Inverting Things with SphericalA few uses of spherical. Those are not all, not any close to it even, but hopefully a good bunch of directions and ideas.
Part of "structured IFS" Series
Circle / Spherical
To make an inverse of a circle, you can use spherical as linked transform:
Circle_blur (left) and same with a post linked spherical (right)
Hypertile (left) and hypertile with a linked spherical (right).
When you need to create an inverse but don't want to interfer with the shape, you may use 2 chained sphericals. Their effect on the other transforms will cancel each other (one inverts the circle, and the next one inverts the inverse of the circle, bringing it back to the original shape).
Lets see another example, disc + julian (Apo-Tuto_Disc-Julian
Structured IFS tutorial collection well, as usual, i need your help with this bunch of tutorials.
What should i write about? Is there anything you wanna know? Please ask, i´ll write about it ^^
If you wrote / want to write cool tutorials about structured IFS, poke me, i´ll add it to the collection.I need feedback Is anything too crappily written? Is it messy / unclear? Do tell!

Common Render and Postprocessing MistakesA low quality render can ruin an otherwise great artwork.
For each, two images will be presented: the first one, a decent render, and the second, a messed up one. All examples were rendered in Chaotica, but the thoughts apply to all fractal software.

Fast Noisy Render
Basically, when the fractal is not rendered long enough. While in very few cases this may be used as artistic effect, usually it just gives the fractal an unfinished and unpolished look.
Here is a good and reasonably smooth render.
Now, the very same fractal: the only difference is the render time - way too short. See how terrible it looks compared to the previous one.
Blurrying the noisy image in Photoshop: the blur will smooth the grain out a bit (grain still visible though), but also kill all the tiny fractal details:
Hypertile BasicsFirst of all, special thanks to Zueuk who had the patience to explain me all the hypertile stuff
There is also an awesome hypertile tutorial that you should check out first: Hypertile Uncovered With 3D
To make a basic hypertile, you will need 2 transforms: Basic hypertile
hypertile2, rotated 180 degreesbubble (small amount, about 0.25 lets say) with pre_blur
The exact bubble size to fill a hypertile can be calculated exactly, or you can just change the amount of bubble until it fits.
The hypertile has two parameters, p and q. Basically, this means it takes p-gons, with q polygons meeting at each vertex (this does

Yeah, I'm not able to speak English, so please do not worry about late reply.
