Default 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,

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
