I wish I had the originality, creativity and vision to be able to make the patterns that you post.
The tools have gotten so good its getting easier and easier to start learning 3d modeling. I won't say its easy but its no longer the unreachable goal anymore. Home computers are so powerful now you can make full length animated movies on them. There is free software to start learning.
If you stick only to the 3d modeling section, Blender3d is very approachable. There are a ton of free learning tutorials online and they are very, very good.
If you outgrow Blender then Zbrush is the industry standard for artistic 3d modeling, but it just got sold off and the first thing the new company did was make it subscription. I will be sticking with the last 2021 version that was not subscription and since I only use about 5% of it now I will not outgrow it for a long time, if ever.
