I’m finding that Mandelbulber is really addictive. First off, two Mandelbulb explorations:
I wised up and started doing a 1px field blur in Photoshop on the rendered images, which helps a lot in getting rid of sharp artifacts. On the first image I also painted in some dots and ran lens blur.
Next, a Mandelbox (Tglad’s variant):
I cheated a bit and used the liquify and oil paint filters in Photoshop to get a more surreal, painted look (hopefully giving it a little more humanity, making it less sterile).
Finally, a Menger sponge:
Going for a folk art look here. I will try very hard not to overuse the oil paint filter. I really will. I promise.
Some more Mandelbulbery, this time exploring the Mandelbox fractal instead of the Mandelbulb:
My process for these is to choose a fractal type in Mandelbulber, play around with the fractal parameters till I find an interesting shape, move the camera around until I get a good view, and render it. I then tweak the shader values (colors, specular, ambient occlusion, etc.) and the lights (position, color, etc.) and re-render till I get what I like. Finally I turn on depth of field and add a little fog.
Once I’m happy with the image in Mandelbulber, I export to PNG and open it in Photoshop to add some texturing. I also scale the image down a bit to get rid of some of the rendering artifacts. (It’s not wholly successful, but it does make a big difference.)
And here we are going for an underwater type of atmosphere (via aqua-colored fog and some vignetting in Photoshop):
I’ve been playing around some more with the L-system code and modified it to animate the angle property and output each frame to a file. I also added some color and started using blending modes for the brushes. Once I clean up the code, I’ll post it to GitHub.
Anyway, here are some of the animation tests (I used Blender to put the frames together into an animation):
And the first one I did, which is a little too long and a little too fast:
The algorithm isn’t entirely accurate — at least based off of the axioms and rulesets I plugged in from the Algorithmic Beauty of Plants book — but I like what I’m getting. I’ll do a second app sometime later with the correct algorithm.
Anyway, the code (which is kind of messy at the moment) is on GitHub. Sometime later I plan to add color selectors and more brushes. You can see the rest of these images in my sketches set on Flickr.
