Research On The True-3D Volumetric Display Technology

In the research of the simulating train,the game and the entertainment, the 3D images are necessary, but the computer display is the plate screen from which we only can get the dummy 3D images. Meanwhile, the various applications have been used with the technique of the computer graphics theory and the digital image processing. This kind of 3D effect lacks the physical depth and can't support the several viewers'watching the same scene from the several angle of view. Then this dissertation researches a new volumetric display technology- True 3D volumetric display.Firstly, after the voxel attributes are analyzed, a new kind of true-3D file format(TVF) is put forward which can support the translation between the current 3D format and TVF format. This format is verified in the simulation system.Secondly, this dissertation describes the true 3D imaging process after classifying the theory of the true 3D volumetric display system. Then the dead zone of the imaging process is discussed deeply, and the dead zone of the static-swept imaging process is analyzed by mathematics.The main content of this dissertation is about designing the image engine of true 3D volumetric display system. It designs the composing of this engine, and put a new voxel pre-processing arithmetic referring to the ray tracing arithmetic of the 2D display. This arithmetic can reduce the amount of the voxel activation and improve the 3D image display's speed and produce the better true 3D effects.After the voxels are processed by the RVRP mathematics, the activating amounts can decrease and simultaneity the activating order will affect the true 3D effects seriously. Then the dissertation analyzes the activating process, and translates it into the TSP by mathematics, which is the typical NP-Hard problem. To avoid such difficulty, how to get the similar answer is researched. It creates a new method-" Nested Blocking, order optimizing, rotary scanning" and also provides a recursive nested dividing arithmetic(RNDA). This arithmetic can divide the voxel rapidly and effectively by the voxel distributing. Then the calculating size can be reduces quickly.Finally the autostereoscopic display technique's imaging theory and the the N-views combined arithmetic are analyzed which includes two kinds of the display techniques which base on the parallax or the convex. Then by programming a demo system and a simulation system of multi-angles flight onto a kind of autostereoscopic display, some of the researches are verified.The research of this paper commences the field of true 3D volumetric display technology domestically, and provides some theories and ideals for the later research and applications...
