noise's Issues

repeating 3d simplex noise?

I noticed that perlin 3d has the ability to repeat, and simplex 2d as well; would it be possible to add simplex 3d repeating?

Can't import noise from other directories

Heyo, I'm a bit of a python noob, so forgive me if I'm doing something wrong here. When I run python from the repo directory, I can import noise without a problem. When I go up a level, I get this:

import noise
Traceback (most recent call last):
File "", line 1, in
File "noise/init.py", line 12, in
from . import _perlin, _simplex
ImportError: cannot import name _perlin

It can find the noise script just fine, but the noise script can't find perlin and simplex files? Not sure what the fix is for this - it's probably pretty simple but I couldn't find anything on it.

Thanks!

cannot import name _perlin after running install.py successfully from master

README link to information on simplex noise is broken

The README links to supplemental information on simplex noise: http://zach.in.tu-clausthal.de/teaching/cg2_08/literatur/simplexnoise.pdf

This link is broken: accessing the URL 404s.

I dug around on the University of Bremen website (Schließlich sind Deutschkurse nützlich) and found what I think is the same document, but at a working URL: http://cgvr.cs.uni-bremen.de/teaching/cg_literatur/simplexnoise.pdf

However, even better than that, I think, is the annotated / corrected version from Stefan Gustavson himself, here http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf

How to randomize the noise?

Reading the code I found a commentary in simplex constructor, for new a pattern generation. However, every time I call the function with same parameters, the pattern is unchanged. How can I rerandomize the noise pattern?

So far, I tried to shift the window with a random value. Is it correct?
mnoise = [[snoise2(4.0*float(m+random)/float(nt),5.0*float(n+random)/float(nt),16) for m in range(nt)] for n in range(nt)]

Add inverse function

Hi there this module is great and I was thinking if it would be useful to add the inverse perlin function

seeding noise

would it be possible to see the noise? I'm using this for terrain generation and the ability to seed the pattern and end up with different variations would be nice (i.e. planet X doesn't have the same landmasses as planet Y). Currently I'm just offsetting the X and Y, but that feels.... kludgy.

i'm using python 3.7

Base in py_noise2 doesn't do anything

I was porting the code in pure python from the c++ for vnoise (numpy-accelerated vectorized pure python port https://github.com/plottertools/vnoise (it's about as fast as the pure c++ if you vectorized those calls)), and this base thing stuck out as a thing that does anything. It's hooked up to nothing.

It shows up 3 times. Once in declaration and twice in the documentation. 0 times in actual code.

ImportError: Error relocating .../_perlin.cpython-37m-x86_64-linux-gnu.so: grad2: symbol not found

Hello,
I'm trying to use the noise library from inside docker alpine.
Installing noise with pip is okay, but when I try to import it I get this error message :


Traceback (most recent call last):
  File "map_generator.py", line 1, in <module>
    import noise
  File "/usr/lib/python3.7/site-packages/noise/__init__.py", line 12, in <module>

ImportError: Error relocating /usr/lib/python3.7/site-packages/noise/_perlin.cpython-37m-x86_64-linux-gnu.so: grad2: symbol not found

Any idea on how to fix this ?

Hot to credit noise

Hi, thanks for sharing this code. I have used it in my research and would like to acknowledge it in my paper. I have just said "we used noise" and added a link to the repo. Let me know if you'd like something different, like a link to a Zenodo DOI.

I know the last commit was 2 years ago, but I thought I'd ask.

When using pip to install noise : sudo pip install noise , an error occured :

EDIT : It work with pip3 install but not with pip for the default version of python wich is 2.7 on my distrib, i suppose it work with sudo python3 setup.py install although i didn't try

IndexError

Today I try terrain generation with different seeds. so I write:

from noise.perlin import SimplexNoise
noise2 = SimplexNoise(hash('a')).noise2
print(noise2(0, 0))

But some error raise:

[Discussion] Adding type hints?

First of all, thanks for making your work available to all of us!

I'm currently working on adding type hints to a project that uses the noise package. Since most of the functions & methods in this package - especially the ones defined in extension modules - do not make use of Python's dynamic typing, it seems possible and useful to add type hints here, aswell.

PEP 561 defines how to distribute type information with a python package, the documentation for mypy gives a good summary:

Type hints can either be distributed inline with the python code, or
Type stub files can be distributed within the same package, or
a separate stub files package called <packagename>-stubs can be created

I'd be willing to do all the work.

If you are in favor of adding type hints to the noise package, which way would you prefer, inline or as stub files? If you're opposed to adding type hints, would you mind if I create a noise-stubs package and publish it to PyPI?

Add Tileable 2D Simplex Noise

Could you add a function to get Tileable 2D Simplex noise? (possibly noise2 to TileableNoise)

According to the following link, one can use 4D Noise for that: http://gamedev.stackexchange.com/a/23639

Thank you very much! :)

Can't import noise

Hello, I recently wanted to move and use pypy3 but when I want to import the nosie lib I got the same message as the isssue #21

the problem doesn't comes from pypy3 but still

"
Traceback (most recent call last):
File "", line 1, in
File "C:\pypy3.6-v7.3.0-win32\lib-python\3\noise_init_.py", line 12, in

ImportError: cannot import name '_perlin'
"

I tried moving files into my project, moving the noise directory to another location also try to install it with the setup.py but doesn't work too. And finaly I tried using the wheel to install the module but it won't work anyways.

btw I remember having problems using this lib to with classic python 3.7

i'm on windows 10
i use PyPy 7.3.0 with MSC v.1911 32 bit

sorry for the bad english

I tried to manually build the library with python setup.py install, yet it fails as the package distributed with pip doesn't have the C source code: it is shipped with the already compiled libraries!

System:

Python 3.5.2;
FreeBSD 10.3 RELEASE p4;
pip 8.1.2;
noise 1.2.2

Could you update the latest version to pypi?

I've noticed the latest version of the package is not uploaded to pypi - coming here as I've also had the issue with the segfault on signal.snoise4 function.

Would you mind uploading the latest version? Not sure if I can do anything myself here.

Thanks!

Where should the grad2 symbol in _perlin.so come from?

Is there a seed argument?

Hi, I wanted to use this library for a game and cant seem to find a way to pass a seed to it. I want to be able to generate a world based off of a seed that a player would pass in (this would let them make the same world again in the future by passing the same seed in). Is there a way to do this?
