A few weeks ago I was using AI to generate some Blender bpy code. It was a mixed bag, some success and some fail. I got something working.
It occurred to me to ask for code to show a chaotic function, but which one? The Lorenz Attractor turned out to be a good fit. With a bit more work, I managed to generate a fun video showing what it would look like to ride it!
Here is a render of what it would look like to ride the Lorenz Attractor.
My second experiment with a scripted generator. At this point, I was looking for some basics. I got a lot of help from Gemini, but ChatGPT got it over the line in the end.
This is another revisit of the Lineseed idea (starting in 2022 and earlier). Lineseed features bold black lines over a white background. The eight images here are keyframes from a short video loop of a flight through the generator object.
This Lineseed revisit is probably my most efficient generator idea of this sort. Each line source is a mostly round icosphere with 42 corners, and a line particle emitted from each corner. Those icospheres are in turn emitted by a larger icosphere. The result is a lot of black lines that emerge into a symmetrical pattern. Both, the small and the big icospheres operate with parameters, so everything in the scene can be experimented on by changing numerical values. The generated outcome is limited by available time and compute power. The only manual design in this scene is the camera placement, but even that was limited to a simple movement along a single axis.
This is the IGSIFY 2025 reboot!
IGSIFY images are mostly abstract and vague. They can be transformed without compromising their essence. It may not matter how you stretch, flip, layer, or remix them. For these reasons they make ideal backgrounds for promotional collateral or decorating.
Here are a few more renders of glass. The glass material shows a colour spectrum attempting to mimic a prism. Unfortunately there is a quirk.
For each of the rainbow colours that we normally associate with a prism colour dispersion (red, orange, yellow, green, cyane, blue, and violet), I had to use a separate IOR (Index of Refraction). The problem is that a natural colour spectrum is continuous, rather than made of a set of seven colours, so it looks a bit different to what would normally be expected. The resulting effect is a bit hyperreal, but still fun.
Over the New Year break, I experimented with geometry node spirals and sound design.
The video loop was rendered in Blender EEVEE. The sound track was designed in Ardour, and probably a spagetti of connections with ZynAddSubFX via Patchance which does not save well in its entirety so I’m not that sure since the time when I worked on it.
I found this cityscape that I designed earlier in 2023. It just needed a bit of work to set the mood and be able to get some decent images rendered.
Blender geometry nodes make generating arrays of objects relatively quick. Compositing nodes add that extra wow to the whole scene. Applying both make generating colourful video clips a breeze.
This was an experiment in generating a simplified scape from cubes. As the project developed it ended up looking like a street scape.
The aha moment was adding a variation to the monotony, by way of a rainbow mimicking central intersection. Incidentally, I would have borrowed the idea from something I had seen.
