Use python to draw code examples of moon and moon cakes.

This article mainly introduces "using python to draw the moon and moon cake code examples". In the daily operation, I believe that many people have doubts about using python to draw the moon and moon cake code examples. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "using python to draw the moon and moon cake code examples". Next, please follow the editor to study!

One,? The moon

Two,? Snowflake moon cake

One,? The moon

Import libraries matplotlib and numpy for direct use as tools.

From mpl_toolkits.mplot3d import Axes3Dimport matplotlib.pyplot as pltimport numpy as np

Overall Arrangement

Create a long × wide canvas size

Fig = plt.figure (figsize= (1010))

Layout of 3D viewing angle

Ax = fig.add_subplot (121, projection='3d')

Generate the data of the isometric sequence and draw a sphere

X = np.linspace (0,2 * np.pi) y = np.linspace (0,2 * np.pi) x1 = 10 * np.outer (np.cos (x), np.sin (y)) y1 = 10 * np.outer (np.sin (x), np.sin (y)) z = 10 * np.outer (np.ones (np.size (x1)), np.cos (y1)) ax.plot_surface (x1, y1, z, color='yellow')

At this time, we found that there was only one moon, so we planned to draw the second moon and form a pair.

Ax = fig.add_subplot (122,100) x = np.linspace (0,2 * np.pi) y = np.linspace (0,np.pi, 100) x1 = 10 * np.outer (np.cos (x), np.sin (y)) y1 = 10 * np.outer (np.sin (x), np.sin (y)) z = 10 * np.outer (np.ones (np.size (x1)), np.cos (y1) ax.plot_surface (x1, y1, z) Color='r')

It's all right ~ ha!

Two,? Snowflake moon cake

To import the required libraries, most of them are written by turtle.

Import turtleimport time

Let's draw a bottom yellow cake as the bottom.

Def circle (): fillX_y (0,0) turtle.color ("# F0E68C") for _ in range (30): turtle.left (12) turtle.begin_fill () turtle.forward (230) turtle.circle (25,180) turtle.goto (0,0) turtle.left (180) turtle.end_fill () time.sleep

Since it is a snowflake moon cake, there should be snowflakes. Next, let's draw snowflakes.

Koch curve is used to draw snowflakes. To change the degree of bending.

Def koch (size, n): # defines a curved line to make it angular if n = 0: turtle.fd (size) else: for angle in [0,60,120,60]: # change it at a reasonable angle each time turtle.left (angle) koch (size / 3, n-1)

Because I'm going to draw eight and add colors, so colorful snowflakes ~

If a = 1: turtle.color ("black") # controls the brush color elif a = = 2: turtle.color ("purple") elif a = = 3: turtle.color ("blue") elif a = = 4: turtle.color ("Cyan") elif a = = 5: turtle.color ("green") elif a = = 6: turtle.color ("yellow") elif a = 7: turtle.color ("orange") elif a = 8: turtle.color ("red")

Since it is nested by eight snowflakes, a proportionally scaled package is required.

Turtle.penup () turtle.goto (- 200 * (4 / 7) * * (s-n), 100 * (4 / 7) * * (s-n)) # each time it is necessary to expand or shrink turtle.pendown () turtle.pensize (2) level = 5koch (400 * (4 / 7) * (s-n), level) # is a trial # that cannot exceed the set range of setup Otherwise, turtle.right (120,400) koch (400 * (4 / 7) * * (s-n), level) turtle.right (120) koch (400,400 * (4 / 7) * * (s-n), level) # Note here koch has to turn the angle turtle.right (120) turtle.hideturtle () # Hidden brush flower (n-1)

Effect picture! Ah ha! It's a snowflake moon cake!
