Double dice graphics in Python

Double dice graphics in Python

To create a graphical representation of double dice in Python, you can use libraries such as matplotlib for plotting or Pillow for image processing. Here's how you can create simple graphics of double dice using both approaches.

Using Matplotlib

matplotlib is a powerful library for creating static, animated, and interactive visualizations in Python. Below is an example of how to draw two dice using matplotlib.

Example Code:

import matplotlib.pyplot as plt import numpy as np def draw_die(ax, x, y, face_value): """ Draw a single die with a given face value at position (x, y) """ # Die face dimensions size = 1.0 face_colors = ['white', 'black'] # Create a grid for the die face ax.add_patch(plt.Rectangle((x, y), size, size, edgecolor='black', facecolor=face_colors[0])) # Define die dots positions based on face value dots = { 1: [(0.5, 0.5)], 2: [(0.25, 0.75), (0.75, 0.25)], 3: [(0.25, 0.75), (0.5, 0.5), (0.75, 0.25)], 4: [(0.25, 0.75), (0.25, 0.25), (0.75, 0.75), (0.75, 0.25)], 5: [(0.25, 0.75), (0.25, 0.25), (0.5, 0.5), (0.75, 0.75), (0.75, 0.25)], 6: [(0.25, 0.75), (0.25, 0.5), (0.25, 0.25), (0.75, 0.75), (0.75, 0.5), (0.75, 0.25)] } # Draw the dots for (dx, dy) in dots[face_value]: ax.add_patch(plt.Circle((x + dx * size, y + dy * size), 0.1 * size, color='black')) def draw_double_dice(value1, value2): """ Draw two dice showing value1 and value2 """ fig, ax = plt.subplots(figsize=(6, 3)) ax.set_xlim(0, 4) ax.set_ylim(0, 2) # Draw two dice draw_die(ax, 0.5, 0.5, value1) draw_die(ax, 2.0, 0.5, value2) ax.set_aspect('equal') ax.axis('off') plt.show() # Example usage draw_double_dice(3, 5)

Using Pillow

Pillow is a library for image processing in Python. You can create images of dice faces using Pillow and save or display them.

Example Code:

from PIL import Image, ImageDraw def draw_die(draw, x, y, face_value): """ Draw a single die with a given face value at position (x, y) """ size = 100 die_color = (255, 255, 255) dot_color = (0, 0, 0) # Draw die face draw.rectangle([x, y, x + size, y + size], fill=die_color, outline=dot_color) # Define dot positions dots = { 1: [(0.5, 0.5)], 2: [(0.25, 0.75), (0.75, 0.25)], 3: [(0.25, 0.75), (0.5, 0.5), (0.75, 0.25)], 4: [(0.25, 0.75), (0.25, 0.25), (0.75, 0.75), (0.75, 0.25)], 5: [(0.25, 0.75), (0.25, 0.25), (0.5, 0.5), (0.75, 0.75), (0.75, 0.25)], 6: [(0.25, 0.75), (0.25, 0.5), (0.25, 0.25), (0.75, 0.75), (0.75, 0.5), (0.75, 0.25)] } # Draw dots for (dx, dy) in dots[face_value]: dot_x = x + dx * size dot_y = y + dy * size draw.ellipse([dot_x - 10, dot_y - 10, dot_x + 10, dot_y + 10], fill=dot_color) def draw_double_dice(value1, value2): """ Draw two dice showing value1 and value2 """ img = Image.new('RGB', (220, 110), (255, 255, 255)) draw = ImageDraw.Draw(img) # Draw two dice draw_die(draw, 10, 10, value1) draw_die(draw, 120, 10, value2) img.show() # Example usage draw_double_dice(3, 5)

Summary

  • Matplotlib: Ideal for interactive plots and visualizations. It allows for easy customization of dice and their faces.
  • Pillow: Suitable for creating and manipulating image files directly. You can generate images of dice and save or display them as needed.

Choose the approach that best fits your needs based on the type of graphical output you require.
