What’s the Difference Between 2D and 3D Anyway?

Isn’t it obvious? Well, apparently not quite, when you consider how many people are still struggling with this topic!

The first concept you must grasp is that 3D means 3 dimensional and 2D means 2 dimensional. Now before you think I’m stating the obvious, let me go on to say that the 3D and 2D in animation refer to the dimension in which the animation was created. Ahhhh. The plot thickens eh?

For 2D animation, everything happens on a 2 dimensional platform. Pictures are flat, without depth and offer only one perspective. Objects and characters are usually drawn without the subtle soft shadows we see in real life and colours have few varying shades. In 3D animation, everything happens on a 3 dimensional platform. Pictures have depth and offer multiple perspectives just like in real life and have soft subtle shadows casted on the objects and characters within.

In 2D, characters look cartoonish and unrealistic. In 3D, characters can look cartoonish but realistic at the same time.

Another way to think of this is to think in terms of a painting and a sculpture. 2D is a painting, and 3D is a sculpture. 3D introduces “depth perspective,” so we not only see a rectangle (2D) but a CUBE (3D). You may also want to think of it like being the difference between a photograph of a glass of water (2D) and being able to reach out and actually pick up the glass of water (3D).

Typically, 2D involves “drawing,” or movement on, say, a flat surface (sketch pad, etc.) or in the vertical and horizontal planes. 3D involves “modeling,” i.e., creating objects in 3-dimensions using a computer software, residing in an expansive virtual environment, complete with lights, reflections, other objects, shadows, etc.

You could start training yourself by comparing a cartoon like Bugs Bunny, Aladdin, Lion King (2D) to “Toy Story 1,2 & 3, “Finding Nemo” and “Incredibles” (3D). If you have not watched any of these great cartoons, you should grab one right away or be branded a Neanderthal forever!

The Psychology of Entertainment

On the private and public forms of entertainment and the psychological mechanisms in entertainment

Entertainment has many dimensions and could be personal/private or more general and public forms of entertainment. When we play with our mates that is a personal form of entertainment and when we sit and watch a movie on the screen that is a more general form of entertainment as we are sharing the experience with many others. There are some differences in our perception of private and public forms of entertainment as personal entertainment will always be based on personal experiences, our personal worldview and will be determined by personal interactions.

The more general and public forms of entertainment are less interactive and there seems to be this basic contradiction as all personal forms of entertainment are more interactive and public forms of entertainment are more personal and private. This scenario has been changing with television programs increasing audience participation in the program however interaction patterns between entertainers and viewers in any public entertainment scenario remain within strict limits and boundaries.

Entertainment takes us to a different world and feeds our need for fantasy and an escape from real life. This is especially true for entertainment that is more public or provided by the media and entertainment provided by films, theatre, music, and all forms of creative art. Films and theatre transposes us to a world of fantasy and grabs our attention so we remain engrossed as almost a part of this alternative reality. Entertainment could also be in the form of magazine stories and gossip or even celebrity culture and the psychology of entertainment could also explain the extreme craze of celebrity culture that we have in the modern world.

Celebrities seem to open up a world of fantasies and for some people knowing every move of celebrities could bring immense satisfaction as it would almost mean participating in fantasies. Fantasies help in overcoming frustrations and serve as therapeutic as they aid in the escape from realities of life. Real emotions and real life are stressful and entertainment helps us to move beyond real life and moments of stress to participate in fantasies that are soothing as we do not have to be directly involved in these fantasies and yet as spectators we can still participate in a tacit or passive manner.

Participation in any book, film or creative art is almost like sitting on a reclining chair that has the technology to soothe your muscles while you relax. In the case of entertainment we participate almost in a passive manner and although we may be very alert and awake in the process of watching a movie, entertainment gives us the illusion of non participation as we don’t have the opportunity to get voluntarily involved in the scenario. Anything that gives us some form of pleasure could be considered as entertainment although entertainment could also give us pain as when we cry when we get emotionally involved with characters while we watch a movie.

Entertainment could trigger emotional involvement and emotional reactions such as happiness, sorrow, anxiety, fear and despite these strong emotional participation, there is little or no physical activity necessary on the part of the viewer. This active-passive process is the main attraction of entertainment as entertainment enables us to be both active (in terms of emotion) and passive (in terms of physical or voluntary mental involvement). Entertainment means like films are influential yet they influence subtly rather than aggressively and this subtle influence seems to work better on the human mind than any aggressive forms of influence. We see work as duty and entertainment as pleasure although both involve some form of emotional involvement. Work at the same time requires voluntary participation, decision making and physical involvement along with emotional involvement.

Yet why is work perceived as something heavy and entertainment as methods of relaxation? The answer is unpredictability. In case of entertainment, in most cases we may not even know what to expect from a movie or a music video. This unpredictability triggers our interest as we are unable to predict what emotional states would be evoked during this mental adventure. Entertainment is usually a form of mental and emotional adventure. In cases where we do know what a movie is about, it is the feeling of emotional familiarity that drives us to experience what we already know. Suppose a video game gave us a pleasurable feeling or evoked aggression and competitiveness in us, we go back to feel the same emotion as it was pleasurable or exciting. Stretched too far these forms of entertainment could easily become addictive.

Coming back to the distinction of work and entertainment or play, work involves responsibility and despite the emotional involvement in entertainment, apart from being a passive participant, we do not have to be responsible for anything, there is no problem solving or decision making and that is how entertainment in all its form is so pleasurable as the right brain activities of decision making and the cortical regions of the brain are not activated completely yet the pleasure sensations and emotions such as the hypothalamus and left brain activities are usually activated so we tend to associated entertainment with emotions rather than problem solving and decision making.

We humans are rational beings and yet emotions still seem to rule our lives and form the core of our existence as emotions still draw us to do things that may be irrational. Entertainment being primarily emotion provoking rather than reason provoking has a major impact on people’s lives. Appreciating any forms of entertainment could switch from the stages of interest to emotional involvement and finally addiction. The celebrity culture is a direct result of the last stages of appreciation for entertainment.

An interest in celebrities comes from emotional involvement with characters in movies and there may be substantial lack of differentiating fantasy and reality so fans of celebrities are more in love with the characters these celebrities play or the traits they project rather than the personality of celebrities. The celebrity culture seems to take people to a persistent fantasy world and individuals are seen as discussing all aspects of celebrities from their shoes to their hairstyle to the cars they possess. This sort of culture could however be explained with individual need to escape reality and identify with someone in a fantasy world and would be an important element in the study of fantasy.

The study of entertainment brings out many psychological aspects of active-passive participation in emotional or mental adventure and these could be

1. Identification – Viewers often identify with characters in movies or figures in art and this strong identification helps explain the value of entertainment. Young children have seen to imitate film stars as they begin identifying with movie characters.

2. Fantasy – Entertainment feeds on the need for fantasy in people and provides an escape route from the real world. Addiction to entertainment could be the basis of reality anxiety in people.

3. Projection – Individuals tend to project their own emotions or state of mind on to a painting or a song and could derive pleasure from this

4. Regression – Entertainment could often remind individuals of their past or a part of their own life they may have forgotten and in some cases bring out the child in them. For example when older people enjoy video games, it brings back their childhood and they may become addicted to this sort of entertainment.

5. Sublimation – Entertainment is also a form of sublimation of our impulsive desires and this especially true when we participate in entertainment as in the interpretation of art

6. Displacement – In non participative and passive forms of entertainment, individuals tend to escape from reality and displace their emotions from real people to characters in movies. For example a teenager in love with a girl whom he cannot attain may fall in love with a character of a movie who may have similarities with his dream girl.

All of the above processes are ego defense mechanisms delineated by Freud and the interplay of so many defense mechanisms in entertainment suggest that entertainment is more than simply a source of pleasure and could trigger complex psychological processes in the human mind. More research would be required in this field of psychology for a complete understanding of the advantages or disadvantages of entertainment in modern society.

How To Know If Your Piercing Is Infected

You decided on a body piercing, found a reputable piercer, and survived your appointment. Now your piercing is doing something unexpected, and you’re worried that it might be infected. Are these the normal signs of healing, or are you and your piercing headed for trouble? Read on to find out how to tell if your piercing is infected.

Any time your body is injured – including piercing – you might see the five signs of inflammation: redness, heat, swelling, pain, and loss of function. These are normal and indicate that your immune system is at work, but they can also be signs of infection. The difference is a matter of degree and timing.

Symptoms

Your piercer should tell you what to expect during healing. If you know what is normal, you will be able to detect trouble early. Let’s look at the possible symptoms of infection:

Redness – It is normal for a new piercing to be slightly reddened because blood flow to the area is naturally increased. Sure signs of trouble include redness that won’t go away, an expanding area of redness, or red streaks that track away from the piercing.

Heat – Heat also occurs because of increased blood flow and indicates a problem if it increases over time, is hot and not just warm, or just will not go away.

Swelling – Swelling is caused by a build up of fluid. Oral piercings are especially prone to it – a tongue piercing can take a week to ten days to settle down. Swelling is problematic if it does not go down as quickly as expected or gets worse. Your jewelry must be long enough to accommodate swelling. Otherwise, it is very hard to clean, and there is a risk that the jewelry could pull through the piercing and be lost under the skin.

Pain – It is normal for a piercing to be tender for a few days, especially if it is subject to movement (e.g. tongue, lip), or aggravated by clothing or bumping. Pain that worsens with time or is extreme indicates a problem.

Loss of function – An eyebrow might not have a lot of work to do, but a tongue will be slowed down by a piercing, and an infection will make this worse. A pierced body part that will not move or is too painful to move is not normal – you may have an infection.

Two more symptoms

Fever/chills/nausea

- Fever, sometimes accompanied by chills and nausea, is a definite sign of trouble. You either have a localized infection at the piercing site or a more serious (potentially fatal) systemic infection. Consult a doctor if you have a high and/or persistent fever, chills, or nausea. These are not normal reactions to piercing and you may need antibiotics.

Pus/discharge – Not every discharge indicates infection. During the early stages of healing, a healthy piercing will discharge lymph, which is just blood plasma without the larger proteins. It is a clear or slightly yellowish fluid that dries to a crust and is easily removed with warm water.

Pus, on the other hand, is definitely a sign of infection. It is largely made up of dead white blood cells and bacteria. It may be whitish, yellow, green, or gray, and may have bloody streaks and an odor. Yellow, green, or foul-smelling pus indicate a serious infection. Seek medical attention.

What to do

If you think you have an infection, contact your body piercer immediately. Piercers are often more knowledgeable than doctors, who can be prejudiced against or unfamiliar with piercings. However, if you think you are in trouble or your condition worsens significantly, you must seek medical attention. If you lose a piercing, you can get it redone – it is not worth risking your life or serious tissue damage.

Mild infections can likely be treated at home. One time-tested remedy is the salt-water soak. Dissolve 1 teaspoon (5 ml) of sea salt in 1 cup (250 ml) of warm (not so hot that you scald yourself) water in a clean cup, ideally a disposable plastic one for each treatment. Soak the piercing or make a compress with a clean washcloth saturated with the salt water. Do this two or three times per day, fifteen minutes per session.

Avoid antibiotic creams or ointments as they trap dirt and debris and do not allow the piercing to breathe. Do not remove the jewelry from an infected piercing. This could allow the piercing to seal, trapping pus and causing an abscess. Pay special attention to infections in facial or oral piercings – their proximity to the brain makes them especially dangerous.

Prevention

The best strategy is prevention; follow the aftercare instructions from your piercer. He or she will recommend a mild cleanser and a cleaning schedule. Never touch a piercing with unclean hands. Never use alcohol, peroxide, iodine-based products or harsh antibacterial soaps. They are much too strong and will dry skin, kill cells, and impede the healing process.
