Fig. 2 shows the schematic diagram of three-dimensional display monitoring system of the present invention.
Embodiment
Before the explanation execution mode, introduce the several notions in the graphics earlier:
1, OpenGL (open graphic package interface);
OpenGL (open graphic package interface) is at SGI, SUN, Microsoft, DEC is under the advocating of the famous Computer Companies in the Duo Jia world such as IBM and Intel, a kind of 3-D graphic routine interface of associating release, it can be integrated into UNIX, and the above version of Windows95 is in the window systems such as above version of WindowsNT3.51 and Xwindow, be a kind of and hardware, a series of API (application programming interfaces) that window system and operating system are relatively independent.It comprises more than 120 graph function, and the developer can utilize these functions to draw out three-dimensional scence true to nature, and the benefit of its maximum is stable performance, can cross-platformly use, and has good transplantability.Because OpenGL is the bottom shape library of 3D figure, the geometry entity pel is not provided, can not be directly in order to describe scene, still, by some conversion programs, the model file that can easily some 3D graphic design softwares be made converts the summit array of OpenGL to and uses for it.At present at CAD/CAM, virtual reality, military affairs, space flight, fields such as geological prospecting have obtained using widely.
2,3DS file;
The 3DS file is the graphic file under the 3DMAX software, in showing, often be used to (it is read) based on the OpenGL 3-D graphic, the 3DS file is formed (inlaying sub-piece in the bulk) by many (chunk), a piece is made up of block message and blocks of data, block message is again by the ID (sign of two byte longs of piece, as 4D4D) and the length of piece (four bytes, in fact just the offset word joint number of next piece) form.Each piece is a hierarchical structure, when therefore each in reading the 3ds file led " piece " and son " piece " thereof, obtain corresponding data message according to corresponding son " piece " ID, thereby finally obtain the data such as apex coordinate, texture coordinate, normal vector coordinate, illumination information, material of device model file.

104. be converted into OpenGL summit array.
The data message of the 3DS formating equipment model file in the read step 102 also is translated into OpenGL summit array.When realizing this step, need set up one and set up Mathematical Modeling (programmed algorithm), Mathematical Modeling reads the data message of 3DS formating equipment model file and is translated into OpenGL summit array, and the data message of the GDS formating equipment model file that reads comprises the data messages such as apex coordinate, texture coordinate, normal vector coordinate, illumination and material of device model.
106. create the OpenGL display list of device model.
Form the OpenGL display list that construction is equipped with model according to the OpenGL number of vertex, so-called OpenGL display list be exactly one group of preliminary election store wait until after the function statement called, when calling this display list with regard to in-order execution function wherein, and cooperate the OpenGL graphical display function that calls to show, just reached the effect of relevant device models show.
108. realize the matrixing of device model, move with the driving arrangement model.
Create the transformation matrix of device model, this transformation matrix comprises the transformation matrix of each parts of equipment integral transformation matrix and the different actions of needs realization, transmit the exercise data of the equipment that comes in real time according to the Programmable Logic Controller (PLC) of pier facilities, the equipment scheduling control system of harbour is shone upon the device model coordinate that is converted in the simulated environment with the absolute coordinate of equipment in actual environment, the action that is about to equipment in the stockyard is converted to the action of equipment in the simulated environment in real time, carry out the matrixing of relevant device model according to OpenGL matrixing function again, because each transformation matrix has all been represented the action of a class, so and then driven device model and move.
On the other hand, the invention provides a kind of three-dimensional display monitoring system 200 of pier facilities, referring to Fig. 2:
Database 20 is in order to the storage associated data files;
Converting unit 10 is connected with described database 20 and pier facilities 40 respectively, and the real-time 3DMAX device model file of generated code head apparatus 40 also is converted into 3DS formating equipment model file by three-dimensional graphics software and is stored in the described database 20;
Display monitoring unit 30, be connected with described database 20, read the data message of 3DS formating equipment model file and be translated into OpenGL summit array, create the OpenGL display list of device model, and the transformation matrix (comprising the transformation matrix of each parts that can realize different actions in the equipment) of creating device model, according to the matrixing of OpenGL matrixing function realization device model, the driving arrangement model is made corresponding actions.
The data message of the 3DS formating equipment model file that described display monitoring unit 30 reads comprises apex coordinate, texture coordinate, normal vector coordinate, illumination and material model data information.
The operation principle of the concrete workflow of the three-dimensional display monitoring system 200 of a kind of pier facilities provided by the invention and the three-dimensional display method for supervising 100 of pier facilities is identical with idiographic flow or similar, so do not repeat them here.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop on claim scope of the present invention to variation, the modification of the above embodiment.
