Description
Technical field
The present invention relates to building cycle information system management technology, more particularly, to the freeway model VR exhibitions based on BIM
Show method.
Background technology
BIM（Building Information Modeling, i.e. BIM, abbreviation BIM）, it is after CAD skills
Art appears in the another important Computer Applied Technology of engineering construction industry, is a kind of building cycle information system management technology, tool
There are simulation, visualization, harmony, optimization property and the big feature of figure five can be gone out.BIM set up three-dimensional digital information technical foundation it
On, it is a kind of brand-new design, construction, management, measure of supervision, BIM contains all stages such as planning, design, construction, operation
Data message.Any stage in any life cycle of building, staff can provide according to model and model
Data are effective, correct decision-making.VR (Virtual Reality, i.e. virtual reality, abbreviation VR), be one kind can create and
The computer simulation system in the experiencing virtual world, it combines computer graphics system, emulation technology, sensor technology, display
A variety of science and technology such as technology, are that the technology for immersing sensation is provided in a kind of three-dimensional environment interacted.
The displaying of highway BIM models is in three-dimensional display software, not set using VR targetedly at present
The software platform of standby displaying.Therefore, shown on current three-dimensional software platform, the observer for being unfamiliar with software operation can not be more
The detailed observation threedimensional model external structure information and model internals attribute information of angle, can not realize it is man-machine between
Interactive operation.
The content of the invention
Present invention aims at a kind of freeway model VR methods of exhibiting based on BIM is provided, observer only needs to band
The upper display helmet, using handle simulator just can with it is on the spot in person observation freeway model information, realize it is man-machine between it is mutual
It is dynamic.
To achieve the above object, the present invention takes following technical proposals：
Freeway model VR methods of exhibiting of the present invention based on BIM, comprises the steps：
The first step, the installation Unity3D platforms in computer, imported into Unity3D platforms, so by SteamVR Plugin plug-in units
Highway BIM models are set in Unity3D platforms afterwards；Be provided with the highway BIM models bridge coordinate position,
Tunnel coordinate position, and the isostructural outward appearance of bridge, tunnel, road and physical dimension data；
Second step, the display helmet, left handle simulator, right handles simulator that are provided with displacement transducer passed through into wireless receiving and dispatching
Module sets up wireless communication connection with the computer；
3rd step, selection key, trigger key are set respectively in the left handle simulator and right handles simulator, and by secondary
Exploitation script realizes that the selection key and trigger key carry out man-machine interaction with the highway BIM models.
Realize that the selection key and trigger key carry out man-machine interaction with the highway BIM models and be in 3rd step：Institute
Stating the selection key of left handle simulator is used to control to change the observation highway BIM model angles, left handle simulator
Trigger key is used for the position for switching view；The selection key of the right handles simulator is used for highway described in controlled observation
The speed and acceleration of BIM models, the trigger key of right handles simulator are used to check highway BIM model built-in attributes.
The invention has the advantages that observer need not be familiar with software, the helmet, the selection of joystick simulator only need to be taken
Key and trigger, highway BIM model informations will show that the viewing that observer can be on the spot in person is at a high speed in the display helmet
Highway BIM model attributes information, highway BIM models are manipulated using handle simulator, form the interaction of people and virtual reality.
Brief description of the drawings
Fig. 1 is the freeway model VR display systems block diagrams constituted according to the inventive method.
Fig. 2 is the workflow diagram of the inventive method.
Embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, the freeway model VR methods of exhibiting of the present invention based on BIM, enters as steps described below
OK：
The first step, the installation Unity3D platforms in computer, imported into Unity3D platforms, so by SteamVR Plugin plug-in units
Highway BIM models are set in Unity3D platforms afterwards；Be provided with the highway BIM models bridge coordinate position,
Tunnel coordinate position, and the isostructural outward appearance of bridge, tunnel, road and physical dimension data；
Second step, the display helmet, left handle simulator, right handles simulator that are provided with displacement transducer passed through into wireless receiving and dispatching
Module sets up wireless communication connection with the computer；
3rd step, selection key, trigger key are set respectively in the left handle simulator and right handles simulator, and by secondary
Develop script（TouchPadPressWalking.cs）Realize the selection key and trigger key and the highway BIM models
Carry out man-machine interaction；The secondary development script write（Touch Pad Press Walking.cs）Function is mainly positioned in advance
Watch path, the selection key of left handle simulator（Upper and lower, left and right key）For controlling to change the observation highway BIM moulds
Type angle, the trigger key of left handle simulator is used for the position for switching view；The selection key of right handles simulator（Upper and lower,
Left-right key）For the speed and acceleration of highway BIM models described in controlled observation, the trigger key of right handles simulator is used
In checking highway BIM model built-in attributes.
When using highway BIM models of the present invention, observer puts on the display helmet, and left hand holds left handle simulator,
