Unfortunately after hiding the cube Blender crashed when I selected the bulb.

Uhhh...how do you hide the cube?

I usually just select it and press delete.

My guess is that this is pure Mandelbulb3D.
Really?  That is possible right in MB3D?
How?

Good question, let's wait for Jesse's answer, who knows, the man is full of resources! As he mentioned that he was limited by the 6 formula tabs, I thought he did it entirely in M3D. For sure he would have used the DE Comb Min mode to combinate the bulb with the rest (5 tabs left to make the ground and the animal using a strange hybrid). But after a second thought, that seems difficult, because to make the bulb bounce he would have had to use the _Translate formula as a pre-transform, and unfortunately it's not possible to combine 2+4 hybrid formulas, only 1+5.

Yep, well examined.  It is actually not the bulb that translates, but the whole IFS thingy + the camera with it  smiley

Will make these dIFS formulas available in the next (beta?), have first to change them to get also correct inside DE's so that inside rendering (and maybe transparency sometime) will be fast as outside for these formulas.


*add: dIFS are more like iterated primitives, dunno a better name for it (d for direct DE)

Yeah, it's better to delete it but if you want to only hide it, then just click on the eye icon for the cube in the scene hierarchy tree on the top right of the interface.

I thought about that, but it's so difficult to make accurate camera moves. How did you do that, by inputting directly Y mid value in the main window? If so, how did you manage to keep the same angle of view?

Never heard of Kerkythea!

Another one to try   nasty teeth

Kerky is very cool and addictive, here is a quick (and not too good) render of your bulb (or is it the cow?) made in it using (fractal?) procedural plugins for coloring and bump.

Yep, just changing the Mid-value, i guess it was Z, so i changed the Zstart and Zend values also the same offset.
The camera angle is not changed this way, no need for further adjustments.

That's very clever, but coming from you, not that a surprise! I can't wait to play with your new dIFS stuff cheesy

I generated a 600x600x600 voxel stack and decimated the resulting object in Vue 10 Infinite. So I got more details but have just about the same filesize as a 400x400x400 object. I put it in one of my Vue scenes and renamed the scene to "There's a Mandelbulb in my Garden".  laugh

You really can't wait because i already uploaded the update  wink

It is probably not that much to play with, formula restrictions and so.  And i have to make some better transformations maybe...

Nice garden, Teena!
I included 2 sample shrubs in the current update, maybe something you can plant.  cheesy

Thanks for your nice words and even more for Mandelbulb3D. You did a super job and it's so much fun to play with it.

I'll download the update in a minute and see how your shrubs grow in my garden.  grin

How would this thing look like when you change the material to glass or crystal? Also maybe making it float in water could look nice.

As you could read my mind, stranger  wink
..because i already send the shrubs to holy land in overseas... no need to imigrate them in the garden anymore (i know what a mess voxelexport can be  laugh)

Not quite that but almost, here is another quick and dirty Kerky experiment, 256 bulbs instantiated onto a glass sphere floating in the sky.

Thanks, that's limited because it's not possible to make hybrids with regular formulas, but it's already good fun to play with, M3D is becoming such a versatile program now! I have to study your examples to understand more precisely how it works, but it seems extremely promising. And I like the HeightMap too (see attachment)

no need to imigrate them in the garden anymore (i know what a mess voxelexport can be  laugh)


Back to this thread's topic, voxel export is still needed to make real 3D prints, but Fiji seems to be doing the job. Anyway, with the new dIFS function, this is giving M3D a new set of infinite possibilities (Incendia-like fractals I guess). What a great program!

These are some cool scenes, guys. Very imaginative!

Here is my image "Julia Approaching for Rescue" textured and rendered in Vue 10 Infinite:



I used a picture on the Julia fractal and made it 50% transparent. I used a light glass material on the mandelbulb.
