Description
Technical field
The invention belongs to 3D models to print field, more particularly to a kind of teleengineering support communication method based on 3D models.
Background technology
Current most of product can not almost support the teleengineering support based on 3D models based on mobile terminal and PC ends to link up
Function, only a few provide the traditional communication way of remote transmission word, so caused in 3D design processes, designer and use
Family can not effectively be linked up and carry out results verification, and then the finished product rework rate printed is higher, causes bigger
The wasting of resources.
The content of the invention
In view of the drawbacks described above of prior art, it is more square that the technical problems to be solved by the invention are to provide a kind of use
Just the teleengineering support communication method based on 3D models.
To achieve the above object, the invention provides a kind of teleengineering support communication method based on 3D models, its feature to exist
Performed according to the following steps：
Step 1: upload and parse 3D model meshes data；
3D model meshes data files are uploaded, the position in split point and face and numbering forms mid files after being parsed,
And it is encrypted；
Link is linked up Step 2: establishing；
This process employs WebRTC Floor layer Technology, is caught using websocket protocol by front end javascript
Setting and the URL information of user is obtained, stun/turn intermediate servers are transmitted by https agreement, when stun/turn confirms
All terminals for participating in linking up all have been switched on linking, after the certification for obtaining ssl, side that stun/turn passes through three-way handshake
Formula establishes stable link；Mouse track information is synchronized by server.
Further, the step of in addition to being marked；
Mark, which is utilized on the mesh that three.js is established, redraws continuous point, then the operation merged, and
Based on the resolution ratio of user's local computing, dynamic adjusts the fineness of mark line.
Further, the step of in addition to preserving interim and permanet mold；
It is the whole scene for automatically saving three.js during preservation, and employs canvas automatic sectional drawing technology,
Scene results are preserved by https+websocket host-host protocol.
Preferably, the 3D model meshes data file, one kind in form stl, off, obj.
Preferably, the step 1 mid files is encrypted using binary AES based on SHA.
Preferably, being transmitted when the step 1 uploads 3D model meshes data files using https checking, entirely render
Process use WebGL rendering engine, while done downsampling algorithm process.
Above technical scheme user different 3D file formats can be imported to the conversion for carrying out unified form and encryption is led
Go out, whenever can check online, real time remote is shared to link up.First by parsing the 3D file formats such as stl, off, obj,
The position in split point and face and numbering mid afterwards, and binary AES based on SHA has been carried out, mid files are any
When can be opened by Photographing On-line software, in upload procedure using https checking transmit, ensure transmitting procedure in number
According to that can not be intercepted, the process entirely rendered uses WebGL rendering engine, while has done at downsampling algorithm
Reason.
Real time remote communication is established in this programme, https ssl certifications are passed through by intermediate server and Platform Server
Mode three-way handshake establish the link, point-to-point communication can be carried out afterwards, only pass through the mouse track information of user
Server transport, the bandwidth consumption of server is so greatly reduced, ensures the quality linked up, and webRTC+socket
Technology is cross-platform, so supporting the browser (chrome, firefox, IE) of various main flows on mobile terminal or PC.
This programme according to Jjavascript seizure coordinate make marks on 3D grid datas with Bezier method, enters one
Step improves the validity of communication and ensure that the uniformity for linking up information.In addition, user create every time communication link be all with
Machine generation, the different communication requirements of user are so also met, avoid influenceing.
Preferably, the mouse track information mousedown by javascript technologies, mousemove and
The cavas members that mouse event in mouseover is tied to html usually obtain.
The beneficial effects of the invention are as follows：Operating process of the present invention is simple, and can realize that user is based on movement real-time stabilization
The online 3D at end and PC ends designs and real-time communication, realize the demand of fast integrationization printing, and improve Consumer's Experience.
Brief description of the drawings
Fig. 1 is the principle schematic of the embodiment of the invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of teleengineering support communication method based on 3D models, is performed according to the following steps：
Step 1: upload and parse 3D model meshes data；
3D model meshes data files are uploaded, it is general to form platform for the position in split point and face and numbering after being parsed
Mid files, and it is encrypted, mid files can be opened by Photographing On-line software at any time.
Link is linked up Step 2: establishing；
User then establishes communication link by sharing and sending link when the personnel for participating in linking up access link,
Enabled when user is establishing the link and open the link of audio frequency and video resume if audio frequency and video are set immediately, this process uses
WebRTC Floor layer Technology, utilizes that websocket protocol captures the setting of user by front end javascript and URL believes
Breath, stun/turn intermediate servers are transmitted by https agreement, when stun/turn confirms all terminals for participating in linking up
Have been switched on linking, after the certification for obtaining ssl, stun/turn establishes stable link by way of three-way handshake；This mistake
Three-way handshake establishes the link by way of intermediate server carries out https ssl certifications in journey, can carry out afterwards point-to-point
Communication, only user is synchronized by server to mouse track information；, avoid the operation knot of whole 3D models
Fruit is transmitted to server with 2D or 3D pattern, is so greatly reduced the bandwidth consumption of server, in addition, user creates every time
Found a capital and link up what link was randomly generated, so also meet the different communication requirements of user, avoid influenceing.
The step of the present embodiment also includes being marked；User during real-time communication to model by doing corresponding mark
Note, has reached more preferable communication effectiveness.Mark, which is utilized on the mesh that three.js is established, redraws continuous point, then carries out
Merge operation, and adjust the fineness of mark line based on the resolution ratio of user's local computing, dynamic, make Consumer's Experience
More preferably.
The step of the present embodiment also includes preserving interim and permanet mold；
User preserves newest record and preserves permanent model record manually, checks and link up whenever and wherever possible newest mould
Type.It is the whole scene for automatically saving three.js during preservation, and employs canvas automatic sectional drawing technology, passes through
Https+websocket host-host protocol preserves scene results.
3D model meshes data file described in the present embodiment, one kind in form stl, off, obj.The step 1 pair
Mid files are encrypted using binary AES based on SHA.Step 1 described in the present embodiment uploads 3D model nets
Transmitted during lattice data file using https checking, the process entirely rendered uses WebGL rendering engine, while does
Downsampling algorithm process.
The present embodiment mouse track information by the mousedown of javascript technologies, mousemove and
The cavas members that mouse event in mouseover is tied to html usually obtain.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
