<div dir="ltr"><br>Hi all,<br><br>I need to write a threaded application for contours extraction. Namely I have a vtkImadeData and I want to extract several contour surfaces using several vtkContourFilters.<br><br>It returns me an error:<br>
vtkStreamingDemandDrivenPipeline (0xb2b9090): ProcessRequest invoked during another request. Returning failure to algorithm vtkTrivialProducer(0xb2b8d38) for the recursive request<br><br>can somebody tell me what is wrong? Should I apply different filters to different data?<br>
<br>Thanks<br><br>Igal<br><br><br></div>
