Hi All,

There was one fractal last month.

A favorite coloring of mine in XaoS Fractal Zoomer is one called Biomorph. It changes shape depending on the bailout used. A low bailout such as 8 gives a stubby wider shape and a high bailout results in a more pointed, spike shape. See the pics here. Is there anything similar to this in Ultra Fractal? Jam2.ucl has biomorph and Outside Options under Fractint (Compatibility folder) also has bi

I've wanted to be able to add a vignette (a darkening of the corners and edges) to a fractal as is common in photo editing software, so finally I wrote one. It's Vignette in jlb.ucl.

It's a direct coloring, producing a layer with white at the center and grays to black at the edges. It is meant to be used as a top layer, with Multiply. Here are the parameters:

In the default section of a formula, I would like to be able to do the commented line below but the compiler does not allow it:

int param n1
min=1
endparam
int param n2
min=1
max=@n1 ; compiler says invalid setting

I've added a revised version of QuadMirror to jlb.ulb. QuadMirror2 is a transform that takes a rectangular block from a fractal layer and tiles the fractal evenly with the block, mirroring it both horizontally and vertically.

The user specifies the number of blocks in each direction, the center of the original block, and where the original block goes (unmirrored). Because of the mirroring, t

Rendering animations to png image sequence usually has several unfinished images. This also happens often when just editing a fractal. Refreshing zoom then gets rid of it.
Typical example included.

I've been having problems with what I believe are artifacts. They seem to have some connection with function settings, particularly exp, and cotan, cotanh, tan, tanh, cos, cosh, sin, sinh.

Here's an example from om.ulb, featuring a transform which maps according to various combinations of functions:

I am currently on working on creating some fractals and animating them.

I had a question... I tried doing a fractal animation and it takes about 3-4 days to render and then at the end the log says "Error Saving image (error)

Is there another log where I can figure out what the exact error was?

According to the log it took close to 60 hours to finish so I do not want to go through it

Does Ultra Fractal offer any of the lambda fractal planes, as described in this link? I am aware of the inverse fractal mapping but was wondering if any of these others are possible as well?

I stumbled upon an amazing combination of variables: the standard Pixel formula with Gradient for family Outside coloring (sam.ucl) and the Inverse fractal plane mapping. How does such a transformation take place from a bunch of squares formed by the gradient to a beautiful rounded geometric pattern? I am baffled and pleasantly surprised!

Any idea what's causing the black to appear over the fractal image? I suppose one of the variables is out of range but I happen to like the design I'm seeing on screen and don't wish to vary it too much. Thanks!

I usually render to disk with a resolution far higher than that of the fractal window. Sometimes, this means that perturbation mode would probably be used for the rendering, but I have no way of setting the precision level because it's only shown when that mode is also used for the fractal window.

Hence, I'd either suggest such an option in the rendering dialog, or to make the perturbation pr
