🎨 SDL3 Random Walk Lines

A simple generative art experiment built with SDL3 in C.
Multiple colored lines start from the center of the screen and perform a bounded random walk, creating evolving abstract patterns.

• Independent lines
• Random colors
• Bounded movement (no going outside window)
• Persistent drawing using a texture as canvas

🧠 How It Works

Each frame:

1. A random direction is chosen (X or Y axis)
2. The line moves either positive or negative
3. Boundary checks prevent leaving the screen
4. A line is drawn from old position to new position
5. Drawing accumulates over time on a texture

This creates a generative art random-walk effect.

🛠 Requirements

• MinGW (GCC) – for compiling the project
• SDL3 development library – included inside this repository (SDL/ folder)

🔨 Build

From project root:

mingw32-make

Or manually:

gcc src/main.c -ISDL/include -LSDL/lib -lmingw32 -lSDL3 -o main.exe

▶ Run

Make sure SDL3.dll is in the same directory as main.exe, then:

./main.exe
