Overview of this book

This book is for the scientists, engineers, programmers, or analysts looking for a high-quality, open source mathematical library. Knowledge of Python is assumed. Also, some affinity, or at least interest, in mathematics and statistics is required. However, I have provided brief explanations and pointers to learning resources.

Time for Action – drawing the Sierpinski gasket

For the purpose of demonstration, we will draw a Sierpinski gasket, also known as Sierpinski triangle or Sierpinski Sieve with OpenGL. This is a fractal pattern in the shape of a triangle created by the mathematician Waclaw Sierpinski. The triangle is obtained via a recursive and, in principle infinite procedure.

  1. First, start out by initializing some of the OpenGL related primitives. This includes setting the display mode and background color. A line-by-line explanation is given at the end of this section:
    def display_openGL(w, h):
      pygame.display.set_mode((w,h), pygame.OPENGL|pygame.DOUBLEBUF)
    
      glClearColor(0.0, 0.0, 0.0, 1.0)
      glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
     
      gluOrtho2D(0, w, 0, h)
  2. The algorithm requires us to display points, the more the better. First, we set the drawing color to red. Second, we define the vertices (I call them points myself) of a triangle. Then, we define random indices, which are to be used...
