information collection
(1)We need:
a.Master plan
To get the basic terrain, the details such as the road, the river and the surroundings of the whole area, then we can draw out the terrain
b.Divisions (CAD files required)
To get the functions of different areas, such as the living area,CBD, industry area and so on
c. Building Rendering files
To get the construction style and height of the city buildings, and their related surroundings.
d.Show room files(CAD files)
To get the Introduction of the room, the functions of each part, the location of the things in the room, the thickness and the height of the wall , directions of the doors and so on.
f.Show room rendering files
To get the combinations among materials, colors ,styles, and lighting of the room, to get the impression of the room intuitively.
g.Green field plan ,breeds and direction of the trees
To get the green field plan of the city, know about the breeds and location of the trees ,grassplot and playground.
h.Road, street plan
To get the traffic system, travel ways and human traffic plan, vehicle traffic plan, fire control system, to get the road, street plan
i.The pictures of the highlighted part in the city, which show the style ,color of the city
to get the style of the highlighted part, get the main impression of the city,the relationship between drive way, foot path area and the buildings
2. Take Photos of the buildings
a.require the photos of the buildings for texture ( we need to choose the highlighted ones)
b.Take photos of the terrain, road , and bridge
To be used in the 3D modeling software, locate each building models exactly.
3. Sorting the information
Not all the materials will be used in the virtual city projects ,in order to offer the useful information, we have to choose the useful photos and materials , by doing this we can avoid being misleaded by some wrong materials.
4. Modeling
High Detailed Modeling:Detaily modeling include the terrain , traffic system. and CBD, main building and main corporation , the city center must be more detailed, but the buildings farther from the city center can be less detailed (except the especial model that customers consider)
Road modeling : all of the road , bridge and traffic subsidiary facilities, include the land use, the city traffic ,it must reveal the whole plan,
Simple Detailed Modeling : (Assisted Model) Using less detailed modeling to compare the high detailed ones ,present the environment and the whole urban area, appropriately place some models of planning and construction.
Green field modeling : all the trees and the landscape of the city
Animation: shoot animation, car running and persons walk, effects such as water, cloud , fog and so on .
5. Integrate the virtual city with the hardware:
Our virtual city can be combined with many kinds of high technology display systems, such as sphere project systems, multi channel cylinder project systems, CAVE (Cave Automatic Virtual Environment) and so on. it can give you a wide field of vision , as you are touring in the real world.
