Think of tags as like a book index where you find words and which pages they are on, the same principle applies here. Although it's taken a stage further so it might not be the word, but the subject, so for example if you're looking for things to do with fractal gradients for example. A tag may bring back posts with gradient files, as well as posts that discuss gradients, or tutorials about them.

Elliptic

The most commonly used coordinate systems are rectangular coordinates and polar coordinate. But these aren’t the only possibilities. One of the less common coordinate systems is elliptic coordinates. Although their mathematical application is specialized, they can be used in variations to make interesting flames.

bipolar

The most commonly used coordinate systems are rectangular coordinates and polar coordinates (see polar). But these aren’t the only possibilities. One of the less common coordinate systems is bipolar coordinates. Although their mathematical application is specialized, they can be used in variations to make interesting flames. Rectangular coordinates are based on two families of parallel lines (horizontal and vertical) where each line in the first family intersects each line in the other at a right angle.

text6

text_wf

The text_wf variation incorporates a line of text into a flame. It is a blur variation like circleblur and starblur, meaning it ignores the input and just generates a shape; but instead of the shape being a circle or star, it is a line of text. The brain processes words differently from images, so this can add a new level of depth to fractal flames. Or the text can be a single symbol (not necessarily a letter), using text_wf as a blur with a specialized shape. Text_wf can be quite versatile.

glynnSim9

glynnSim

The glynnSim variations are a cross between linear and spherical. Using the unit circle as a dividing line, their output has three parts:

Outside the unit circle is whatever was there before (like linear),
Inside the unit circle is a reflection across the unit circle of what was outside the unit circle (like spherical), and
The points that were inside the unit circle are replaced with a blur:

linear16

linear

Although “linear” seems a strange name for a non-linear variation, it’s a really important one. The name makes sense in the context that it means not to use a non-linear variation, just the affine mappings that are part of every transform. When a new transform is created, it is assigned a variation of linear3D with an amount of 1, which just maps the input to the output without any change.
