Samila

Overview

Samila is a generative art generator written in Python, Samila let's you create arts based on many thousand points. The position of every single point is calculated by a formula, which has random parameters. Because of the random numbers, every image looks different.

Usage

Magic

>>> import matplotlib.pyplot as plt
>>> from samila import GenerativeImage
>>> g = GenerativeImage()
>>> g.generate()
>>> g.plot()
>>> plt.show()

Basic

>>> import random
>>> import math
>>> def f1(x, y):
    result = random.uniform(-1,1) * x**2  - math.sin(y**2) + abs(y-x)
    return result
>>> def f2(x, y):
    result = random.uniform(-1,1) * y**3 - math.cos(x**2) + 2*x
    return result
>>> g = GenerativeImage(f1, f2)
>>> g.generate()
>>> g.plot()
>>> g.seed
188781
>>> plt.show()

Projection

>>> from samila import Projection
>>> g = GenerativeImage(f1, f2)
>>> g.generate()
>>> g.plot(projection=Projection.POLAR)
>>> g.seed
829730
>>> plt.show()

Supported projections : RECTILINEAR, POLAR, AITOFF, HAMMER, LAMBERT, MOLLWEIDE and RANDOM
Default projection is RECTILINEAR

Range

>>> g = GenerativeImage(f1, f2)
>>> g.generate(start=-2*math.pi, step=0.01, stop=0)
>>> g.plot()
>>> g.seed
234752
>>> plt.show()

Color

>>> g = GenerativeImage(f1, f2)
>>> g.generate()
>>> g.plot(color="yellow", bgcolor="black", projection=Projection.POLAR)
>>> g.seed
1018273
>>> plt.show()

Supported colors are available in VALID_COLORS list
color and bgcolor parameters supported formats:
1. Color name (example: color="yellow")
2. RGB/RGBA (example: color=(0.1,0.1,0.1), color=(0.1,0.1,0.1,0.1))
3. Hex (example: color="#eeefff")
4. Random (example: color="random")
5. Complement (example: color="complement", bgcolor="blue")
6. Transparent (example: bgcolor="transparent")

⚠️ Transparent mode is only available for background

Regeneration

>>> g = GenerativeImage(f1, f2)
>>> g.generate(seed=1018273)
>>> g.plot(projection=Projection.POLAR)
>>> plt.show()

NFT.storage

Upload generated image directly to NFT.storage

>>> g.nft_storage(api_key="YOUR_API_KEY")
{'status': True, 'message': 'FILE_LINK'}

Save image

Save generated image

>>> g.save_image(file_adr="test.png")
{'status': True, 'message': 'FILE_PATH'}

Save generated image in higher resolutions

>>> g.save_image(file_adr="test.png", depth=5)
{'status': True, 'message': 'FILE_PATH'}

Save data

Save generated image data

>>> g.save_data(file_adr="data.json")
{'status': True, 'message': 'FILE_PATH'}

So you can load it into a GenerativeImage instance later by

>>> g = GenerativeImage(data=open('data.json', 'r'))

Data structure:

{
  "plot": {
    "projection": "polar",
    "bgcolor": "black",
    "color": "snow",
    "spot_size": 0.01
  },
  "matplotlib_version": "3.0.3",
  "data1": [
    0.3886741692042526,
    22.57390286376703,
    -0.1646310981668766,
    66.23632344600155
  ],
  "data2": [
    -0.14588750183600108,
    20.197945942677833,
    0.5485453260942901,
    -589.3284610518896
  ]
}

Save config

Save generated image config. It contains string formats of functions which is also human readable.

>>> g.save_config(file_adr="config.json")
{'status': True, 'message': 'FILE_PATH'}

So you can load it into a GenerativeImage instance later by

>>> g = GenerativeImage(config=open('config.json', 'r'))

Config structure:

{
    "matplotlib_version": "3.0.3",
    "generate": {
        "seed": 379184,
        "stop": 3.141592653589793,
        "step": 0.01,
        "start": -3.141592653589793
    },
    "f2": "random.uniform(-1,1)*math.cos(x*(y**3))+random.uniform(-1,1)*math.ceil(y-x)",
    "f1": "random.uniform(-1,1)*math.ceil(y)-random.uniform(-1,1)*y**2+random.uniform(-1,1)*abs(y-x)",
    "plot": {
        "color": "snow",
        "bgcolor": "black",
        "projection": "polar",
        "spot_size": 0.01
    }
}

Mathematical details

Samila is simply a transformation between a square-shaped space from the Cartesian coordinate system to any arbitrary coordination like Polar coordinate system.

Example

We have set of points in the first space (left square) which can be define as follow:

And bellow functions are used for transformation:

>>> def f1(x, y):
    result = random.uniform(-1,1) * x**2 - math.sin(y**2) + abs(y-x)
    return result
>>> def f2(x, y):
    result = random.uniform(-1,1) * y**3 - math.cos(x**2) + 2*x
    return result

here we uses Projection.POLAR so later space will be the polar space and we have:

>>> g = GenerativeImage(f1, f2)
>>> g.generate(seed=10)
>>> g.plot(projection=Projection.POLAR)

Samila can be used online in interactive Jupyter Notebooks via the Binder or Colab services! Try it out now! :
