Hello fractal friends,
I hope you all enjoyed the June HalleyNova challenge! This month your task is to explore a formula called 3 Functions Mk II
which you will find in jam3.ufm.
This formula by
looks very interesting because of the number and type of parameters it has.
Text within the formula describes it as:
"2 or 3 different Mandelbrot/Julia style formula are executed and combined in a user-specific manner, either each iteration or every N iterations".
You will see that up to three formulas can be used together. You don't have to use them all, changing two of them provides plenty of fun! I would seriously encourage all of you to have a really good play with these parameters before settling on anything, though - the possibilities are immense. You should really set aside a little time to get to know this formula and the sort of things it can do because it might be one you can use over and over in future. I'm confident you will enjoy this one, it looks fun!
If you can share your params or perhaps a base layer for your image that would be terrific. Please consider doing this so new users (and perhaps others too!) can benefit from what you have discovered. Thanks. Tips for use:
I have no experience of this formula myself until now but having messed around with it for a short while I have a couple of tips for you:
- If, on changing the params for one of the three formulas you end up with a stubborn blob of solid colour in the middle (looks a bit like an Inside colour but isn't) you can remove it by setting the last Postmultiplier (Re/Im): to 0/0 for that formula.
So if you change the function of Formula F, for example, you would look at the last Postmultiplier below that formula section: Postmultiplier F (Re/Im). You will see the default is set at 1/0 so just change it to 0/0.
If you use a second (or third) formula you may need to look at their final Postmultipliers too.
This only applies to some some compositions, not all. It may not even be a good thing to do, it's just something I found worked for me.
- Try using "biomorph" colouring in jam2.ucl with this formula. At the bottom of the 3 Functions formula is a parameter you can enable called "Biomorph Bailout" which gives some nice results. You will see a note on Biomorph.ucl about using that option:
"'Biomorph' is designed to be used with a fractal formula that supports Pickover's biomorph bailout conditions, such as '3 Functions Mk II' in the public folder 'jam3.ufm'. If using that formula, enable the final parameter, 'Biomorph Bailout'."
As I can find no examples of this formula in use in DA's galleries to show you we will just have to explore this one together!
Here are the full challenge rules. Please read through them before submitting to ensure your work follows the rules. I need to be fair to everyone participating and do so hate having to decline images so please check you've followed the published rules. Thank you and I hope you enjoy the challenge - I'm excited to see what you all come up with!
Rules for this month's challenge
Images must be made with Ultra Fractal software.
Images must be made with one or more layers of 3 Funtions Mk II
formula in jam3.ufm.
Images must be new and uploaded to DA on or after: 1st July 2019. The challenge ends on 31st July 2019.
You may enter up to FOUR images to this challenge. If you have any problems please note the group, not the admins.
You MUST mention this challenge and add a link to this journal -OR- our group icon in your comments.
Submit your entry to the Challenge Folder: July 2019 Challenge: 3 Functions Mk II
After the challenge closes we will ask the group members to vote on their favourite three entries. A selection of winners will be featured in the group journal shortly after the voting period ends.General rules
You may use mappings, masks and texturing created by UF.
Watermarks and signatures must be small and subtle
Minimal post-work only allowed e.g. enhancing colours, sharpening and adding a signature or simple border.Sharing parameters
Please share your parameters wherever possible!
You may paste your params in your artist comments, as a comment to your image or in your Sta.sh with a link. A tutorial on how to store your parameters in your DA Sta.sh area can be found here: LINKQuestions or don't understand something?
Please ask first as we do not wish to offend or upset anyone (and ourselves) by refusing an entry.
Add your questions in the comments below, for the benefit of all.Remember:
No question is too silly or too basic and you're not being useless because you don't "get" something! I really do forget to mention stuff, get things wrong or can overlook the fact that some things can be baffling to new users or new members, so if you're not sure about something please do not be shy to ask!
Others may be wondering the same thing too!
Thanks and please have fun and enjoy this formula challenge!
