So that's why I'm wondering why fractal related service like FractalForums almost doesn't give me any feedback (the same was for MB3D). It's difficult to develop the software, especially cross-platform, when you event don't know if it works properly on different systems.
Sorry to hear that. At the moment my time for experimenting is pretty limited. It would take months to convert my workflow to a new paradigm, especially in animation. Time I currently do not have. I am pretty familiar with the old GUI and mostly happy with the features, so it is hard for me to find a convincing reason for the change. I hope I can spare some time in near future, but I can't promise...

Thanks guys for feedback, (albeit you three are not  feedbacking newbies, having already helped us a lot in the past), and I fully understand the time constraints.

pause,....  then I ramble on .....

The latest version has only been released a few days, so in some ways it is a bit early for much feedback, other than "Material Manager looks great".  I still need to test this feature out more myself, BUT, I do know that it is a powerful enhancement for Mandelbulber, and means to me that Mandelbulber is now finally functionally completesmiley smiley smiley

@Buddhi, feedback from V2.07 .... I have only recently tried the Fresnel's equations for reflectance, and liked what I found. A Beer Cup A Beer Cup A Beer Cup

This is an example of MandelboxMenger hybrid,  with some basics for newbies to the program.

1) In the example the MengerSponge part is run only on iteration 4. A single iteration of another fractal to make a hybrid is often the best practice.

2)  In the Statistics (enable in View menu) you can see Percentage of Wrong Distance Estimations ("Bad DE") is 0, which is good!!. As a general rule less than 0.01 is good,  but it is case specific and 3.0 sometimes is OK and .0001 sometimes is not.

The Raymarching step multiplier or "fudge factor" (Rendering Engine tab) is set at 0.6, which is good for a hybrid. If I change it to 0.7 the Percentage of Bad DE leaps up to 0.25 and you can see the areas of quality loss on your image.

Now if we disable the addCpixel Axis swap Constant Multiplier, we find we can now increase the Raymarching Step Multiplier to 0.9, and get a faster render and visually the same quality.  So monitoring Percentage of Wrong Distance Estimations  is a guide to managing quality. ( Note when doing animations you may want to drop the Raymarching step down a bit to allow for what might happen between keyframes.)

3) MandelboxMenger Hybrids can behave a bit differently to a lot of hybrids, in the fact that the  Percentage Bad DE often improves when you zoom in.

This example is using Msltoe's toroidal formula at the beginning of the loop with Benesi  T1 PT as the main frcatal formula.

Here the Percentage Bad DE is 0.28, which normally is real bad, but here just a bit bad, I try and hide it with fog. It looks OK-ish but if I zoomed in it would look worse.
 
Another issue is that the Percentage Bad DE  is possibly more like 0.8 because only two thirds of the image is fractal. The other third distorts the percentage by being being recorded as good DE. (if i have this right?!)

I think that probably the best use of Toroidal, is  to hybrid with other mandelbulbs or julia bulbs.   Often Force Delta DE is required (render engine tab)

I received a warning from SourgeForge that a new version was available of Mandelbulber v2 - 2.08,
http://www.graphic-unlimited.com/photos/1467809524_808898130.jpg

Maybe it would be an idea to do the same here.  That whenever there is an update or a new program all members that are interested receive an email with this news.  And it would be nice when a thread about updates or new programs are discussed in a way that it stays in the spotlight so to speak.  Perhaps a special section that is an eye catcher on the side to draw attention.  

It also would be nice (if possible) that members for example like me that don't understand all the ins and outs of a program could be more interested for these programs.  It can be quite intimidating for members/newbies to listen ( roll eyes to the flood of technical details.  I understand that you can't make a version for 'fractal dummies'  wink  but maybe there is still a way to make it more attractive.  It would be good for more attention and stimulate people to dare to use a program they don't understand or just for a bit.

Whatever, I'm glad you fractal-wizards take the time and the effort to make these great programs for us to use.    A Beer Cup A Beer Cup

It's good idea about mailing list. I have to find some solution how it could be managed, because actually I don't have any list of users. Maybe cKleinhuis can help us in this matter. I have also to think if I can implement this directly in the software to inform users if new version is released. The program could check if newer version is already on the SourceForge server.

theoretically it would be possible through some kind of webhook that is triggered through a master github branch release or something, BUT it would be some handwork needed, we do not really have a close connection to development servers, and i am not aware of a board plugin that could do such, informing users wont happen throughout the forums because sending of emails is always a pain, a notification system on a per user base is not known to me at the moment as well

we could implement some auto webhook callback that someone could connect tio github, but i am not aware of what others things might come out of it, creating a thread for a new official release is the only thing we can offer, and it is not too different from current method sad

What about a classical mailing list at gnu:
https://lists.gnu.org/mailman/listinfo

You can Register/unregister in the webpage of GNU (really easy and intuitive) then you can send a mail to mandelbulber@gnu.org and all subscribers will geht the message delivered. I am in a couple of mailing list and this system works Quite well.

Example of using Transform_Menger Fold

On this transform UI,  the standard menger sponge formula is split into a start and end function. The simplest way to use this transform is in Hybrid Mode, having the menger fold transform in slots 1 & 3. In slot 2 place any linear type formula or transform. (ie more mengers, kifs, mboxes, amazing surf, folds, rotation , Benesi T1 etc).

In slot 1 disable the stop function  and  in slot 3 disable the start function, resulting in a standard menger sponge with something in the middle.

BTW in fact you can mix around with the start and stop functions have all enabled if you wish. Generally linear functions all work well together in making hybrids.

In Statistics, maximum is 79 iterations. Generally hybrids take longer to render than standard formulas.

As well as adjusting formula parameters, you can use the iteration controls to tweak hybrids. In this example the first slot is set to repeat for 5 iterations before moving to slot 2. Slot 2 is set to stop at iteration 12, whereas slots 1 & 3 can continue to  default end iterations = 250 (but actually have met termination conditions (bailout) before iteration 79).

In the example above, slot2 of the hybrid sequenced ended at iteration 12. 12 was chosen because how it fitted into the iteration sequence, as follows:

Slot1 x 5
0,1,2,3,4  iteration numbers (note first iteration is iteration number 0.)

slot2
5

slot3 
6

slot1 x 5
7,8,9,10.11

slot2
12  // last use of slot2

 sequence continues slot1 x 5, slot3, .....to bailout.

So slot2 is used only twice in the iteration process. If I had entered 11 instead of 12 for slot2's stop_iterations, then the slot would have been used only once, if I entered 19 then it would run three times.

Buddhi,

I've very much enjoyed Mandelbulber and I've been using it daily for over a year now, through several different versions. I've been struggling to figure out the OpenCL version, and I think I've got most of it figured out. I wish I could do more OpenCL fractals than just the Mandelboxes, Bulbs, and a couple of other minor algorithms. I set up a render farm with a couple of hundred cores and I've been producing about 1 CPU video and 3-4 GPU videos a month. I'm a multi-instrumentalist composer, writer, and producer and musician, and I wanted to make cool videos to go along with cool "soundtrack" music. I've put the two together and have done a bunch of "3d Fractal Animation and Music Videos" and post them on Youtube and better quality Vimeo at my channel called "Fractals."

https://vimeo.com/channels/fractals

CPU render farm: 215 cores
GPU: 2 sets of GeForce 980s overclocked.

I've never posted here to the forum because I didn't want to get in the way of the pros. But reading about how you didn't get much feedback, I can certainly do something about that! I've had a whole host of issues that I've resisted asking questions about and just tried to figure things out for myself. I'd love to give you more feedback. But just wanted to say Hi and thanks for this wonderful program. I've done almost 50 different 30 FPS videos averaging around 7000 frames per video or so. My early vids are primitive compared to finally learning how to use the focus effects, and textures. I can't wait to dig into more textures here in the new version. Thanks again for the awesome Mandelbulber software, both the CPU and GPU versions. And please I'd love it of the GPU version could do more fractals than just Mandelboxes and bulbs. It's just SOOOO much faster than brute force CPUs.

Thanks again! Cheers!

So, finally I had a little bit of testing. Here some observations:

positive I see the translation. The native german version is very convincingly translated. Maybe some things - ambient occlusion, just to give an example - should stay english, as they are more common as the translation.

A serious issue, I had in the material editor.
Placing the texture center is hard, if not next to impossible.
  • the numbers are limited to 5 decimal digits. It says relative to object, but in a moderate magnification I had to fiddle around in the third digit, so I assume some sort of absolute placement
  • there is no way (I didn't see one) to grab a point from image
  • even in combination with the measurement tool, it is not operational, as the texture center did not accept copy/paste values (the texture scale does, which is useless)
I managed to place a texture pecicely, but only with a lot of manual adjustment. (I attached one  wink)

Annother issue I had with the slider for transparency of volume. it starts to jump around between two visible scales, when leaving 1 (the slider's length on screen jumps between two states). I attached a screenshot, to show what I mean.
At this point I think it's time for a general note about the slider concept. For me, many of them (or should I say most) are useless, as they are not fine enough, have an unappropriate scale or simply do not act as expected. If this is an attempt, to create a m3d-like GUI, it is more than half-cooked. M3d users (and I am one) won't feel familiar with it - sorry to say that.

All in all, the new material manager is a pretty good start. It acts like I am used to from professional 3d bundles like c4d or blender. Further features could be image maps for transparency or an alpha channel to stack more than one material. Besides that you're on the right way, I think.

Thank you @taurus. You gave me a lot of useful information. It's my first attempt to implement texture mapping, so it needs many improvements.
About positioning of textures, what you think about following solution:
- Indicate point where top left corner should be placed
- Then indicate top right corner to set horizontal scaling
- Finally indicate bottom left corner to set vertical scaling

Sounds great, if you leave the manual adjustment untouched. They are maybe useful for fine tuning.
