Core of the present invention is UG, Pro/e, SolidWorks; Catia, the Solid3000 model conversation is the D light quantitative model, the D light quantitative model is shown again; Carry out conventional three-dimension varying and annotations and comments, thereby reach the extensive purpose that shows the D light quantitative model on web.
Description of drawings
Fig. 1 is the structural drawing that the present invention shows D light quantized data checker-work;
Fig. 2 is the data file composition structural drawing that the present invention shows D light quantized data checker-work.
Embodiment
Below in conjunction with accompanying drawing the present invention is shown that the embodiment of the device of D light quantized data form is elaborated.
Referring to Fig. 1 and Fig. 2, the present invention shows that the device of D light quantized data form comprises:
Lightweight model conversation device 1, function are with present main flow cad model such as Solidworks, UG, Pro/e, Catia, model conversation D light quantized data forms such as Solid3000;
Lightweight model file treating apparatus 2, function are to open to send out the lightweight model file, read in file header data wherein, file is managed, and corresponding interface is provided, and supply other module invokes;
Lightweight model file resolver 3 cooperates with lightweight model file treating apparatus 2, resolves element figure in the lightweight model file, like products-tree, node, entity, annotations and comments etc.;
Lightweight models show device 4 is used OpenGL and is shown the storehouse, and the D light quantitative model is shown;
Model three-dimension varying device 5 carries out three-dimension varying to the three-dimensional model that shows;
Annotations and comments device 6 adds mark in the component surface specified location, and mark is edited, deleted and revises.
The function of lightweight model conversation device 1 is to transform cad model, generates the lightweight model file.The data layout of present global three-dimensional CAD has hundreds of, but by only tens of kinds of the main flow cad data forms of manufacturing industry application, this device only provides the transformation function of part main flow cad data form; Like solidworks, UG, Pro/e; Catia, Solid3000 etc., the data after the conversion form a lightweight data format file; The data file that generates is as shown in Figure 2, comprises file header, graph data, graphical nodes and products-tree structure.Its basic process is, reading of data from original cad file, and the data that read are formed file through handling.
Lightweight model file treating apparatus 2, its function are to open the lightweight model file, read file header, and reading of data and function interface is provided, by other module invokes.
Lightweight model file resolver 3, its function are on the basis of the data that lightweight model file treating apparatus 2 reads, and resolve the lightweight model, and formation can be used the pel of demonstration, like products-tree, node, pel.
Lightweight models show device 4, its function are to play up the lightweight model.Whole render process comprises selection and draws two steps.In the selection process, system adds the information of playing up of node to the line ordering of going forward side by side in the solid tabulation according to whole model tree of principle traversal of depth-first.System directly travels through this solid tabulation during drafting, calls the function of bottom, realizes playing up of solid.
Model three-dimension varying device 5, the three-dimension varying that supplies a model operation, concrete function has: the demonstration of model geometric data comprises various ways such as painted, wire frame, blanking; The adjustment of observation visual angle comprises translation, rotation, the convergent-divergent at visual angle; With products-tree display model hierarchical information intuitively, can choose the appointment parts through products-tree; The parts attribute is provided with, comprise color, transparent, show and hide etc.;
Annotations and comments device 6, its function are to add mark in the component surface specified location, and mark is edited, deleted and revises.
Solid itself is described with three-dimensional data, though mark is two-dimentional, the position of mark point is with the coordinate coincidence of certain point of solid surface, also is to describe with three-dimensional data.Therefore the seizure calculating of solid and mark need be placed in the three dimensions and carry out.
Basic process of the present invention is with UG, Pro/e, SolidWorks; Catia; The Solid3000 model conversation is the D light quantitative model, the D light quantitative model is shown again, and carries out conventional three-dimension varying and annotations and comments; Thereby reach the extensive purpose that shows the D light quantitative model on web, its core is lightweight model conversation device 1 and lightweight model file resolver 3.The function of lightweight model conversation device 1 is from the CAD source file, to extract raw data.Because cad file is of a great variety, technical difficulty is bigger.The function of lightweight model file resolver 3 is the lightweight data file to be resolved to can be used for data presented.In this process, what of the data volume that resolve to generate directly determine the function of whole device.
In concrete implementation procedure; The lightweight model data file that lightweight model conversation device 1 generates can be a disk file; Be kept in the temporary folder by operating system or application program appointment; As the input data of lightweight model file treating apparatus 2, the lightweight data file that lightweight model conversation device 1 generates also can be a disk file.On network, use this device if desired, then can be placed on original cad file in the service, send to user client by server through network.In lightweight model conversation device 1, transform the cad model file, can adopt ripe Software tool, also can realize through the CAD Software Secondary Development.
Above embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
