Ultra Fractal 6 is a great way to create your own fractal art. Today, fractals are much more than the Mandelbrot sets that you may have seen before. With Ultra Fractal, you can choose from thousands of fractal types and coloring algorithms, zoom in as far as you want, use gradients to add color, and apply multiple layers to combine different. Ultra Fractal 6 is designed to run on any computer with Windows 10, 8, 7, Vista or XP, but it works best with Windows 10. The new High DPI support requires Windows 10 or Windows 8.1. Ultra Fractal will run on any CPU that works with Windows, but Intel Core i7 or i5 processors are recommended for best performance. Ultra Fractal Key. Ultra Fractal A program that allows you to create images of fractal sets, as well as perform their animation. The process of building images is determined by a set of algorithms describing the types of rendered fractals, methods of their coloring and transformations applied to them.
Instructor: Kerry MitchellLesson 6: Publishing Your Formulas
When you’ve worked hard on a formula and gotten it just the way you want it, it’s natural to want to share it, so that others can share in the joy of your creation and so that you can give back to the community. The Ultra Fractal Formula Database is the perfect vehicle for this.
Have a Plan!
Ultra Fractal 6 Key
In MY opinion, only quality formulas should be submitted to the database. Also in MY opinion, the first step on the way to creating a quality formula is to have a plan. Creating a formula is creating a software product, and every good software project has a plan behind it. As you may be sensing, it’s very easy to write a formula with a lot of bells, knobs, and whistles. While these formulas can be fun to play with, they also tend to be very difficult for users to understand without an overarching idea. Debugging (finding any problems in a program) a formula is much, much harder if you’re not sure what the program is supposed to do. Also, if you have a plan for the formula, that will help you to explain it, which will give users a reason to use your formula instead of the thousands of others.
The plan doesn’t need to be fully fleshed out before you begin writing, but you should have some idea of what you want to accomplish when you begin. When I wrote the Rational Newton Mandelbrot formula (in lkm3.ufm), I started out wanting to write a formula that combined the traditional Mandelbrot features and the Newton’s Method features. As I got into the formula, it became apparent that I needed various parameters. Then, enumerated choices came to mind. Then, I figured out that I could combine embossing effects into the same formula, rather that writing two formulas. Etc., etc., etc. At each step, I had a plan for that step (e.g., what kind of variable, would it be an internal variable or a user-specified parameter, what type, how is it initialized, etc.), and those smaller plans fed into the larger plan.
Have a plan. Take notes, if you need to. Revise, rethink, and rewrite your formula--just have a plan.
Default Parameters
When you load a formula, all of the parameters have default values. For example, the default Bailout value for the Mandelbrot formula in standard.ufm is 4. When you write a formula and define parameters, you need to set the default values. That’s good, in that you have control how the formula operates when loaded, but that also makes you think about how the formula will operate when it is loaded. Don’t just set everything to 0, nor make up random values. Come up with an image that your formula can generate using the default coloring formulas and set the parameters accordingly. For example, the default Bailout value in the Mandelbrot formula could have been to 0, but that would prevent any of the set from showing. If the user didn’t know about the Mandelbrot set, then she would not know the set the Bailout to at least 4 to see the entire set. Or, the Starting point could have been set to 1/0, but that would give a warped version of the set. If there’s a regular or standard shape that your formula gives, you might want to set the default parameter values to generate that shape.
Backwards Compatibility
If you’re revising a formula that has already been submitted to the database (remember to only modify your own formulas unless you have explicit permission from the original author), then remember that many users may have already created images with the older version of your formula. Therefore, any changes you make to your formula must not break backwards compatibility—the new formula must recreate old images exactly as the original version did. You can break compatibility in many ways:
Ultra Fractal 65
- changing the formula logic
- adding new modes and incorrectly updating the enumerated parameters
- changing parameter types or limits
- removing or renaming parameters
- incorporating features of a newer version of Ultra Fractal that aren’t supported by older versions
If it turns out that you can’t implement the new features with breaking compatibility, submit your formula with a new name. Once you publish a formula to the database, you are undertaking an obligation to leave it out there for public access indefinitely. That is why it is so important to test your formulas before releasing them. In that way, you can avoid having to update your formula immediately after it was released, potentially breaking many parameter sets that were created with the earlier version.
Testing, Testing, Testing
Another aspect of a quality formula is that it has been extensively tested. In the software engineering community, three levels of testing are commonly identified: alpha, beta, and gamma.
- Alpha testing is the most basic level that every program undergoes. This is what the author performs during the early part of the program development. For our purposes, alpha testing is when you finish a version of your formula, use it to create an image, find out that it doesn’t work or doesn’t work the way you want it to, and rewrite it.
- Beta testing is generally done with a small group of trusted users. Typically, the users have some knowledge of the project or of the system and the program is almost complete functionally and largely complete cosmetically. With us, it means finding a trusted small group of experienced users (as opposed to a group of small, experienced users) that are willing to try your formula. Your formula should be in pretty good shape, with all the logic and parameters in place. You can use feedback from the beta testers to write comments and documentation for the formula (more on that later).
- Gamma testing is generally reserved for larger programs. End users who might not know anything about the program or the platform are exposed to it to see what their reactions are. For us, this is not practical, as almost all problems are found in alpha or beta testing, and it’s not a good idea to turn newbies loose with new formulas in an uncontrolled environment.
Ultra Fractal 6 Review
Alpha testing is required, as you can’t get a formula to work without it. When you test your formula, try to think like a new user and distance yourself from what you know your precious creation should do. Try various combinations of parameter choices and see if you can break it. Remember, most people who use your formula won’t know you or what you had in mind, so make it as easy to use as possible.Ultra Fractal 60
To help with your testing, you can use UF’s print() function. Once you enable it, you can use it to print values of variables or text messages to the Compiler Messages window. Use this to help find out how code is actually working, as opposed to how you want it to work. For example, to print the value of z, turn on printing by placing this line in the beginning of your program:

Then, place the print command wherever you need to print something:
