Expressive Anatomy Part 3 - the body



Last week we increased vocabulary and then translated the new words we learned into facial expressions. This week, we will be doing the same thing, but attempting to use the whole body to express an emotion. This will help us study the human figure, a study that is paramount to anime/manga creation.

Knowing how to draw the human body is actually a lot more mathmatical than one might imagine. Above is Leonardo Da Vinci's "Vitruvian Man"; a drawing that investiages human proportions in comparison to the GOLDEN RATIO.

In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant, approximately 1.61803398874989.[1] Other names frequently used for the golden ratio are the golden section (Latin: sectio aurea) and golden mean.[2][3][4] Other terms encountered include extreme and mean ratio,[5] medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut,[6] golden number, and mean of Phidias.[7][8][9] In this article the golden ratio is denoted by the Greek lowercase letter phi (\varphi \,), while its reciprocal, 1/\varphi \, or \varphi^{-1} \,, is denoted by the uppercase variant Phi (\Phi\,).

The figure on the right illustrates the geometric relationship that defines this constant. Expressed algebraically:

 \frac{a+b}{a} = \frac{a}{b} \equiv \varphi\,.

This equation has one positive solution in the set of algebraic irrational numbers:

\varphi = \frac{1+\sqrt{5}}{2} = 1.61803\,39887\ldots.\, [1]

At least since the Renaissance, many artists and architects have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing (see Applications and observations below). Mathematicians have studied the golden ratio because of its unique and interesting properties. The golden ratio is also used in the analysis of financial markets, in strategies such as Fibonacci retracement.


NOW - Leonardo has settled on certain ideas of proportion that appealed to him as a man living in fifteenth century Italy. As we will see from the school hand-out, in cartooning, you have complete control of what the human body looks like and you can create your own proportions.

LESSON ONE:

Mini lesson using "How to draw the Marvel Way" to investigate drawing the human body.

Lesson two:

Using your new found information on "FIGURE DRAWING" - draw a human body that is expressing the emotion on your flashcard.

Lesson three:

when everyone is done, students will go to the front of the class and pose in emotions for the other students to draw.



On flashcards there will be 20 emotions written on paper.
