Write, compile and run a Java program to draw a line using Bresenham’s algorithm and Java OpenGL wrapper library (JOGL)

Bresenham line drawing Algorithm:

Input: point₁ = (x₁, y₁) = (-2, 3) , =  ( x₁, y₁) = (8, 10)

Step 1: Start the program.

Step 2: Initialize the graphics mode using init graph function.

Step 3: Accept the input at starting and endpoint of the line to be drawn.

Step 4: Load (x_i, y_i) into the frame buffer to be plotted as a first point.

Step 5: Calculate the constants delta x, delta y, 2delta y - 2delta x and obtain the first decision parameter  p₀= 2delta y - 2delta x

Step 6: At each  along the line starting at k = 0 perform the following test:

·       If P_k < 0, then

o      the next point is (X_k+1 ,y_k  ),

o     p_k+1= p_k + 2delta y

·      If p_k >= 0 , then

o      the next point to the plotted is (x_k+1 , y_k+1),

o     p_k+1 =p_k+   2delta y - 2delta x

Step 7: Repeat the process until the end point of the line to be drawn is encountered.

Step 8: Stop the program.
