thing that the irrigated area is managed, but also investment is small, so comparatively economic and feasible.This text combines the types and characteristics of the model in the three-dimensional scene of irrigated area, through analyzing that the characteristic of the visual technology of the three-dimension selects every technology used while studying. Describe the different kinds of setting-up course of obtaining the method and model of model data, realize that the visual digital topography of 3-dimension based on DEM date is drawn, adopt source some net spread algorithm calculate rivers flood the area when the change as water level. Study emphatically that operates the data how to organize and manage all kinds of models in real time for the implementation system, state the information mutual way, and the data procedure of implementation system operation is controlled. Put forward the whole frame of a fictitious vision simulation system of simple and easyirrigated area based on a large number of geographical data, to realizing the three-dimensional scene modeling technology and algorithm adopted of irrigated area, and how realization course of the surface feature superposing, real-time emulation, real-time control which carry on the three-dimensional scene is made with detailed exposition. Finally, explain research results and innovation of thesis order, prove actual value to popularize that function has that software realize.
