I've got a major issue with this coloring algorithm which won't render to disk. Unfortunately it's crucial to a design and I've drawn 10 layers apart, rendering them separately to disk until I discovered the culprit. My guess is that it leads to some sort of infinite loop in the rendering process which prevents UF from completing the task. I've also updated all files of the public formulas. If an
This is the last part to the tutorial. All of the example uprs use plug-ins for the Colors slot. Two of them are slow in rendering as they use an emboss convolution filter (3 min 31 sec for EtchedMetal and 16 min 22 sec for EmbossedGnarly on my computer - Intel quadcore 3240 3.4 GHz). Be sure you have Ultrafractal set so that the minimum number of threa
In writing this tutorial some bugs were found in some of the plug-ins. Please download a new copy of reb.ulb before continuing.
Continuing with a survey of the main plug-in slots the next section is Images and Coloring. The primary slot is Colors with a default plug-in of No Color. The base class is ColorTrap, which is in common.ulb. The following plug-ins will plug into the Colors slot, but
This formula is derived from the Ducks formula in sam.ufm with multiple modifications. Bailout is determined by the number of iterations rather than a convergence or divergence criteria, so an iterations parameter which is independent of the value on the Maximum Iterations value on the Formula Tab has been included. The value for 'Iterations for Bailout' must always be less than the Maximum Itera
Ottomagus suggested some additional functions to add to my extended function set that is used by Smooth Alterations, Ducks Switch and Lucy Goosey Switch. The coloring formula Smooth Alterations is the simplest test bed so I started there. After testing and debugging I have uploaded the latest version of Smooth Alterations to the database. Lucy Goosey will be next. Here is a quick example with th
It's not a bug but 2 years ago I made a fractal with Itelinsky in eew.ufm (this formula was added jul 31, 2014, reported in the list of modifications). Can anybody tell me where I can find it? I don't remember if my fractal was interesting but I want to know if it is! With many thanks
This is a follow up to a previous question on using external imagery. I'm doing a series of color cycling animations primarily but not exclusively using fractals for the hypnotic effect to create quick meditation trance states. I've been able to get external imagery & correct the gradients to the actual picture but when I try to cycle the gradient it remaps each time to the original image col
Hi. is it possible to provide the option of alternative bailouts in the same formula?
More specifically, I wanted to include convergent and divergent bailouts: |z|<@bailout (default 4.0) |z|>@bailout (default 0.001) It seems only one expression is allowed in the bailout section. Is there a way to do this? Any help would be appreciated.
'Widgeon' is based on the same principle as 'Ducky Plus': change of the kind of operation during the iteration process. In 'Ducky Plus' there are 3 steps, each with a number of iterations, here in 'Widgeon', the second step consists of only one iteration. So for each treated pixel the iteration series starts with a certain formula, determined by the pa
I have started the plug-in tutorial for Image Traps. I have not done a complete inventory, but I believe Image Traps has more plug-in options than any other Ultrafractal software formula. Consequently there will be several upr examples, I am not sure of how many yet. Because of its image import capabilities I will also be including a link to a zip file on my website that has a number of images th
Hi Frederik, any progress on UF 6 ? And features such as array parameters or colour palette parameters ? Or how about a general data load/save were the data form (to a general memory buffer) is purely defined by the formula author - enabling direct input/output of 2D or 3D data for use in other software (or even allowing UF to be used to process other data forms such as sound data). Just wonde
I recently installed UF5.04 on a new Laptop with Windows 10 pro and a 4k screen. The fonts are impossible to read. I had this on an old laptop running Windows 7 pro and a much lower resolution screen and it was fine. HELP! Is there a current fix? If not now, when? Thanks.
For the Embossed Traps tutorial open Object Formula Switch Lite and load the the Switch Trap Embossed plug-in. In the Trap Parameters section note the Fractal formula plug-in, which is actually a specially designed Trap Shape that only works with Switch Trap Embossed. There are 104 to choose from. The default is Rose Range Lite and is closely modelled after a formula of Kerry Mitchell's. The Tra
For the Slope Lighting tutorial open Object Formula Switch Lite and load the the Slope Switch plug-in. Virtually any Switch formula can be used to apply the slope plug-in, but for this tutorial we will stay with Mandelbrot Julia Switch. The slope formula requires a specific coloring formula, called Lighting. There are several of them available in the Ultrafractal database. We will use Lighting wi
