A while ago i played around with some blobs ... and this, though not much more
than a better test-render, is the result. :)

For those that want to know how it's done: I used a spline to control the
probability to drop a sphere at some random point (depending on the horizontal
distance from the origin). The radii of the spheres are controlled the same way
between the minimal and maximal radius.
The first sphere is dropped on a plane with trace() and then added to a union of
the plane (and other spheres), and the coordinates and radius are saved into an
array. Then the next sphere is dropped, and so on... (More or less the same as
i=i+1. Only with spheres in a union and some abort conditions.)
Then the coordinates and radii are used for the components of a blob.

The only other things here are a point light with photons and a white plane.
Unfortunately i couldn't increase the quality of the photons, as my RAM was
full.


I hope you like it. :)

I like it!

It looks like there's a face or skull right about in the center.

I quite like the image as well.  Thanks for sharing the info on technique.  It's
given me some new lines to experiment in.  As Kyle pointed out, one can see
various forms within the image, kind of like a 3D Rorschach test. (A mysterious
hooded magician and circular face with a great big grin jumped out at me.) Nifty
stuff - I'm looking forward to more.

Best Regrads,
Mike C.

A picture very beautifull, but some dark... excellent technique, I like it.

Need too much render time?

Wow, this is very nice!
It seems like a glass coral structure.

Very nice ! Just for information : how long did it take to render this 
scene ?

Thanks for comments. :)

Rendertime was relatively low, just a bit more than 2 hours with Anti-Aliasing.
The limiting factor for the quality of the photons was only memory. It used 1.2
GB allready, so i couldn't increase their quality that much without filling
memory completely (2 GB).
