Welcome back, Mike.

I hope you enjoy getting back into POV-Ray.    I'm familiar with some of your
past excellent renders.

These new ones you've posted are beautiful, both in composition and lighting.

Sergey (yesbird) is certainly going to enjoy those landscapes!

Bald,
again, you are reading my thoughts :) I wanted to reply to author, but 
was not able, as his email of incorrect format.

I am looking for the similar methods for generating forms like on 
attached image.

Thanks,
Yes, just getting back into POV. It's been a while...almost 30 years. uggg.
Glad to see there's a strong interest going on here. I'll post renderings as I
work through concepts. I'm currently coding some landscape/plant macros for
world building.

Sorry, just fixed the bad email link in this account. Below is my correct email.
mil### [at] gmailcom

I use macros to return point clouds of various shapes (spherical, cubic,
pyramidal, torus, etc.)  I position and scale groups of these point clouds to
create weird plants and forms. I convert all the 'grouped' points to one blob
using sphere size/scale and blob threshold to control the blobbing. I can post
my scene code.

Attached uses modified point cloud shapes to create the plants and land bridge
forms. I use a seed to randomize the points in the cloud macro.

Hi, Mike !

Glad to meet you. I am very new to POV and now working on two projects:
one is Matlab toolbox for POV rendering: 
https://www.mathworks.com/matlabcentral/fileexchange/123520-pov-lab-matlab-interface-to-pov-ray

and another is a set of futuristic landscapes, inspired by works of 
Roger Dean (https://www.rogerdean.com/).

I am only starting selection of methods and techniques and see that your 
forms are very close to what I would like to include in my scenes.

The only serious difference is a shading, I am prefer something more 
cartoon/poster like, but this is another story.

I am reading this tutorial now: https://povlab.online/isotutorial/, and 
suppose that in combination with your methods I will get what I expecting.

In general I understand your idea about combining point clouds into 
blobs, but I am not experienced yet working with this objects, so if you 
will share your code with me, it will be very helpful, and become a good 
starting point.

Thanks in advance,

Hi YB,
I put a small scene together with a few of the blob macros.  Attached is an
image using them to create a more cone-like shape. It's not tales from
topographic oceans but it's a start. :) I like the endless curve forms that can
be created. I clipped/intersected a few inside a sphere to get a smooth top cap.

What is the protocol for posting code. Can I dump it to a message window or is
there a place on the forum to post .pov files?
Thanks.

Hi YB,
I posted the scene file for that image. Sorry, there's tons of #declared stuff
that's not used in the scene. It needs to be stripped down. Let me know if you
have any questions.

The usual places - text files for ASCII scene file, binaries for zips and such.
 Short scenes or code snippets inline with the message.

Chris was very accomodating, and changed the forum structure so that we could
now attach anything in any of the groups, so there's no longer a need to post a
render in binary images, the corresponding scene over in text scene files,
etc....
