As I recently released MB3D 1.98 with point-cloud export, I got some questions about the purpose of those point-clouds.

Point-clouds are similar to solid meshes, but both are simplier and faster to generate and usually have a higher resolution (compared to a solid mesh at the same size), i. e. can contain lots of nice details.

There are multiple programs which allow to render this point-cloud-objects (together with any other meshes) and to create really nice images.

From the artist's point of view, this feature is interesting as you can combine fractals with any other object and may use a PBR (physically based rendering engine) for creating fractal art.

Of course, the number of detail is limited (in comparison to a true fractal renderer), but MB3D 1.98 makes a huge step forward.

Here are some examples, all rendered in Houdini (using the free version):























The maximum volumetric resolution used so far was 3600 x 3600 x 3600 for the last model.

Cheers!

Andreas

Here are some examples, generated with V1.99:

The new flag - use ambient picture as light alsou is pretty good.

 Take some bulb or any other fractal.
- Download some beautifull nebula photo. (not part of M3D)
- Rename it to some short name like Nebula1.jpg.
- In the ligh section - > back pic -> Background image
- Use a small image as ambienty colour. (New in v1.9.cool

Then fractal looks as part of the scenery not of something outside. Well, this could be done manualy but single flag does it mutch faster.
I think space photo are especialy good becouse strange unknown structures of ancient aliens looks better when they are on galactic photos.

Bulbtracer have one additional feature. If your PC is slow enought you get a pretty cool animation in "Trace Preview" going throught the slices of fractal.
It is pretty cool with some formulas and not so with others. Generaly it is symmetrical fractals with holes. But then you must not have very fast PC as speed depends on processor speed. And if it is too fast you don't see animation;)

It reminds Fractal Explorer with some fractal type orbit something.  Julia set of mandelbulb:
