The framework is able to remove the background noise inherent in time-of-flight cameras, detect multiple people, and track up to 30 joints of free motion for each person. The approach has several advantages over traditional motion capture, as it is a cheap alternative to magnetic and optical systems, and requires no markers whatsoever. Unlike markerless systems based on RGB cameras [Duetscher et al. 2000; Kehl and Van Gool 2006], our framework yields dependable results at an interactive rate using a single camera.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128674592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gračanin","doi":"10.1145/1666778.1666820","DOIUrl":"https://doi.org/10.1145/1666778.1666820","url":null,"abstract":"With large scientific and medical datasets, visualization tools have trouble maintaining a high enough frame-rate to remain interactive. In this paper, we present a novel GPU based system that permits visualization of isosurfaces in large data sets in real time. In particular, we present a novel use of a depth buffer to speed up the operation of rotating around a volume data set. As the user rotates the viewpoint around the 3D volume data, there is much coherence between depth buffers from two sequential renderings. We utilize this coherence in our novel <i>prediction buffer</i> approach, and achieve a marked increase in speed during rotation. The authors of [Klein et al. 2005] used a depth buffer based approach, but they did not alter their traversal based on the prediction value. Our prediction buffer is a 2D array in which we store a single floating point value for each pixel. If a particular pixel <i>p</i><sub><i>ij</i></sub> has some positive depth value <i>d</i><sub><i>ij</i></sub>, this indicates that the ray <i>R</i><sub><i>ij</i></sub>, which was cast through <i>p</i><sub><i>ij</i></sub> on the previous render, intersected an isosurface at depth <i>d</i><sub><i>ij</i></sub>. The prediction buffer also handles three special cases. When the ray <i>R</i><sub><i>ij</i></sub> misses the isosurface, but hits the bounding box containing the volume data, we store a negative flag value, <i>d</i><sub><i>hitBoxMissSurf</i></sub> in <i>p</i><sub><i>ij</i></sub>. When <i>R</i><sub><i>ij</i></sub> misses the bounding box, we store the value <i>d</i><sub><i>missBox</i></sub>. Lastly, when we have no prediction stored in the buffer, we store the value <i>d</i><sub><i>noInfo</i></sub>.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122223320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Set in a large open-air hangar, the story takes place among several great aircraft from aviation history. An experienced professional with many years of experience, the pilot's confident and normally reserved disposition quickly gives way to a display of youthful exuberance. As each part of the engine is described, he becomes more lost in a world of admiration and amazement for such items as \"combustionators\" and \"turbinators.\" The captain's growing enthusiasm for the subject matter is evident in both his dialog and his impassioned gestures. When the captain finally concludes his description of the highly technical device, his audience is revealed to the viewer in a humorous twist, which leaves the enigmatic pilot at a loss for words.","PeriodicalId":180587,"journal":{"name":"ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124884678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the developed system, user can lessen their efforts and laborious time on shading process by slightly tuning some attributes of those shaders even though CG artists have not a sufficient knowledge of shader attributes.
