Hi all,
I have a Digital Elevation Model (DEM) in .tiff format. While I am able to load the file into ParaView , it only appears as a flat surface in 3D view, without any relief features. How can I apply vertical exaggeration in the 3D view to better visualize and appreciate the DEM’s relief features?

Hi @kannan
You can use the “WarpByScalar” filter to transform the data.
Best,

That filter is greyed out when i tries to apply to my .tiff file.

Add a `CellDataToPointData` first:

- run ParaView
- File → Open → dem.tiff
- Select “GDal Raster Reader”, Ok
- Filters → CellDataToPointData → Apply
- Filters → WarpByScalars → ScaleFactor: 1e-5 → Apply
Here is a statefile that contains it all:

@mwestphal thanks for detailed reply. i could now able to plot dem in 3D as shown below. but the issue is that if i change the scale factor for increasing Z exagerration, the original data values along Z axis also get altered.
is there any way to the scale Z axis for viewing only without changing data values and tick mark values along that Z axis ?. kind of exagerrating Z values for veiwing purpose.

In the Display properties, look for the “Transform”.

I changed Disply -Transform-scale factor to 4 to exaggerate the view,still the Z value got changed. Pixel value of my DEM (Z/Height) ranges from 1916 to 201 only whereas after scaling value got changed till 8000. Attched screenshot after changing disply values as given below. also aatching stat file.

Properties(WarpByScalar1)- scale factor 1 and normal 0 0 1
Display(StructuredGridRepresentaion)- Transform-Scale-0 0 4

Indeed, you are right, this is unexpected to me, and can arguably be considered a bug imo.
Data Axes grid should also respect the transform.
I’m afraid I dont have a solution at this point, there is no way to show an 3d axes grid with unequal axes in ParaView afaics.
