There are many previous studies related to viscoelastic fluid, however, there are few studies that represent \"spinnability\", which is a feature that the material is stretched thin and long. Although some studies represented thread-forming property, they did not evaluate the stretched length of the material. We also tried to represent spinnability of viscoelastic fluid, however, the simulation results were not similar to a real material. Therefore, we try to perform spinnability simulations with three kinds of models, and evaluate stretched thread lengths by comparison of simulation results with a literature datum.","PeriodicalId":226759,"journal":{"name":"ACM SIGGRAPH 2018 Posters","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128457526","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}

In this work in addition to the existing motion based visual and geometric data processing facilities present in ISSv2, we describe our efforts to incorporate audio processing with the help of Modular Audio Recognition Framework (MARF). The combination of computer vision and audio processing to interpret both music and human motion to create imagery in real time is both artistically interesting and technically challenging. With these additional modules, ISSv2 can help interactive performance authoring that employs visual tracking and signal processing in order to create trackable human-shaped animations in real time. These new modules are incorporated into the Processing software sketchbook and language framework used by ISSv2. We verify the effects of these modules, through live demonstrations which are briefly described.","PeriodicalId":226759,"journal":{"name":"ACM SIGGRAPH 2018 Posters","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121401480","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}

However, it can be quite expensive for animators, game developers and educators on a tight budgets. By using Raspberry Pi Zeros, with NoIR cameras and IR LED light rings, the cost of a four-camera system can potentially be reduced to less than 1000 USD. The research described should lead to an effective and useful system, able to detect multiple markers, record their coordinates, and keep track of them as they move. With a setup of three or more cameras, one would be able to triangulate the data on a low-cost host computer. All software and hardware designs will be disseminated open source, providing anyone who is interested in MoCap, whether it be for hobbyist, semi-professional, or educational purposes, a system for a fraction of the typical cost.","PeriodicalId":226759,"journal":{"name":"ACM SIGGRAPH 2018 Posters","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121336990","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}

Aerial imaging has a strong visual impact, and significant efforts have been made to realize aerial imaging. In recent years, attention has been drawn to optical elements that realize retroreflective transmission, which makes it possible to easily project such images into the air. However, the viewing angle of the aerial image is narrow, and it is difficult for multiple people to simultaneously observe aerial images or to observe aerial images from all angles. Therefore, in the present study, by symmetrically arranging the mirrors at the end of the retroreflective optical transfer system, the maximum viewing angle of the aerial image is enlarged and observation from the entire circumference becomes possible.","PeriodicalId":226759,"journal":{"name":"ACM SIGGRAPH 2018 Posters","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130387896","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}
