Hi! I’m just getting into Paraview. I’m an Hydraulic Civil Engineer and usually work modeling hydrogeological scenarios. I have a raster-grid with values (Geotif file worked to open in Paraview). This info is also Georeferenced:
- I opened the geotiff in preview.
- Paraview recognize the coordinates correctly
- Paraview recognize the value in each cell correctly (Elevation value) and can show it in a map of colors. Here a picture:
I would like to see this values either as a surface or as a volume (where the top is the surface value). I read some topics that talk about Warp By Scalar or Vector, but when I try to use it from the Filter Menu, it shows not selectable (inactive).
Also I tried a less resolution grid and still does not work
Please any help. Thanks!
To use the warp by scalar you should apply the “Cell Data to Point Data” filter first.
Thanks that worked! here is the same plane now with a Z dimension added.
How I could add volume below that surface? Tried to put “Volume” on the Representation tab
but got this error:
Maybe there is another way? I´m trying to get volume below each cell in the grid as something like this or similar; So I than can do “volume clips” across a section of the volume. Here an example of what im trying
not sure that it will match your expectation, but I would try to apply “Extract Surface” filter, then apply “Linear Extrusion” or “Linear Cell Extrusion”. It should create a volume below your surface.
it’s a big improvement. But when i do a clip within the “volume”, its like an empty box. I used “Linear Extrusion” because “Linear Cell Extrusion” is deactivated maybe that’s the reason. Can´t make it activated
Thanks for your help. And please any suggestions con how to add volume within.
