These works may not make the mathematicians happy, but the numbers are pretty darn close. While this is only speculation, it does seem to be a pedantic and academic argument. This is true from ancient pyramids and famous buildings from ancient Greece to the Mona Lisa and other artworks by the masters. When the spirals of a nautilus shell are measured, their ratio to one another is not exactly 1.618.įamous pieces of artwork and architecture fail to stand up to careful study as well. One of the most common arguments against the importance of Phi is that, while Phi can be applied to many things in nature, careful analysis shows that it is seldom mathematically perfect. The larger the numbers, the more accurate the results become. The first numbers of the sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, etc.įurthermore, when two successive numbers of the Fibonacci sequence are divided, their ratio is very nearly Phi. This mathematical pattern shows numbers that are added together to make the next number. The Ratio is also closely related to the Fibonacci sequence. It has been studied and refined for two and a half millennia. The Ratio was first described by the ancient Greek mathematicians Phidias, Plato, and Euclid, as early as c. In math, the number is referred to by the Greek letter φ or Phi. It’s approximate because it is an irrational number that continues with an infinite number of decimal places. To benefit the algebraically disinclined, let’s keep it simple. But designers, artists, and photographers aren’t usually high-level mathematicians. There is a lot of math behind how the Golden Ratio is calculated. If you’d like some real-world tips on how to use it to make your work better, look no further. Precisely what is Golden Ratio composition, and can it really be applied to design and photography? As artists, should we use the Ratio, or should we ignore it? The good news is that it’s easy to apply and can indeed make your works more captivating and beautiful. And there are plenty of websites that can tell you more than you ever wanted to know. Perhaps you saw the movie The DaVinci Code and learned about it. Maybe you were introduced to it in school, in mathematics, art, or design class. We then draw the new circle and repeat.Chances are, you’ve heard of the Golden Ratio. We then calculate the xy coordinate of the new circle using the calcCentre function, which takes the parent circles' xy coords, the new circle's radius, the number of degrees around the circle we have travelled, and returns the new circles centre. We then calculate the speed multiplier for each circle by multiplying the index of the circle multiplied by the Golden Ratio divided by the total number of circles we have. We must draw the first circle seperately from the others. This contains the centre of the parent, initially being the largest circle at centre (width, height). We initlise a tuple of numbers, the first number being the x coordinate and the second being the y coordinate. In the draw function we get the 2d context of the canvas element and clear the area, then set the dimensions of the canvas. On initialisation we start a timer counting up, called time, incremented by the speed parameter every millisecond. The draw function is called at the speed of the users display refresh rate, so for most people 60 times per second.
