How to? macro images

[jupp2000]

After using XD for years i want to begin with macro-style images of fractals.
But how to render them?
I like the style of Václav Pajkrt's pics, where can i set the depth of field in the render settings of XD?
Or is it necessary to export the mesh and render in a 3rd party 3D software?

Thanks!
