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 by simulating the idealized orbits of two planets. At discrete time intervals, a line is drawn from one planet toward the other, extending from 40% of the inner planet to 70% of the outer planet. The idea came from Professor McClure’s Dance of Earth and Venus. Another rose-inspired image is here.
import numpy as np
import matplotlib.pyplot as plt
t = np.linspace(0, 2*np.pi, 10000)
plt.figure(facecolor=None)
for xi, xo, yi, yo in zip(
np.cos(12*t), 1.5*np.cos(7*t),
np.sin(12*t), 1.5*np.sin(7*t),
):
x = np.linspace(xi, xo, 11)[4:8]
y = np.linspace(yi, yo, 11)[4:8]
plt.plot(x, y, '#9D00FF09')
plt.axis('equal')
plt.axis('off')
plt.show()
