Method for 3D Rendering Based on Intersection Image Display Which Allows Representation of Internal

Method for 3D rendering based on intersection image display which allows representation of internal structure is proposed. The proposed method is essentially different from the conventional volume rendering based on solid model which allows representation of just surface of the 3D objects. By using afterimage, internal structure can be displayed through exchanging the intersection images with internal structure for the proposed method. Through experiments with CT scan images, the proposed method is validated. Also one of other applicable areas of the proposed for design of 3D pattern of Large Scale Integrated Circuit: LSI is introduced. Layered patterns of LSI can be displayed and switched by using human eyes only. It is confirmed that the time required for displaying layer pattern and switching the pattern to the other layer by using human eyes only is much faster than that using hands and fingers. Computer input by human eyes only is proposed and implemented (1)-(3) together with its application to many fields, communication aids, electric wheel chair controls, having meal aids, information collection aids (phoning, search engine, watching TV, listening to radio, e-book/e-comic/e- learning/,etc., domestic helper robotics and so on (4)-(15). In particular, the proposed computer input system by human eyes only does work like keyboard as well as mouse. Therefore, not only key-in operations but also mouse operations (right and left button click, drag and drop, single and double click) are available for the proposed system. It is well known that hands, fingers operation is much slower than line of sight vector movements. It is also known that accidental blink is done within 0.3 second. Therefore, the proposed computer input system by human eyes only decides the specified key or location when the line of vector is fixed at the certain position of computer display for more than 0.3 second. In other words, the system can update the key or the location every 0.3 second. It is fast enough for most of all application fields. Meanwhile, 3D image display and manipulation can be done with 3D display. Attempts are also done with 2D display for 3D image display and manipulation, on the other hands. Most of previous attempts are based on touch panel based manipulation by hands and fingers. As aforementioned, eyes operations are much faster than hands & fingers operations. Therefore, 3D image display and manipulation method by human eyes only is proposed in this paper. The proposed method is essentially different from the conventional volume rendering based on solid model which allows representation of just surface of the 3D objects. By using afterimage, internal structure can be displayed through exchanging the intersection images with internal structure for the proposed method. Through experiments with CT scan images, the proposed method is validated. Also one of other applicable areas of the proposed for design of 3D pattern of Large Scale Integrated Circuit: LSI is introduced. Layered patterns of LSI can be displayed and switched by using human eyes only. It is confirmed that the time required for displaying layer pattern and switching the pattern to the other layer by using human eyes only is much faster than that using hands and fingers.
