# GraphiCore

A graphics library I built from scratch in C, working directly with the Linux framebuffer through POSIX system calls. No standard library dependencies - just pure system programming.

## What I Built

- Direct framebuffer manipulation for screen control
- Custom memory management and buffer handling
- Non-blocking keyboard input using `select()`
- Basic graphics primitives (pixels, rectangles, circles)
- Text rendering with a custom bit-mapped font system

## Technical Highlights

- Memory-mapped I/O for efficient screen updates
- Raw terminal mode control and state management
- Optimized circle drawing using midpoint algorithm
- Custom font rendering system
- Precise timing control with `nanosleep()`

## Sample Output

## Why It's Cool

This project was my deep dive into system programming. I learned how to:
- Work directly with hardware through system calls
- Manage memory at a low level
- Handle terminal states and input
- Implement efficient graphics algorithms

## Future Ideas

- Double buffering for smoother graphics
- Support for different color depths
- Anti-aliasing for shapes
- Basic animation support
