I have a 3d data set and I have created a 3d volume render of the dataset. I want to display the values of the data when I hover the cursor over the 3d volume, but that is not happening. I have observed that "interactive select points " works fine when I use a surface render. So is it possible to make use of "interactive select points " when being in volume render or is there any different ways to do it?
Not possible afaik. You could first convert your dataset into a point cloud, that would let you interactive select through all of it.
@mwestphal Thank you for the response.
I would like to know how do I convert my dataset into point cloud ?
The simplest way (currently) is to use FIndData to select all your points and the ExtractSelection filter.
@mwestphal Thank you. I will look into it.
@mwestphal I executed the steps that were suggested by you. But at the end in order to use the “interactive select points,” I have to represent my cube in the surface rendering. But I want the representation to stay in volume and use the interactive select points.
Here is my representation of my dataset for reference.

Show both the volume and the result of the extraction.
