LineDream 0.1.4

A creative coding library...

LineDream is a generative art library for Python. It is heavily influenced by P5 and Processing. However, it takes a more object oriented approach, with less global states.

Currently, output files are saved as SVGs. There is not yet support for a draw loop - it is single frame output, but you could use a loop to simulate this.

The library was originally created to make art for a pen plotter, however, the inner object structure could be applied to many different rendering platforms.

Installation

pip install LineDream

Example

import random
from LineDream import Path, Canvas, Rectangle, Square, Ellipse, Point, Circle, CircleMath, TextPaths

Canvas.width=900
Canvas.height=500
Canvas.background_color='black'

for pp in range(100):
	x = random.randint(0, Canvas.width)
	y = random.randint(0, 400)

	coords = (x,y)
	p = Point(*coords)

	p.stroke_color= 'white'

c_size = 180

circle_center = Canvas.width/2, Canvas.height+c_size/2
c = Circle(*circle_center, 180)
c.stroke_color='white'

c = Circle(*circle_center, 200)
c.stroke_color='white'

c = Circle(*circle_center, 220)
c.stroke_color='white'

long=True
for degrees in range(360,180,-10):

	dist_from_circle = 250

	line_len = 40
	if long:
		line_len = 100
		long=False
	else:
		long=True

	d_x_s, d_y_s = CircleMath.distance_to_coords(degrees, dist_from_circle)
	x1 = circle_center[0] + d_x_s
	y1 = circle_center[1] + d_y_s

	d_x, d_y = CircleMath.distance_to_coords(degrees, dist_from_circle + line_len)
	x2 = circle_center[0] + d_x
	y2 = circle_center[1] + d_y

	Path([(x1,y1), (x2,y2)], stroke_color='white')

# EXPERIMENTAL
tt = TextPaths('LineDream', kerning=10, stroke_color='white', stroke_width=2)
tt.transform(100, 100)
tt.scale(1.4)

Canvas.save(f'example.svg')

Todos:

• Integrate TextPath with Hershey (initial implementation complete)
• Convert all vertexes to Numpy arrays
• Add .rotate()
• Add .scale() (partially implemented in some classes)
