Program Code – Understanding the Role of Curves in Computer Graphics

import numpy as np
import matplotlib.pyplot as plt

# Function to calculate the points on a Bezier curve
def bezier_curve(control_points, num_points=100):
    '''
    Generate a Bezier curve from control points.
    
    :param control_points: A list of tuples (x, y) representing control points.
    :param num_points: Number of points to generate on the curve.
    :return: Points on the Bezier curve.
    '''
    n = len(control_points) - 1
    points = np.array(control_points)
    curve = np.zeros((num_points, 2))
    
    for t_i in range(num_points):
        t = t_i / (num_points - 1)
        curve[t_i] = sum(
            scipy.special.comb(n, i) * (1 - t)**(n - i) * t**i * points[i]
            for i in range(n + 1)
        )
    
    return curve

# Control points for the curve (Change them to experiment)
control_pts = [(0, 0), (1, 2), (3, 3), (4, 1)]

# Generates the Bezier curve points
curve_points = bezier_curve(control_pts)

# Plotting the control points and the curve
plt.figure(figsize=(10, 5))
plt.plot(*zip(*control_pts), 'ro-', label='Control Points')
plt.plot(curve_points[:, 0], curve_points[:, 1], 'b-', label='Bezier Curve')
plt.title('Bezier Curve Implementation')
plt.legend()
plt.grid(True)
plt.show()

Code Output:

The output of this code would be a plot displaying a Bezier curve alongside its control points. The control points are connected by red lines and are marked with red dots. The Bezier curve is drawn in blue.

Code Explanation:

This program generates and plots a Bezier curve using a given set of control points.

1. The program begins by importing the necessary libraries: NumPy for numerical operations and Matplotlib for plotting the curve.
2. It defines a function, bezier_curve, which takes a list of control points and the number of points to calculate on the curve. Each control point is a tuple containing x and y coordinates.
3. Inside the function, it initializes the number of control points minus one (n) and an array curve which will store the calculated points on the curve.
4. It then calculates the points on the Bezier curve with a loop over the desired number of points. It uses Bernstein polynomials for this, represented with the binomial coefficient (scipy.special.comb) and powers of t.
5. The curve array is populated with the calculated points.
6. Control points are defined to demo the curve plotting.
7. The Bezier curve is generated using the bezier_curve function and the specified control points.
8. Finally, it plots the control points, the curve, and sets up the plot with a title, legend, and grid for better understanding and visualization of the curve’s construction.

The architecture of this function essentially breaks down the process of generating a Bezier curve into a calculation of intermediate points based on a linear interpolation of the control points. This process is iterated recursively, gradually building up the final curve.
