 Whenever I try to work with it , well it's sooo very slow I almost always give up.  Is this common & does anyone know why?    huh? Thanks in advance for any insights! kiss

Hi,

Whenever I try to work with it , well it's sooo very slow I almost always give up.  Is this common & does anyone know why?    huh? Thanks in advance for any insights! kiss

could you please post the parameter set which is so slow? I guess some parameters are set wrongly...
Just press Ctrl+C in the window where the fractal is generated and paste the contents of the clipboard into a thread here...

Kind regards,
Martin

Putting contents mot gonna work for me!  (have no clue)  But it is when I choose as a default time. Formula is "hybrid in ChaosProcfm."  BTW these are "preset parameters" (not mine)

Hi,

A "standard" Mandelbulb starting point (available as a preset in ChaosPro) is the following: Just Copy&Paste into ChaosPro.

Well, as the formula used to create that fractal contains an error, ChaosPro cannot render that fractal.
ChaosPro cannot correctly import that formula as it has been written for UltraFractal and not all features from UltraFractal are available in ChaosPro.

When you wrote that ChaosPro needs ages to render a fractal, did you actually mean this effect here? Did you just wait for the black window to disappear? Well, it won't...would be better to display a big "ERROR" inside the window, I guess...

Kind regards,
Martin

I think that would mean when they say "report bugs"  When I changed parameters it did improve...  Thanks for all your help!  embarrass

Actually, whenever ChaosPro did happen upon any detectable error using a formula, parameter, file, etc., then it would be nice to get such a message under those circumstances.

Ok, I don't remember why I did not implement that from the beginning: Instead I let it calculate a complete black fractal without any loop, although ChaosPro exactly knows what went wrong.

From all the times I have used ChaosPro, I never noticed this "black screen" before. 
I guess I never used anything that would have caused this to happen.  I was usually too busy creating images with valid formulas and parameters.   wink

Should have seen THAT coming! grin If I changed now it would be even more confusing.  Not sure how some got to the "black screen" idea.  It does open up..just really slowly.

Quaternions are slower than Escapetime fractals in Chaos Pro.

I usually just reduce the image size to the smallest (320 x 240?) for playing, and increase it when I find something interesting I want to render  educated

That speeds things up a lot when seeking interesting forms to render out at larger sizes.

I can do that!  Makes sense to see if I really want to persue.

Well, if you had a black screen appear slowly, then there was another problem...

Anyway, you now know how to paste a parameter set in here, and if you still encounter that problem, just post it here so we can give advice.

One of the main drawbacks of Quaternions in ChaosPro is that there are totally confusing parameters which need to be adjusted continuously (i.e. when zooming in/out, changing other parameters...).

Martin I just wanted to thank you for creating CHAOS!  Also for taking the time to take the time to help us "lesser beings"   You are very gracious for giving such ibdividual attention .  cheesy cheesy cheesy
