3D Holographic Rendering For Medical Images Using Manipulates Lighting in a 3D Pyramid Display

Abstract

3D data visualization and 3D display have received extensive attention from researchers due to the rapid growth in computer graphics in the human’s daily life. Despite the massive studies efforts consumed for 3D visualization, the shape perception of a 3D model has not yet been satisfied. In this study, we enhanced the visualization of 3D data for a hologram pyramid display by proposing a procedure named the hololighting style which consists of two steps. The first step is enhancing the shape perception of the 3D data. We proposed a new lighting system to emphasize the shape feature by employing non-photorealistic rendering as an alternative to the traditional lighting. The second step in the procedure is 3D hologram rendering for the hologram pyramid display. The screen is split in this step into nine segments for creating four viewports to contain 3D object from four views which are front, back, left and right. These steps are created and implemented using Visual C++, OpenGL 4.5. The results showed the enhancement of the 3D data as a hologram floating inside a transparent pyramid. The quality of the hologram is reported to be preferred when compared to a traditional 2D display. Moreover, the shape of the 3D data was reported to be enhanced by the new lighting style when compared to traditional lighting
