How to realistically display particles of two different radii

Hello researchers, my VTK file contains two types of particles with different radii. However, during the visualization process, I found that different particles have different colors but the same size. I want to display different radii. How should I proceed? If this problem is solved, I would be extremely grateful.

Are you using PointGaussian ? 3D Glyphs representation ? Glyph filter ?

No. I saw it online, and I want to implement the function shown in the picture, but I don’t know how to operate it.

Here it is:

  • open your files, Apply
  • Filters → Glyph
  • GlyphType → Sphere
  • Scale Array → Radius
  • Apply

Thank you!
