🔗 From Web Demo to Python Code

The interactive web demo uses the same mathematical principles we'll implement in Python. Here's how they connect:

🌐 Web Demo (JavaScript)

// Torus equations in JavaScript
x = (R + r * cos(v)) * cos(u)
y = (R + r * cos(v)) * sin(u)  
z = r * sin(v)

🐍 Our Python Version

# Same torus equations in Python
X = (R + r * np.cos(V)) * np.cos(U)
Y = (R + r * np.cos(V)) * np.sin(U)
Z = r * np.sin(V)

Key Insight: The math is identical! Only the syntax changes between languages. This teaches you that mathematical concepts are universal - once you understand the math, you can implement it anywhere.

Parametric Equations

Our art uses parametric equations - mathematical formulas where x and y coordinates are calculated using a parameter (in our case, time 't').

Key Mathematical Functions:

  • math.sin() and math.cos() - Create wave patterns and circular motions
  • math.sqrt() - Calculate distances from center
  • math.atan2() - Find angles for polar coordinates
  • Time parameter 't' - Makes the pattern animate and evolve

Why These Patterns Are Beautiful

The patterns we create follow mathematical principles found in nature:

  • Symmetry - The formulas create naturally symmetric patterns
  • Fractals - Self-repeating patterns at different scales
  • Golden Ratio - Mathematical proportions that are pleasing to the eye
  • Harmonic Motion - Sine and cosine create smooth, flowing curves

🎯 Try These Experiments

🔬 Experiment 1: Modify the Mathematics

Try changing these values in the mathematical formula:

  • Change k = x / 8 - 25 to k = x / 12 - 30
  • Modify d = 5 * math.cos(...) to use different multipliers
  • Try math.sin(d * 6 - t) instead of math.sin(d * 4 - t)

Question: How do these changes affect the pattern?

🌈 Experiment 2: Create Your Own Pattern

Design your own mathematical pattern function:

def my_pattern(self, x, y, t):
    """Your custom mathematical pattern"""
    # Try creating patterns with:
    # - Different numbers of petals: math.sin(angle * 6)
    # - Spiral effects: r + t * 0.1
    # - Wave combinations: math.sin(x*0.1) + math.cos(y*0.1)
    
    center_x, center_y = 200, 200
    dx = x - center_x
    dy = y - center_y
    
    # Your mathematical creativity here!
    pattern_x = x + 20 * math.sin(dx * 0.1 + t)
    pattern_y = y + 20 * math.cos(dy * 0.1 + t)
    
    return pattern_x, pattern_y

🎨 Experiment 3: Advanced Color Mathematics

Create colors based on mathematical formulas:

def mathematical_color(self, x, y, t):
    """Generate colors using mathematics"""
    # Distance from center affects hue
    distance = math.sqrt((x-200)**2 + (y-200)**2)
    hue = (distance + t * 50) % 360
    
    # Angle affects saturation
    angle = math.atan2(y-200, x-200)
    saturation = (math.sin(angle * 3) + 1) / 2
    
    # Create RGB from HSV
    rgb = colorsys.hsv_to_rgb(hue/360, saturation, 1.0)
    return rgb

🏆 Master Challenge: Interactive Art Gallery

Create an interactive art gallery that:

  1. Has multiple mathematical art pieces
  2. Allows users to switch between them with keyboard controls
  3. Saves favorite patterns as image files
  4. Includes information about the mathematics behind each pattern
