Slice / Clip with Geometry

Hello,
Is there a way to slice or clip a data set using another 3D geometry (e.g. .stl)? The reason I need this: I have a landscape design with varying heights i.e. different levels/ramps/stairs and would like to visualize the wind speed AT EYE LEVEL over the whole topography. To do this, I have modeled a surface (in Rhino) that is an offset from the landscape by the distance needed. I can load this surface as .stl into ParaView and see it nicely intersecting with my data set that is displaying the wind speed. Basically, instead of a clipping PLANE (pic1) I want a clipping SURFACE (pic2). I found this similar question: http://www.cfd-online.com/Forums/ope...ylinder-2.html This was simpler since it was about cutting out a cylinder, and still the solution seemed to be pretty complicated involving scripting. The post is pretty old though and I am hoping there might have been some developments since to facilitate this. I would be grateful for any info pointing me in the right direction! Cheers, Max |

...Anyone??
It would help to know if this is even in principle possible. Cheers, Max |

Hi,
Use the Resample With Dataset filter, selecting your STL as the source. I do not think it allows you to clip without programming, but a slice would be possible. Regards, Tom |

Good day All
I have tried the method outlined above and extracted a slice of the velocity field from model results. However, I note that the slice only maps results from the velocity field to the vertices of the imported STL file which in my case has a limited number of vertices (created the STL using Blender) - which is not terribly useful (or pretty). I am wondering if there is an alternative method to do this that will capture the detail of the actual model results which are at a much finer resolution than the triangulated vertices of the STL file.

As an option, you can always use Remesh modifier in Blender (or any other similar tool) to get more appropriate STL mesh.
