Hi I’m new to VTK.

I am trying to do 3d volume rendering with 2d stacked images.

and what I’m also trying to find out how to visualize the part of it.

for example, If I have ave with an stacked apple picture, I want to get the whole 3d volume object(whole apple) and the one with only seeds.

Is it possible to do things like that with VTK?

Yes, VTK can easily do such data visualization. Your main options are A. image volume rendering, B. image segmentation and surface rendering (you can even use a mix of both). High-level concepts are described in [VTK textbook](https://lorensen.github.io/VTKExamples/site/VTKBook/00Preface/) and there are hundreds of [examples](https://lorensen.github.io/VTKExamples/site/). If you describe what exactly you would like to visualize then you can get advice from domain experts.
