QUESTION

Applying Perlin noise to plane multiple times/ sphere

Asked 2021-Aug-10 at 21:36

I have some questions regarding the Perlin noise and the pv.sample_function in general.

How would you go about applying Perlin noise to a sphere? I would like to have a little bit disformed sphere.
Can you apply Perlin noise to a mesh (sphere/plane) multiple times? I would like to have a plane with some rough 'waves' and high detailed noise on top of them (thus having big waves with little waves in them).
What exactly does the third parameter in the frequency do? After playing around with some values I haven't noticed how it affected the noise.

These are the two different frequencies/Perlin noises that I would like to apply to one plane. Additionally, it shows the plane they respectively create.

Let me answer your questions in reverse order for didactical reasons.

What exactly does the third parameter in the frequency do? After playing around with some values I haven't noticed how it affected the noise.

You didn't see an effect because you were looking at 2d samples, and changing the behaviour along the third axis. The three frequencies specify the granularity of the noise along the x, y and z axes, respectively. In other words, the generated implicit function is a scalar function of three variables. It's just that your sampling reduces the dimensionality to 2.

Frequency might be a surprising quantity when it comes to spatial quantities, but it works the same way as for time. High temporal frequency means short oscillation period, low temporal frequency means long oscillation period. High spatial frequency means short wavelength, low spatial frequency means long wavelength. To be specific, wavelength and frequency are inversely proportional.

So you'll see the effect of the third frequency when you start slicing along the z axis:

QUESTION

Multiprocessing only utilizing a single core

Asked 2021-May-27 at 10:24

I'm trying to create a FBM texture using the module perlin-noise, but it takes a very long time to execute. I've implemented multiprocessing, only to find that the program was still running off a single core. I've tried looking for other people with the same problem, but most threads were 7+ years old and / or involved problems and solutions related to different OSs.

My OS is Windows 8.1, I have a quad-core CPU, and I'm running Python 3.9.2

Here is the program:

Reason why it only use one Process is simple. You only passed 1-length list in Pool.map.

What Pool(n).map(function, iterable) does is, applying provided funtion to each element of provided iterable(in this case, list) with n number of worker processes.

Since you only have 128 in nums it's only creating one task thus no other processes are ever used.

Proper usage would look like this:

Surface.blit wants a rect as area argument. You pass a string.

What you could do is create a map to translate the strings to the right rects that you already defined, something like this:
