infinite-3d-floor-python3

A personal challenge creating yet another demoscene'ish program in Python3, showing off classic Amiga demoscene-like "infinite floor" graphics effect, scrolling text with water drop-shadow and a bouncing Boing Ball, On Linux :P

Made with Python3 using PyGame that implements a perspective checkered spinning tunnel, Bresenham's Line Algortihm moving starfield and a isometric polygon cube moving floor. Now with a soundbyte bgm loop!

Should work on any Linux distribution that has Python3 + PyGame.

Sound loop courtesy of k!M.

Required:

sudo apt-get install python3 python3-pygame python3-numpy

Usage:

$ ./infinite-3d-floor.py -f / --fullscreen /  -w 1280 -h 720 / --width 1280 --height 720

How:

• Perspective Floor: map the 2D screen pixels of the bottom half of the screen into 3D world space using a depth divisor (Distance $Z = \frac{\text{Camera Height}}{Y}$).
• Rotozoomer Overlay: A smaller, floating texture (like a logo or text) spinning and scaling smoothly across the screen, rendered directly into the pixel buffer on top of the 3D floor.
• Boing Ball: The "Boing Ball" is the ultimate crown jewel of the Amiga demoscene! To do it justice, we won’t just move a flat 2D sprite around. We will use NumPy to calculate a true 3D raycasted sphere with a wrapping checkerboard texture that dynamically rotates and depth-shades itself every single frame.
