Some might know Structure Synth - a 3D L-system - most won’t - but hey.
Did some work for it about 4 years ago and forgot that this is actually still live on a free hosting web site.
I will try to port it over to github.
A three.js live browser version of Structure Synth
Click on the links and a web version of Structure Synth will open and run the script directly - sorry - no object export in this version but I will try to get some into the one I will put on github.
Click “Hide code” and then you can zoom/rotate/move
There are also some examples and you can just use the code editor to make changes which will be reflected in the L-system
The three lines get you to more examples and allows code download and sharing
Don’t use the email in the about - that is also 4 years old and doesn’t exist any more.
