I wanted to create something for my mom’s birthday. Her name is Rosella, and her favorite color is purple, which inspired me to design an image with a rose motif.
Technical Implementation
The image is created using a variant of rose curves where the radius is also a function of the angle. The image uses 8 curves with radii chosen so that the curves are connected. The result is a single curve resembling an abstract rose. Another rose-inspired image is here.
import numpy as np
import matplotlib.pyplot as plt
x, y = [], []
t = np.linspace(2*np.pi, 0, 999)
for i in range(8):
r = np.cos((i+1/2)*t) + 2*i + 2
x.extend(+r*np.sin(t))
y.extend(-r*np.cos(t))
plt.figure(facecolor=None)
plt.plot(x, y, '#90f', linewidth=2)
plt.axis('equal')
plt.axis('off')
plt.show()
