Our package generates a loadable Simulink module for each VTK class, which is then represented as a “block” on the Simulink canvas, and can be connected with other blocks to form a pipeline. Each block can be double-clicked to bring up a dialog box that allows introspection and control of the VTK class. After a VTK pipeline has been built, it can be run interactively from within Simulink. The outputs of the pipeline can be displayed in an interactive render window, written to a disk file, or exported to a MATLAB variable. Within Simulink, the VTK pipeline can also be connected to the ITK pipeline through the use of our SimITK package. We generate the VTK-Simulink wrapper automatically though the use of CMake build scripts, with XML as an intermediate representation of the VTK class interfaces.","PeriodicalId":251524,"journal":{"name":"The VTK Journal","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121183186","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}
