ASCII Illusions using ncurses

svg This project consists of several ASCII animations created using the ncurses library in C. Each program creates a unique visual illusion in the terminal, utilizing various patterns, movements, and color effects. The illusions include spinning lines, falling characters (Matrix code rain), expanding circles, and zig-zag patterns.

Table of Contents

Features

  • Colorful animations: Each illusion incorporates vibrant colors using the ncurses library's color functionality.
  • Unique visual effects: Four different types of illusions provide varied visual experiences in the terminal.
  • Customizable delay: The animation speed can be easily adjusted.

Requirements

  • C compiler (GCC recommended)
  • ncurses library installed on your system

Installing ncurses on Ubuntu/Linux

sudo apt-get install libncurses5-dev libncursesw5-dev

Installing ncurses on macOS

brew install ncurses

Installation

  1. Clone the repository:
git clone https://github.com/rkstudio585/ASCII-Illusions.git
cd ASCII-Illusions
  1. Compile each illusion program using GCC:
gcc -o spinning_lines spinning_lines.c -lncurses -lm
gcc -o matrix_rain matrix_rain.c -lncurses -lm
gcc -o expanding_circles expanding_circles.c -lncurses -lm
gcc -o zigzag zigzag.c -lncurses -lm

Usage

Run each illusion program from the terminal:

./spinning_lines
./matrix_rain
./expanding_circles
./zigzag

Press Ctrl + C to exit any of the animations.

Illusion Descriptions

  1. Spinning Lines

Description: This illusion features lines radiating from the center of the screen, rotating in a circular motion. The colors of the lines change over time, creating a dynamic effect.

Mechanism: It uses trigonometric functions (sine and cosine) to calculate the line positions based on an angle that increments over time.

  1. Matrix Code Rain

Description: Inspired by the Matrix movie, this illusion simulates falling characters that randomly appear across the screen. The characters are ASCII symbols, creating a visually striking effect.

Mechanism: Random ASCII characters are printed in a loop with a specified probability, using the rand() function to control their appearance.

  1. Expanding Circles

Description: This program generates circles that expand outward from the center of the screen. As the circles grow, their colors cycle through a range of available colors.

Mechanism: The radius of the circles increases incrementally, and points along the circumference are calculated using trigonometric functions.

  1. Zig-Zag Illusion

Description: This animation creates a zig-zag pattern that shifts horizontally across the screen. The pattern changes color with each frame, producing a lively effect.

Mechanism: The zig-zag pattern is determined by modular arithmetic, and it moves across the screen by incrementing an offset value.
