A Fast Rendering Method for Water Droplets on Glass Surfaces
Shuichi Takenaka,Yoshiki Mizukami,Katsumi Tadamura 대한전자공학회 2008 ITC-CSCC :International Technical Conference on Ci Vol.2008 No.7
This study proposes a fast rendering method for water droplets on glass surfaces, where the merger phenomenon between two droplets at non-adjacent cells is represented by detecting the collision of their contours and moving them closer into a single water droplet after the collision detection. The appearance of water droplets is efficiently rendered with an environmental mapping technique, a generating method of texture images using the framebuffer object function, and plotting these images using the point sprite function.

Wahrend ich diesen Uberblick schrieb, habe ich mich gefragt: Wozu Deutsche Geschichte durch japanische Historiker? Ich habe nach Grunden fur die Schwierigkeiten gesucht. Es ist mir dann langsam klar geworden, dass es keinen grundlegenden Konsens fur die Aufgabe japanischer Deutschlandhistoriker gibt. Man hat zwar einen Themenkatalog, es fehlt aber die Synthetik der Geschichte (beziehungsweise die Synthetik der Geschichtsforschung). Diese Tendenz wird immer starker, weil einzelne Arbeiten immer praziser werden, mit anderem Worten: viele Arbeiten konzentrieren sich auf Randphanomene. Aber was erwarten die Kollegen in Deutschland von uns? Wie kann man die Interessen an Geschichtsforschung mit ihnen teilen? Wie bereits erwahnt wurde, ist ein Anknupfungspunkt die Arbeit zu den deutsch-japanischen Beziehungen. Und diese Methode und These kann man in einem breiteren Kontext auch fur die Erforschung der deutsch-ostasiatischen Beziehungen verwenden.

Purpose: To investigate the feasibility and optimal port placements of robot-assisted laparoscopic nephroureterectomy (RANU) via the retroperitoneal approach in the lateral decubitus and supine positions using the da Vinci Xi (DVXi) and da Vinci SP (DVSP) systems. Materials and Methods: We performed lateral decubitus extraperitoneal RANU on the right side and supine extraperitoneal RANU on the left side using the DVXi and DVSP systems without repositioning in two fresh cadavers. In addition, paracaval and pelvic lymphadenectomies were performed simultaneously during both surgical procedures. The operative time of each procedure was calculated, and the technical details associated with these procedures were evaluated. Results: Lateral decubitus and supine extraperitoneal RANU using the DVXi and DVSP systems were achieved without repositioning. The surgeon console time ranged from 89 to 178 minutes, and no major technical complications were observed. However, carbon dioxide insufflation into the abdominal cavity was observed owing to a peritoneal breach during the creation of the surgical workspace, particularly in the supine position. Compared with the DVXi system, the DVSP system was more suitable for RANU using the retroperitoneal approach, except for renal handling. Conclusions: The DVXi and DVSP systems are feasible for performing lateral decubitus and supine extraperitoneal RANU without patient repositioning. The lateral decubitus position may be better than the supine position, and the DVSP system is more suitable for retroperitoneal RANU than the DVXi system. Nevertheless, further studies should be performed in clinical settings to validate our results.
