Hi everybody,<br><br>I'm working on a CFD project and want to port existing visualization routines to the amazing VTK. It took me quite a lot time to figure out how to plot scalar fields and to set up offscreen batch rendering. I now try to implement some more advanced features and do not want to waste too much time in a one way road.
<br><br>Currently I'm using a TCL script to plot vector fields from an unstructured grid and acquired nice results. Value blanking is no problem when using vtkTreshold, but using vtkBlankStructuredGrid seems to be impossible with that kind of data (I want to use another field that indicates blanking by ones and zeros). Same thing for vtkStreamLine: I read somewhere that a structured grid is necessary. Are there any equivalent functions for unstructured grids, or a routine that maps the unstructured data to structured (don't think so!)? I probably need to use the unstructured instead of a structured grid, because we are computing CELL_DATA which seems to be possible in an unstructured grid only.
<br><br>I'm willing to write a tutorial on this afterwards since it took myself really long to find the basic stuff. <br><br>I spend already a lot of time on this and appreciate any help<br>many thanks in advance<br>
