So, poca2hontas asked me if I'd be interested in writing a journal for the group, and once I got over the initial shock of realising that there are people out there who think I actually know what I'm doing (ha, I fooled you all!), I thought it'd be good to explain the steps I take in tweaking a fractal. 

Let's start by finding a fractal you like. There are plenty out there with params included, and I actually have a folder in my faves just for fractal params. It'd be a good idea to build a little cache of your own. 

For this demo, I'll just use one I made earlier:

Tempered In The Heart Of A Star by Holmes-JA

Here's the parameters if you want to follow along (though I would encourage you to not do EXACTLY what I do, as tweaking is all about experimentation). [Params] Just copy that and paste it directly into Apophysis. 

Let's go ahead and look at what makes this thing tick. 

So, we open the editor window, and as we can see we have 3 transforms, plus a final transform. It's important to know what you're working with. 

2017-06-14 15 16 06-Editor by Holmes-JA

Now then, make sure the 'hide unused variations' box is ticked, and have a look at each transform. On fractals with many transforms, I find that it helps to label them all with the variations used, so I don't lose track. You may want to also look at the Xaos, but I try not to touch that in case I break something. 

As we can see, on transform 1 we have flatten and glynnsim2, on transform 2 we have flatten, gaussian blur and pre-blur, and on transform 3 we have ngon. Keep transform 3 in mind, as it's going to be very helpful in our tweak. 

Notice I didn't mention what the final transform is. Why? Because when I do a tweak, I always start by getting rid of the final transform, and in this case, it leaves me with this:

2017-06-14 15 22 19-Apophysis 7x Version 15C.9  -  by Holmes-JA

Oo-er. Let's head on over to the adjustment window and scale it right back to about 20. 

2017-06-14 15 23 50-Apophysis 7x Version 15C.9  -  by Holmes-JA

That's better, we can see what we're doing now. If we move it around a bit, look at what we find!

2017-06-14 15 25 47-Apophysis 7x Version 15C.9  -  by Holmes-JA

Now that's what I'm talking about. 

At last, we can start to have a bit of fun. I like to start by using the variations we already have, and, to use the technical term, poking them. 

I start with the numbers, just dragging them up and down until I find something interesting:

2017-06-14 15 29 58-Editor by Holmes-JA

I'm going to save this, as I might come back to it later. 

Now, I played with xform 2's numbers a bit, but nothing terribly interesting happens there, and it's just the colour fill, so for now I'm going to leave it be. 

Now, on to xform 3. I'm again going to drag the value of ngon up and down until I see something I like. 

2017-06-14 15 33 13-Editor by Holmes-JA

There's a nice spirally sort of shape emerging there, I like it. But we're not done here! No, there's even more numbers to play with in the variables tab.

2017-06-14 15 37 43-Editor by Holmes-JA

Which reminds me, I forgot to look at the variables tab for xform 1, so we'll go and do that right now. But first, save a new version!

2017-06-14 15 40 14-Editor by Holmes-JA

Only small changes here. Now then, time to mess about with the triangles.

As xform 1 is the foundation of the piece, I start here. Let's see what happens when we rotate it, shall we?

We can make the spiral shapes much tighter:

2017-06-14 15 42 36- by Holmes-JA

Or much looser:

2017-06-14 15 43 56- by Holmes-JA

But I preferred how they were in the first place, so I'll undo the changes. 

Now let's see what happens when we make the triangle smaller:

2017-06-14 15 53 49- by Holmes-JA

I like that, I'll save it. 

And when the triangle is made bigger:

2017-06-14 15 55 23- by Holmes-JA

I don't like that as much, so I'll go back to the smaller triangle version (this is what the saves are for!). 

We can fiddle with the size and play with the rotation some more if we want, now let's see what MOVING the triangle does. I must stress that at this point things can get screwed up so save, save, save.

A bit of movement and a wee bit more scaling and rotating, and here's where I'm at:

2017-06-14 15 59 57- by Holmes-JA

I really like this, so I'll give you three guesses as to what I'm going to do with it. 

Now, let's try this same process out on xform 3:

Scaling xform 3 has more or less the same effect as changing the value of ngon, so let's not bother. 

Hm. After a little bit of playing, I've found that I don't actually want to move any part of xform 3. It's important to remember that sometimes it's okay to leave things alone when tweaking. 

I'll revisit this xform in a little while, but for now, let's see what we can do with a final xform, shall we?

My methodology for choosing the variation for final xform is pretty simple. I just try ALL OF THEM. I just cycle through with the scroll wheel, setting them on and then off again. 

However, I do make a certain beeline for variations such as spherical, bipolar, julian, and polar, as they tend to work very well as a final xform. Sky's the limit here, just go nuts, and SAVE all the ones you like.

So, here's what I ended up with:

2017-06-14 16 13 31-Apophysis 7x Version 15C.9  -  by Holmes-JA

Now, I like the pattern, but I'm not liking the blur fill, so I'm going to mess about with that for a bit, and do a bit of final tweaking on the other transforms too. It's okay to keep going back to transforms and messing about with them some more. 

So, I've moved the fx, and messed about with xform 2's post-transform, so what I now have is this:

2017-06-14 16 50 12-Editor by Holmes-JA

Now, I could stop here, mess about with the colours, and start my render, BUT I want to show you another thing I might try. 

Let's go back to xform 3, with the ngon. 

Let's see what happens if I clear it, and pick a different variable.

2017-06-14 16 53 14- by Holmes-JA

Now this, this I like. Save. 

2017-06-14 16 58 20- by Holmes-JA

Another possibility. 

So, what I've finally ended up with is this:

2017-06-14 17 04 51- by Holmes-JA

I like this a lot, and this is the piece I want to render. And there we have it! All that's left to do is colour it. Now you can move it over into Chaotica for colouring, or keep it right here in Apophysis, whichever you prefer. I'm staying in Apo because I am stuck in my ways. When it comes to doing the colours, I try and pick 10 possible gradients to use, and whittle down the versions until I find the one I like best. 

You can also go into the colour tab of each transform and fiddle with it, but I like the colour spread already so I won't touch it.

Insert muzak while I mess about with gradients

And this is what I finally end up with:

Tempered In The Heart Of A Star by Holmes-JA


So, it's a pretty easy process, but there's lots of fun to be had. This is relaxing fractalling, not the kind that makes you want to tear your hair out because Xaos won't play nice. I could have taken this even further by adding transforms, but I figured it'd be best to keep it simple for today. 

Happy tweaking!

I hope you are all having a wonderful weekend - sun is finally coming out here in the UK and looks to be turning out to be a nice - almost summers day :)


For my feature today i decided to focus on an artist.

I'm sure :icondragonfiretoo: needs no introductions. Alois has a style that is so amazingly unique and distinctive, with many having an intriguingly surreal, almost 'Daliesque' feel to them ;)

He is a dab hand at many 3D programs including MB3D, Bryce, Mandelbulber, Vue, Blender....

And if you have a wonder through his gallery he is also an excellent photographer and abstract painter!

His work speaks volumes for itself so i will now shut up and show you some fantastic examples from his gallery. Please visit this artist and show him your support :hug:



In these two pieces her has seamlessly combined various programs:

:iconpoca2hontas:


This is kind of a continuation of my previous journal about the flat plane type of heightmap. So this will cover the sphereheightmap. I'm going to start off with the same image we ended with previously. It already has the brick floor made with the standard HeightMapIFS formula in position 1. Those parameters are at the end of this tutorial. Let's have at it!

As I mentioned before, I prefer to place heightmaps, sphere heightmaps and dIFspheres in the first formula slot, because in my work I am much more apt to add extra escapetime formulas to the end of my formula string. Also as I said before, I usually leave an empty formula slot in position Fo.1. (Formula slot 1) so I am prepared to use a heightmap if I decide to at some later time in the creation process. Normally I never use more than one dIFS formula, so the one empty slot works well. But in this case, I have already filled Fo.1 with the HeightMapIFS that creates the brick floor. So there are two choices here. We can simply replace the HeightMapIFS (found in the first dIFS column) with the SphereHeightMap (found in the second dIFS column) and we would be ready to proceed. Or we can insert the SphereHeightMap before, or after the HeightMapIFS.

If you add the SphereHeightMap and use it with the HeightMapIFS, there are a few other things you have to do. Please load the first set of parameters included below. Hit the calculate 3d button and you will see the starting image with the brick floor. See below.

1 by HalTenny2 by HalTenny  3 by HalTenny



First you have to select the Amazing Surf formula in position Fo.2. Then right click on the Fo.2 tab. A popup appears. In the popup, select "Shift formulas 2 to 5 a position to the right." (#2 red box above) I think it should say "2 through 6" instead, but it doesn't matter. Doing this will shift formulas 2-6 to the right, and now formula slot Fo.2 will be empty, and you can put the SphereHeightMap there. You also have to change where the second part of the hybrid starts, so you have to change that # from 2 to 3. (# 1 red box) And lastly, you have to change the Max iterations for hybrid 1 from 1 to 2, because there are now 2 different dIFS formulas. (#4 red box) You may also want to change the DE combinate mode (#3 red box), and as a matter of fact, we are going to do that too. However, we aren't going to use the two heightmaps together in this tutorial. But I did want to show you how in case you want to do that in the future. So don't make any of the changes I just explained to you. Load the first set of parameters at the end of the tutorial, and simply replace the HeightMapIFS with the SphereHeightMap . Then change the DE combinate mode (red box #3 in first image) to Min nlin. Your formula window should match the second image above. And your fractal should look like the third image.

You can see that the brick heightmap is gone, but where the heck is the sphere from the SphereHeightMap formula? Well we have to find it, just like we had to find the HeightMapIFS  in the last tutorial. The problem is that you can't always find the sphere as easily as the HeightMapIFS. To make it easier, set your map number to zero in the SphereHeightMap Map nr field. Then zoom out and look for a plain sphere. See below.

5 by HalTenny  4 by HalTenny  

Above you can see I changed the map number to zero in the SphereHeightMap formula, and I have zoomed out and found the sphere. Now if you can see the sphere, you can obviously move it fairly easily. You use the X, Y, and Z offset values to do that. But believe me, it takes some time to get it where you want it this way. And as a matter of fact, sometimes when you zoom out, you can't find the sphere at all. Luckily there is a much easier way to place the sphere where you want it. Undo your zoom so you are back at the original zoom position. (Just hit the back button in the main window and click calculate 3d.) See below.

6 by HalTenny  7 by HalTenny  

This is fairly easy, so don't get overwhelmed. This is the easy way to place a SphereHeightMap where you want it in an image. I want the sphere somewhere near the center of the upper structure area. 1) Select the cutting tab (red box) in the main window. 2) Click the Get values from image button (green box). 3) Click on your main window image where you want to place the sphere (Yellow box). When you do that, a bunch of numbers appear (in the blue box) in the X,Y, Z fields that indicate the exact coordinates you clicked on. 4) Transfer the X,Y,Z coordinates that now show in the cutting box in the main window to the corresponding X,Y,Z offset fields in the formula window for the SphereHeightMap formula (red box, second image). 5) After you have completed steps 1-4, it is important to deselect the check boxes of the cutting coordinates (orange box) in the main window! You don't want to cut the image, you only wanted to find those coordinates. After you have deselected the check boxes, if you are impatient, you can click calculate 3d. But you will be disappointed. A blank image will appear. This is because the SphereHeightMap still needs to be scaled. Load the parameters into the navi window. Click Parameters button in navi window. Now you still have a blank image. See below.

8 by HalTenny    

Through my experience, to save time, select the big adjustments setting in the navi window. (red box in first image) Now make sure you have the SphereHeightMap selected in the navi window (blue box) and scroll down until you can see the scale setting (green box). Grab the slider and move it to the left slowly. Eventually, you will see the sphere appear, and you can scale it roughly to the size you want. How about that. Not too bad after all was it? Now comes the fun part. We're going to use a 'head' map for the SphereHeightMap. The head model we're going to use was provided by Dortus Gunst but it seems to no longer be available. You will find it at the end of the journal. Download the image and save it to your map folder. The map number is 8004.  If you already have a map with the same number, you'll have to change the map number (of the head image) to a number that is not yet used in your map folder. Then you will have to change the map number in the parameters to match the new head image map number. I'm using map # 8004, yours may differ... You can also use a different 'head' map if you wish. Or a cat, or monster thing, whatever you want. See image below.

9 by HalTenny  10 by HalTenny  

So the reason you can't see the head shape yet is because the sphere is oriented to the origin front view like if the views were all reset. Our current view is rotated and off center etc. So we have to rotate the sphere with the sphere A,B,C rotation settings. Eventually, you will be rotating the head to your taste, but to save you time, just set the rotations A box to -90 degrees. It will look similar to the second image. In the second image you can see that the head is recessed instead of a normal profile. This can happen depending on how the height map was made. If the dark color is front and the light color is back, the head will be recessed. If the dark color is in the back and the light color forward, the head would be in profile as we want it. But we can fix that simply by adjusting the the horizontal scale setting. Just adjust the horizontal scale setting to a negative setting with the slider in the navi window. Set the adjustment setting (top right of navi window) to mid instead of big. See below.

11 by HalTenny  12 by HalTenny  

I'll explain a few more things to you, but that's the basics of placing a SphereHeightMap in your scene. From here it is a matter of shaping the head a little with the X and Y scale settings. I like a thinner head as a rule. Make additional adjustments to the horizontal scale setting. Additional rotation settings with the sphere A,B,C rotation settings. And also additional position adjustments with the X,Y,Z offset fields. I'm going to turn the head sideways a little, make it narrower, then rotate and move it back into the structure some. You may find you have to switch back and forth between the different adjustments settings, min, fine, mid, and big. I do it all the time. In the second image, you can see the changes I made. I also zoomed in a bit. To me, this is the most important part of placing the head shape, so that it interacts in an interesting way with your fractal form. You will always just adjust the positions to your own taste. There is one more setting that you can play with too. It basically controls how much effect the fractal structure has on the head SphereHeightMap. In the image above on the right, I have the Ds. setting set to 1. See below.

13 by HalTenny  14 by HalTenny  

In the red box in the first image above is the Ds setting in the formula window. A higher setting will disturb the head or SphereHeightMap more than a lower setting. On the right side image above I have changed the Ds setting from 1 to 0.1, and you can see the disturbance of the fractal structure is less. Set that to your own taste.

That's it! I'm burned out now. I've done three journals in the past week, and I am done. I hope this helps somebody. These journals take 4 to 6 hours to write up, proofread half a dozen times, and get it all uploaded. Yes, I would like a little bread with my wine... :) Feel free to comment and fave.

Fractal Scenery, a guest feature for :iconxtremefractals2: by :iconshadoweddancer:


I have long been fascinated by fractals that picture any kind of scenery.  They can be very abstract to realistic.  They may depict any possible Earth landscape, waterscape, or any planet imaginable.  Some fractal programs lend themselves to scenery, and with others it may be more difficult.  They may be entirely fractal or manipulated with photographic elements.  The variety is nearly endless.  I thought for this guest feature I would share some of the fractal scenery from my collection.   Enjoy the selection and have a good week everyone!  


Please show your support for these talented artists by +favloveing their work and visiting their galleries.
