Ultra Fractal Tutorial - The Making of "Lords of Arrakis"
Part 7. Creating the "space ring" layer.

Page 3. Adjust location.

Step 6. Magnify image.

We'll develop the "space ring" layer by altering it using the five Location tab parameters: Magnification, Rotation Angle, Center (X, or real, and Y, or imaginary, values), Stretch, and Skew.

Originally I developed these quantities by key-and-mouse drags, observing as the figure changed. I'll give you the values that I determined in this way for you to type, or copy and paste, into the Location tab parameters.
 

A. With the "space ring" layer highlighted, click on the Location tab.

 
Here's the present undeveloped "space ring" layer corresponding to the current settings shown above:

 
First, we'll double the Magnification of the image, from a value of approximately "1" to a value of approximately "2":
 

B. Type, or copy and paste, the following number into the Magnification parameter of the Location tab: 2.0627438

 
The magnified image should look like this:

 
Next we'll rotate the image through an angle of approximately 30 degrees.
 


Step 7. Rotate image.
 
A. Type, or copy and paste, the following number into the Rotation Angle parameter: 112.1874

 
The rotated image should look like this:

 
Notice that the Lake transformation, which this layer inherited from the "lords 1" layer, continues to function in a vertical manner even after rotation of the image.

As a next step, we'll pan the image slightly upward and to the right.
 


Step 8. Pan image.
 
A. Type, or copy and paste, the following number into the Center (Re) parameter (the X value): -2.774476012

Then type, or copy and paste, the following number into the Center (Im) parameter (the Y value): -0.98381689175

 
The panned image should look like this:

 
Now, as the first of the two deforming operations, we'll apply some stretch.

 


Step 9. Stretch image.
 
A. Type, or copy and paste, the following number into the Stretch parameter: 2.8272

 
The stretched image should look like this:

 
A good-looking space image is emerging now, in the upper right-hand corner.

The final alteration to the developing "space ring" image will be a skew.

 


Step 10. Skew image.
 
A. Type, or copy and paste, the following number into the Skew Angle parameter: -58.0322

 
The skewed image should look like this:

 
This is what I was looking for.

All that is required now is to trim a little off of the bottom.
For this, we will use the Clipping transformation.
