Computer Three-dimensional rep

In real-life of today, computer show dynamic and mutual for buildings is often necessary using virtual reality.
Establishing virtual reality has a large choice of methods, but the differences of effects are big. A best technology is got by study in the paper, it is very convenient and agility.
Key words： Virtual reality; multi-dimension material; three dimension; Boolean operation In the real life of today, it’s often necessary to computerize the building view especially at the time of making policy, tendering and selling the building. To realize dynamic show and mutual observation, it is a must reproducing the building three dimensionally through computer.
Reproducing buildings in three dimensions is a hot topic at present. To establish virtual reality there are a large number of methods, which differ in the convenience and flexibility to provide dynamic show and mutual observation. Through many years of research and continuous experiments we have acquired the advanced technology to achieve dynamic show and mutual observation in the most convenient and flexible way.
This technology comprehensively applies such tools as AutoCAD, 3DSMAX and Photoshop. If the building has been built, it is necessary to take pictures of the building at-the-spot from various angles and then process (cut, restore, and adjust clairvoyance)by photo processing soft wares. This paper is centered on the key of computer three dimensions establishing technology-the technology of processing through 3DSMAX.
There are 5 steps in using 3DSMAX:
(1) Establish multi-material
(2) Establish the model and fill in material
(3) Appoint ID to the building model and distribute material to each ID
(4) Adjust painting.
(5) Moving picture making.
