Abstract
The invention provides an electronic sand table system of a digital city. Based on the computer technology, multimedia technology and large-scale storage technology, the electronic sand table system of the digital city is characterized in that in virtual simulation technology of water effect, through GPU (Graphics Processing Unit) programming technology of the normal mapping, reflection and refraction effect when light is irradiated on a water surface is dynamically processed, so that the water surface can truly reflect an inverted image and the underwater scene; and through the technology of performing octree grid partition on a map and three-dimensional scene model data and performing dynamic compression and decompression at the time of transmission, a three-dimensional scene is quickly displayed. The electronic sand table system of the digital city is applied to city planning, and as a digital virtual system of city status quo planning, the system uses technologies of GIS (Geographic Information System) and the like to give a multi-resolution, multi-scale, multi-space-time and multi-type presentment of the city.
Description
Technical field
The invention belongs to the three dimension system field, be specifically related to a kind of goods electronic sand map system of digital city.
Background technology
Along with digitized extremely speed development, develop a system software, represent the scenes such as various buildingss, vegetation, water system in city truly with the effect digitizing of three-dimensional; Simulate various weather phenomena; And support the loaded and displayed of mass data, and show for the details of buildings, show different building models according to the difference of the current visual range of buildings; And having the performance that the ground that has levels shows fast, is the progressive demand of modernization.
Summary of the invention
The present invention is intended to invent a kind of goods electronic sand map system of digital city, has the loaded and displayed of supporting mass data and has the performance that the ground that has levels shows fast.
For realizing the foregoing invention purpose, the technical scheme that the present invention adopted is:
The goods electronic sand map system of a kind of digital city of the present invention is the basis with computer technology, multimedia technology and extensive memory technology, wherein, and the goods electronic sand map system of said digital city:
To the virtual analog of water effect technology, reflection and the refraction effect during to the water surface carries out dynamic process to the GPU programming technique through the normal pinup picture to irradiate light, makes the water surface reflect inverted image and water-bed scenery truly;
Through map and three-dimensional scene models data are carried out the Octree mesh segmentation, carry out dynamic compression and decompression technique when transmitting, so that three-dimensional scenic shows apace.
Preferably, the frame number of playing up of said three-dimensional scene models per second reaches more than 50 frames.
Preferably; Things in the said three-dimensional scene models simulation reconstruction life comprises buildings, plant, water system, dynamic automobile and aircraft etc., can be according to the setting of time in the system; With simulate day 12 hours by the variation of sunrise to sunset; According to the weather phenomenon of selecting, can simulate the weather phenomenon of rain, snow, mist, fine day truly, show with three-dimensional pattern.
With respect to prior art, the goods electronic sand map system of digital city of the present invention has following beneficial technical effects:
The goods electronic sand map system of digital city of the present invention is applied to city planning, and as the digital virtual system of a city present situation planning, technology such as utilization GIS are carried out the displaying of multiresolution, multiple dimensioned, multi-space and multiple type to the city.
Native system adopts the virtual display technique of computer; Reproduce the scenes such as various buildingss, vegetation, water system in city truly, simulate various weather phenomena, and support the loaded and displayed of mass data; No matter build the thing of building in how many cities of system loads, system can show fast.Show for the details of buildings, show different building models, reach characteristics such as demonstration more has levels, display speed is faster according to the difference of the current visual range of buildings.
