HOW THE TOYS IN MOVIE 'TOY STORY' MADE?

ADVT: SMARTWATCHES IN AMAZON

The Pixar company made many successful animation movies. The toy story was the beginning. The toy story series was a huge success.

The toys should have smooth curves and surfaces. From roughly drawn lines, they created smooth curves. We are going to see how they made it. The process is called subdivision surfaces.

Study the following figures.

Here a triangle is converted into a smooth curve.

SUB-DIVISION RULES

1. Insert two new vertices at 1/4 and 3/4 distance on each edge.

2. Remove the old vertices (corners)

3. Connect the new vertices.

4. Repeat the process until you get a smooth curve.

In the end, sharp corners are cut, and we get a smooth curve. A toy's face, nose, fingers, etc. can be made this way. Remember, points make up curves. Curves make up surfaces. Surfaces turn into a 3D toy. Catmull and Clark devised this algorithm.

A FEW MORE EXAMPLE

Artists simply create a jagged version of what they would like to see on screen and the sub-division blob-uses it, leaving a smooth finished product. By revolutionizing mathematics, Pixar has literally changed the face of animation.

THE EARTH, A SUPER ORGANISM

JOIN MY COURSE: "Become a programmer in a day with python" A man called 'love lock' (what a name) proposed a theory called Gaia theory, named after Greek Goddess. It says, "Earth is a self-regulating organism like a human being. The organic life in it interacts with in-organic matter and maintains atmosphere, temperature and environment". Hence the earth is still suitable for the life to thrive. Imagine, in a particular place, there are lot of flowers. Some flowers are white and some are darkly coloured. We know, white reflects light and heat while dark absorbs the same. White flowers can thrive in hot climate. But dark flowers requires cold climate. The absorption and reflection balances and the environment reaches average, warm temperature at which both the flowers can co-exist. This is the essence of "Gaia" theory. On our earth, ...

THE PARABOLA

A jet of water shooting from a hose pipe will follow a parabolic path. What is the so special about parabola. Y= x^2 Draw a graph for the above equation. It will result in a parabola. This parabola is also called unit parabola. Any equation involving square will yield a parabola. Example: Y = 2x^2 +3x+3 (also called quadratic equation) X= 2 and -2, both satisfies the equation 4 = X^2. Parabolic equations always have two solutions. Any motion taking place freely under gravity follows parabolic path. Examples: An object dropped from a moving train, A bomb dropped from flying plane, A ball kicked upwards. If a beam of light rays fall on the parabolic shaped mirror, they will be reflected and brought to focus on a point. This fact is made use of in Dish Antenna, Telescope mirrors, etc. ...

DISORDER IS THE "ORDER OF THE DAY"

Imagine a balloon full of air. The air molecules are moving randomly inside the balloon. Let us pierce the balloon with a pin. The air rushes out. Why should not the air molecules stay inside the balloon safely and ignore the little hole? That is not the way the world works. The molecules always "want to occupy as many states as possible". Hence the air goes out in the open to occupy more volume. The things always goes into disorder (entropy) and the disorder increases with time. The above statement is what we call "second law of thermodynamics". Consider a cup of coffee on the table. Suppose the heat from entire room flows to your cup of coffee, the coffee will boil and the rest of the room will freeze. Freezing means bringing things to order and arrangement. It violates the second law. Hence it will never happen. Hence heat must flow from high ...
