Cmatrix
cmatrix is a C-based terminal application and command line utility designed to simulate a scrolling digital rain effect. It functions as a CLI visual animation tool that renders falling code patterns and custom text displays within a terminal emulator.
The application provides options for visual style customization, allowing users to modify color schemes, font styles, and character sets. It includes animation speed control to adjust the rate of falling characters and supports rendering specific custom messages in the center of the screen during the animation.
Features
- Terminal Animations - A command line application that renders a scrolling screen of characters mimicking a digital rain effect.
- Terminal Visual Effects - Creates a scrolling digital rain animation in the terminal for aesthetic and atmospheric purposes.
- Particle Effect Simulations - Simulates the movement of a large quantity of individual characters to create a falling digital rain effect.
- CLI Visual Animation Tools - Functions as a CLI tool for displaying customizable falling code patterns and custom text messages.
- Character Grid State Tracking - Maintains a grid of characters and their vertical positions to calculate the movement for every animation frame.
- Native C Terminal Applications - Implements a lightweight utility written in C to manipulate terminal output for visual effects.
- Terminal and Command-Line Environments - Provides a customizable tool for personalizing the terminal environment with visual animations and schemes.
- ANSI Escape Sequence Renderers - Implements an engine that generates raw ANSI escape codes to handle text color and formatting for the digital rain effect.
- Ncurses-Based Rendering - Utilizes the ncurses library to directly control screen coordinates and colors within the terminal emulator.
- Random Number Generation - Generates pseudo-random values to determine character sequences and drop positions for organic visual effects.
- Fixed-Timestep Loops - Controls the animation speed using a fixed-timestep loop to ensure consistent falling rates regardless of system performance.
- Aesthetic Display Interfaces - Mimics high-tech movie interfaces by adding dynamic visual elements to the terminal display.
- Double Buffering - Uses an off-screen buffer to render interface updates before flushing to the terminal to prevent screen flickering.
- Frame Rate Controls - Allows users to adjust the update delay between screen refreshes to control how fast characters fall.
- Visual Style Customization - Provides mechanisms to modify the color scheme, font styles, and character sets for a customized visual appearance.
- Visual Scripts - Terminal matrix animation.
