Advanced techniques: Draw 3D graphics in the "TURTLE" library in Python
Overview:
In Python, a simple two -dimensional graphical drawing can be achieved by using the `Turtle` Library.However, for more complex graphics, such as 3D graphics, we need to use some advanced skills.This article will introduce how to use the `Turtle` Library in Python to draw 3D graphics, and at the same time explain the complete programming code and related configuration.
1. Environmental configuration:
Before the beginning, we need to ensure that our Python environment has been installed with the `Turtle` library.Run the following commands in the terminal to install the `Turtle` library:
pip install PythonTurtle
2. Import class library:
Import the `turtle` library so that we can use the drawing function it provides.
python
import turtle
3. Set 3D environment:
Before drawing 3D graphics, we need to set up a 3D environment.Since the `turtle` library is a two -dimensional painting gallery, we can simulate 3D effects by setting perspective projection.
python
turtle.setup(width=800, height=600)
turtle.screensize(800, 600)
turtle.setworldcoordinates(-400, -300, 400, 300)
Turtle.bgcolor ('Black') # Set background background as black
turtle.pensize (2) # Set the thickness of the drawing brush
TURTLE.Speed (10) # Set drawing speed
4. Draw 3D graphics:
In the `turtle` library, we can use some basic drawing commands to draw 3D graphics, such as` Forward () `,` Backward (), `left (),` right (), etc.
python
# Draw a cube
def draw_cube(size):
for i in range(4):
turtle.forward(size)
turtle.left(90)
turtle.left(45)
turtle.forward(size)
turtle.right(45)
turtle.backward(size)
turtle.left(45)
turtle.backward(size)
turtle.right(45)
turtle.left(45)
turtle.forward(size)
turtle.left(45)
turtle.backward(size)
turtle.right(45)
draw_cube (100) # Draw a cube with a side length of 100
The above code uses the drawing command in the `Turtle` library to draw a simple cube through circulation, movement and rotation.
5. Running program:
Run the above code in the terminal to generate a cube graphic with 3D effects.You can control the size of the cube by adjusting the parameters in the `Draw_cube ()` function.
Summarize:
By using the `Turtle` class library in Python, we can use some advanced techniques to draw 3D graphics.By setting the perspective projection and using the basic drawing command, we can simulate some simple 3D effects.By exploring more functions and possibilities of the `Turtle` class library, we can draw more complex 3D graphics.Hope this article helps you learn how to use the `Turtle` in Python to draw 3D graphics.
