# 2D-Line-Drawing-Algorithms-VectorLineRenderer
This project demonstrates the implementation of three fundamental line drawing algorithms in 2D space using SDL:
- Bresenham Line Algorithm
- Midpoint Line Algorithm
- Parametric Line Algorithm
## Project Structure
The project consists of two main files:
- `Algo.cpp`: Contains the `main` function which sets up the SDL environment and handles rendering and input.
- `Header.h`: Contains all the function implementations for line drawing, pixel drawing, clearing the back buffer, and handling input.
## Functionality
### Initialization
The program initializes SDL, creates a window and a renderer, and sets up the initial screen.
### Clearing the Back Buffer
The `ClearBackBuffer` function clears the screen to a specified color.
### Drawing Pixels
The `DrawPixel` function draws a single pixel at a given position with a specified color.
### Drawing Markers
The `DrawMarker` function draws a square marker of a specified size and color at a given position.
### Line Drawing Algorithms
The project implements three line drawing algorithms:
- **Bresenham Line Algorithm:** Efficiently draws lines using integer calculations.
- **Midpoint Line Algorithm:** Draws lines by determining the midpoint between two points.
- **Parametric Line Algorithm:** Draws lines using parametric equations.
### Random Line Drawing
When key 1, 2, or 3 are pressed, the program draws a random line of a specified color (red, green, or blue/purple) on the screen and marks the start and end points with yellow pixels.
### Sky of Stars
When key 4 is pressed, all lines are cleared, and the screen is filled with randomly placed white pixels, simulating a sky full of stars.
### Final Output

### Handling User Input
The `HandleInput` function captures keyboard input to draw lines or clear the screen based on the user's key presses.
## Setup
To set up the SDL library in Visual Studio, follow the instructions provided in this [YouTube tutorial](https://youtu.be/13AEnd8XB70?si=IXO8L4JBEZiY1018).
## How to Run
1. Clone this repository.
2. Set up SDL in your development environment.
3. Compile and run `Algo.cpp`.
