while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # Drawing the terrain

    pygame.display.flip()
    clock.tick(60)  # Maintain 60 FPS

pygame.quit()

Code Output:

The window titled ‘Real-Time Terrain Generation’ will display a dynamic, colorized terrain map that evolves in real-time. The terrain colors will blend from white to different shades of blue, simulating the variations of altitude.

Code Explanation:

This program generates a terrain in real-time using Perlin noise, created through the Pygame library in Python.

1. We start by importing necessary modules. Pygame for rendering, noise for generating Perlin noise, and numpy for numerical operations.
2. Screen dimensions are set and color constants are defined.
3. Pygame is initiated and a window is created.
4. The generate_terrain function creates a 2D array representing the terrain. The noise library generates Perlin noise for each pixel. The result is normalized to bring the values between 0 and 1.
5. Then, the draw_terrain function maps the normalized terrain values to a color scale between white and blue and renders this on the screen.
6. In the main loop, we check for the QUIT event to allow closing the window. The terrain is redrawn each frame.
7. The screen is updated with pygame.display.flip() and the game tick is maintained at 60 FPS with clock.tick(60).
8. This results in the real-time rendering of terrain on the screen.

Keeping the rendering simple allows readers to focus on the terrain generation logic. By manipulating the scale and noise parameters, different terrain features can be simulated. The use of Perlin noise creates more natural-looking terrain by providing smooth, continuous variations in the height map.
