🎨 Computer Graphics – DDA Line & Midpoint Circle Drawing

This JavaFX project demonstrates two classic computer graphics algorithms:

1. DDA Line Drawing Algorithm
2. Midpoint Circle Drawing Algorithm

These algorithms are used to draw straight lines and perfect circles pixel-by-pixel on a canvas, which is a foundational topic in computer graphics.

💡 Description

This JavaFX application draws a line using the DDA algorithm and a circle using the Midpoint Circle Drawing algorithm on a black canvas.
It uses pixel-level plotting via GraphicsContext.fillRect() to simulate low-level drawing, just like what happens in OpenGL or raster graphics.

🧠 Algorithms Used

✅ DDA Line Drawing

• Calculates dx and dy between two points
• Determines the number of steps based on the greater value
• Increments x and y gradually using floating-point arithmetic

✅ Midpoint Circle Drawing

• Uses symmetry of a circle to plot 8 points per iteration
• Efficient integer-based algorithm
• Avoids floating-point arithmetic for speed
