Thoughts on rendering speedBased on a discussion I followed in JWF facebook group.
Basically, render speed depends on amount of calculations the software needs to do. To show how it works, I will perform two experiments. Each experiment consist of a serie of examples which produce visually same output, but are built in different ways.
In this experiment, we will see what happens when we:
mix up many transforms (variations)
add many linked transforms
add many pre_transforms or post_transforms
Params: Apo - Chaotica
example 1: default parameters with linked waves2
DE speed: 58.3
example 2: waves2 replaced with 10 waves2 transforms with same setup (I set the amount to 0.1 so they add up to 1 and produce same effect)
DE speed: 21.1
example 3: 10 linked linears added to the waves2 transform
DE speed: 14.4
example 4: 10 linear pre_affines are added to the waves2 transform
DE speed: 40.9
Cpow3 without overlapsAll the needed plugins can be found in Essential Plugin Pack
You need a shape with a hole of same shape in the middle (it doesn't really have to be in the middle, but that is trickier )
Cpow3_d is the ratio of the hole to the whole shape. For example, if the hole is a circle of radius 0.5 and the shape is a circle of radius 1, cpow3_d is 0.5 / 1 = 0.5. If the hole is a square of side 1, and the shape is a square of side 3, cpow3_d is 1 / 3 = 0.333333.
Cpow3_r is equal to 360 / (rotation of hole). Lets see a few examples:
1. A circle with a circular hole. In this case, the hole can be rotated any angle compared to main shape, and it will still remain the same. So cpow3_r can take any value without creating overlaps.
Wire-Gnarls: An Apo/Chaotica TrickSomeone in Discord asked me how I was getting the details on my gnarls lately, and I figured I'd just write a little thing about it
First off, you need Apophysis 7x and Chaotica.
You're first going to want to create a new blank flame.
In your Apophysis editor, you're going to clear all variations and set waves2 = 0.995. Then, set the transform weight to 50.
Next, we're going to tweak waves2's variables just like so:
You're going to want to experiment! This is not the only way to make a gnarl!
At this point, you're not going to see much going on. We'll fix this. Create transform 2, and leave it just as it is.
Rotate tx2 90 Degrees CCW (left).
Go back to tx1 and rotate
Moving elements of the fractalThis trick is useful for abstracts, and for multiple loop fractals.
Lets start with those parameters: Example params 1. The fractal looks like this:
Moving one transform
If you try moving a transform around, it will change all the structure. What if you want to move a transform without changing the pattern?
Lets say you want to move transform 2 of the example params. Do the following:
Add a linked transform to transform 2.
Set transform 2 opacity to 1, and linked transform opacity to 0.Move the post affine of transform 2: for example, 1 unit right and 0.5 unit up.Move the linked transform: 1 unit left and 0.5 unit down.
To make it work, make sure the post affine and the linked transform shifts cancel each other.
You should have this: Example params 2
Same trick, just usin
Cancelling distortion with pre and post affinesA small trick that some people may find useful.
The basic idea is to use post affine (post transform in Apo) to create some distortion, and then use the affine to "cancel" this distortion.
Example 1: Hemisphere to ellipse
Suppose that you need an elliptic shape. As an example, I will use the final (camera) transform and apply it on the picture below:
First, add a hemisphere final transform. It looks like a circle, not like an ellipse:
Now, go to the transform tab of the editor. Look at the post transform. Both X and Y values are 1. Change X value to 2. This will stretch the hemisphere:
Notice that the pattern is too stretched. To cancel that, change the X value of the transform (not post transform anymore) to 0.5 (which is inverse of 2 we used above). You shall have something like this:
