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

Basic

>>> import random
>>> import math
>>> import matplotlib.pyplot as plt
>>> from samila import GenerativeImage
>>> 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 and MOLLWEIDE
• Default projection is RECTILINEAR

Range

>>> g = GenerativeImage(f1,f2)
>>> g.generate(start = -2*math.pi,step=0.1,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 support color name and RGB/RGBA formats

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': 'Everything seems good'}

Save

Save generated image

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

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)
