Brief description
Fig. 1 is the schematic flow sheet of virtual vehicle sample of railway vehicle matching method provided in an embodiment of the present invention；
Fig. 2 is the structural representation that virtual vehicle sample of railway vehicle provided in an embodiment of the present invention matches system.
Specific embodiment
Fig. 1 is the schematic flow sheet of virtual vehicle sample of railway vehicle matching method provided in an embodiment of the present invention.As Fig. 1 institute
Show, the virtual vehicle sample of railway vehicle matching method that the present embodiment provides, including：
Step 100, calls department pattern, material and/or the color of Virtual Sample Vehicle according to the actual requirements.
Specifically, can be according to user's actual need, department pattern in real-time calling Virtual Sample Vehicle, for example, it is possible to adjust
With different types of headstock model, or different types of material can be called, or call different colours species.
Step 200, changes department pattern, material and/or the color of Virtual Sample Vehicle according to the actual requirements, and sets up new void
Intend sample car.
Specifically, the department pattern of existing Virtual Sample Vehicle can be changed, for example may be used according to demands such as user's design, checkings
To change the models such as car body, drivers' cab or floor, the material of different parts can also be changed, for example, can change seat model
Texture, same way, it is also possible to change the color of different models.
Further, in step 100, call according to the actual requirements Virtual Sample Vehicle department pattern, material and/or color it
Before, also include：
Step 300, sets up model library, Materials Library and the color libraries of rail vehicle.
Specifically, set up the model library of rail vehicle, including：
Step 301 sets up three bit digitizing models of each part of rail vehicle, and presets described three bit digitizing moulds
The assembly relation of type.
3 d modeling software can be passed through（3DMAX, PRO/engineer etc.）Set up three dimensions of each part of rail vehicle
Word model, each three-dimensional digitalization model is all preset with specific assembly relation, to meet three-dimensional digital mould
Type is assembled into the requirement of digital sample car.
Step 302, will be same for function phase in rail vehicle but the different part of structural style is abstract for module and unified mechanical
Interface.
For example, it is possible to define head module, car body module, external door module, roof module, floor module, first-class seat mould
Block, second-class seat modular, side wall module and luggage frame module etc..Each module all includes the different mould of multiple shapes, structure
Type.
Step 303, setting module hierarchical structure it is ensured that model change when all schemes all can mate.To each module
Set the hierarchical structure determining, it is ensured that different model scheme can be mated when changing to the model in same module.
In actual development, can be by the title of module come mark module, the title of module can be program-controlled model
Unique mark, all operations of model can be by realizing to the judgement of model name.The naming rule of module can be：
（Interaction prefix)+(scheme sequence number)+position _ toponym _ sequence number.For example, interaction prefix such as can be beaten for controlling interactive operation
Open or close and close car door etc., scheme sequence number can be easy to procedure identification and differentiation, position _ toponymy as the mark of scheme module
Title _ sequence number can be used for designer to the understanding of model hierarchy structure and differentiation.For example, the portion that all display models can switch
Point, model name is all unified to add (Switch_WK) prefix.All display models will change the part of color, and Material Name is all
Unified addition (SwitchColor_WK) prefix.Inside and outside car door model needs the part that interaction is opened, and model name is all unified to add
Enter (Interact_CM) prefix.All seat models will change the part of texture, and Material Name is all unified to add
(SwitchTexture_Cloth) prefix.All put design seat, model name all unify add (Place_ZY) before
Sew.
Model library is to realize knowledge accumulation, module apolegamy, be distributed the basis rendering raising system real time, and it is by several
By the file composition of module title name, also store one in addition to the model of storage in each file and ordered by module title
The Excel of name（*.xls）Table, records the title of all modules in this table, be stored in the hard disk of server, in file
Model can be carried out uploading, be downloaded and change model or expansion model for designer by network.When need increase module, by network
Model is uploaded in file, and adds the title of new model in Excel table, program is passed through to read the model of Excel table
Title carrys out calling model, realizes the associative operation to module convenient and efficient in systems.
Materials Library is to realize material real-time change, renewal, the basis of newly-increased material, its some by material classification
Textures file forms, and stores the picture of some * .PNG, the material picture in file can pass through net in each file
Network carries out uploading, downloads for designer's modification or expand.When using, system can call the pinup picture in Materials Library to carry out in real time
The switching of material texture.
Color libraries are the bases realizing color real-time change, and it is made up of several txt files, by RGB number in txt file
Word forms, for store and record default color in advance and newly-increased and real-time change after color, when the color lump quilt in colour table
After deletion, in corresponding .txt file, RGB digit groups are removed, the color lump pair of palette in the data in color libraries and system
Should.Color can change in real time in systems, greatly meets the demand to color when scheme makes.
Specifically, step 200, calls department pattern, material and/or the color of Virtual Sample Vehicle to be cut according to the actual requirements
Change and specifically include：The real-time setting of the real-time selection of model, the real-time setting of product colour and/or product material.
Wherein, the real-time selection of described model is specially：Call the model in described model library according to the actual requirements, to void
