Preprocessing Of3D Model For Volumetric3D Display

In the real world, True3D Volumetric Display technology displays a virtual3D image having the real physical depth of field.Foreign True3D Volumetric Display technology research in the basic theory and key technologies has gotten a lot of results; there have been several True3D Volumetric Display device designs and related applications. In the domestic, research is mainly concentrated in the introduction and improvement of the theoretical research and the various foreign True3D Volumetric Display devices. However, the development of the software process is lagging behind the development of the hardware design. On the software side, the problem of data processing and optimization, how to improve the friendliness of human-computer interaction, and how to improve the data structures’compatibility of a variety of file formats, lack of specialized research. Response to this phenomenon, on the basis of the study of the slice image generation method, several3D model data preprocessing methods for slice data are presented. These methods are better able to optimize the slice data generation process, to improve the stereo image effects, and improve the efficiency of data generation. In this paper, the following issues are researched and resolved:Firstly, the slice image data used for True3D Volumetric Display device comes from the processing3D model data, which is from a variety of3D modeling software, or3D model reconstruction software. Their file format is complex, and has heterogeneous and diverse data structures. In order to resolve how to read a variety of3D model file format, this paper proposes a method to solve a problem how to consolidate a variety of heterogeneous information into an abstract data structure, and provide some uniform methods of operation for it. This method improves on the data structures compatibility of a variety of3D model file formats.Secondly, in order to generate the slice image, the model data from the reading3D model file is seen as a monomer, whose position need to be configured. In addition, model data could be read several times from the same or a different file as multiple monomers. And then you need to deal with the logic control and the control of mutual positional relationship between multiple monomers. Therefore, this paper proposes a manipulation method of the single model and the multi-model. This method has advantages to enhance the friendliness of human-computer interaction, optimize the orientation configuration of the model, and ultimately improve the quality of slice images generated.Thirdly, in the industrial design, often need to display the internal structure or material of the products’design. In this paper, a function which could endoscope the3D model was studied, and incorporated into the generation of slice images. Its effect could be demonstrated in the true3D imaging. The design of Model Endoscope provides a more diverse choice for True3D Volumetric Image Display.Finally, this paper designed and developed a software program which could pre-process the3D model data for True3D Volumetric Display device. The main function of the software are:the reading and rendering of the several formats’3D model file, the model manipulation, the model endoscopic, the generation of slice images and the visual simulation of the corresponding functions.
