import pygame
import math
Set up the display
pygame.init()
width = 500
height = 500
display = pygame.display.set_mode((width, height))
pygame.display.set_caption("3D Cube")
Define the vertices of the cube
vertices = [[-1, -1, -1],
[1, -1, -1],
[1, 1, -1],
[-1, 1, -1],
[-1, -1, 1],
[1, -1, 1],
[1, 1, 1],
[-1, 1, 1]]
Scale the vertices
scale_factor = 2
vertices = [[scale_factor * x, scale_factor * y, scale_factor * z] for x, y, z in vertices]
Define the edges of the cube
edges = [[0, 1],
[1, 2],
[2, 3],
[3, 0],
[4, 5],
[5, 6],
[6, 7],
[7, 4],
[0, 4],
[1, 5],
[2, 6],
[3, 7]]
Define the center of the Pydroid 3 screen
center = [width//2, height//2]
Define the angle of rotation
angle = 0
Define the main game loop
while True:
Handle events
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
Clear the screen
display.fill((255, 255, 255))
Rotate the vertices
sin_a = math.sin(angle)
cos_a = math.cos(angle)
rotated_vertices = []
for vertex in vertices:
x = vertex[0]
y = vertex[1]
z = vertex[2]
Rotate around the x-axis
y, z = y * cos_a - z * sin_a, y * sin_a + z * cos_a
Rotate around the y-axis
x, z = x * cos_a - z * sin_a, x * sin_a + z * cos_a
Rotate around the z-axis
x, y = x * cos_a - y * sin_a, x * sin_a + y * cos_a
Project onto the 2D screen
f = 200 / (z + 4)
x, y = x * f, y * f
Shift the center of the cube to the center of the screen
x, y = x + center[0], y + center[1]
rotated_vertices.append((x, y))
Draw the edges
for edge in edges:
start = rotated_vertices[edge[0]]
end = rotated_vertices[edge[1]]
pygame.draw.line(display, (0, 0, 0), start, end, 2)
Update the angle of rotation
angle += 0.01
Update the display
pygame.display.update()
