After the original new 3D Strange Attractor formulas I found here I have been playing with alternate formulas and came up with these 5 new types.
Here are the formulas used and some sample images of each type. The a3da values are parameters between -1 and +1 that control the shapes.
All of the above formulas are now implemented in the latest version of Visions Of Chaos.
I have more ideas to expand new attractor formuals in future versions of Visions Of Chaos. Firstly is to get a decent formula compiler implented so the user can try formulas easily by typing in the 3 formulas for xnew, ynew and znew. Once that works the next obvious evolution is to get it to genetically evolve and mutate the formulas like I have done for Genetic Art in the past.
i shared this page from your blog in my fb without asking you. hope u dont mind. thanks for sharing your work and pictures from math formula are beautiful.
Not a problem.
Hello, great work. Is there a way to export these as an OBJ file or similar?
There is no OBJ export at the moment. These images are created by calculating a “point cloud” of millions of points and then rendering them.
Would an OBJ file containing millions of points be helpful to you?
Sure that might be cool. I was hoping to import them into something like Meshlab or Blender
OK, I added in OBJ export for the 3D Strange Attractors.
I did some tests importing the OBJ files (approx 3 million points) into both MeshLab and Blender and they worked fine. I don’t know how to create meshes or solid objects from the point clouds, so if you do get some nice results I would like to see them. I was able to use MeshLab to simplify the points, but any marching cube options I tried crashed Meshab.
Download the latest Visions Of Chaos here (or if you already have it installed, select the Help -> Check For Updates menu to get the latest version).
Follow these steps to get an OBJ file;
1. Start Visions Of Chaos
2. Select Mode->Attractors->3D Attractors
3. Find a sample you want to export (click Search a bunch of times or load a sample)
4. Check the OBJ checkbox and then click OK to start rendering
5. After a few million points have been calculcated (or however many you want) click Stop.
6. The OBJ file will be written to disk and when done you will get a message telling you the location.
Let me know if you have any problems with it.
