Computer generated images (known as CGI) have become very popular over the past two decades, and their importance and use will increase even further in the future because of their wide applicability in various fields. In the area of movies and films in general CGI has become an essential tool for filmmakers to bring their visions to the screen, be it by creating computer generated characters, props, sets, or just simplifying the process of image and sound editing. Film production (”Filmproduktion”) has been made faster and more efficient in the post production phase, offering an unprecedented level of freedom and quality.

The success of 3D computer animation and CGI in general started in the early 90s, when software bundles and processing power got more affordable even for smaller companies, and since then it turned into an accepted art form by itself. Over the years the technology evolved further and further, lowering the barrier between art and technology, and even allowing these two extremes to blend seamlessly.

Creation of 3D graphics

The creation of CGI and computer animation requires the use of specialized software products. Several bundles have established on the market, and it is mainly a question of personal preference which one to pick. After all the biggest factor in creating convincing digital worlds is the artist himself, whereas the software is merely the tool to transfer his creativity onto the screen.

As graphics software became more user-friendly and intuitive, the process of creating CGI started to resemble its real-world counterparts, like painting, sculpting, photography and filmmaking. The area of computer animation for example requires the same steps of “real world” filmmaking, with the addition of modeling sets, props and characters first. Bringing a mass of “digital clay” into shape to form a convincing character (or any other object or location to be shown, for that matter) is the initial step. Then cameras, lights and other entities are arranged in the virtual space, and animated if necessary. Computer animation might be called the digital successor to the classic Harryhausen-type stop-motion animation, although many other ways of animating virtual objects and characters (like physical simulation or motion-capturing techniques) have evolved over the years. The last step is called “rendering” and describes the process of collecting all information of the scene and light setup to process and output the final image through the lens of a virtual camera, either in the form of still frames, or a series of frames which create the illusion of movement.

Television, film production and commercials

Computer animation and three-dimensional visualization (”Visualisierung”) is widely used in television, commercials and film production. The “small screen” has proven to be the perfect field for experimenting with newly developed technology and concepts, and many artists working in the area of television and commercials have made their way to the movie business. With software bundles getting cheaper and more accessible, independent artists and filmmakers seized the opportunity to create their own films and short films, a development which gave the visual quality of films an enormous boost in the mid 90s. In the area of film production computer animation slowly started replacing hand-made models and puppets, and even the genre of animated films has gotten a digital counterpart.

The area of commercials has grown into other branches like industrial documentations (”Industriefilm”) and corporate video (”Imagefilm”), and besides entertainment computer animation is also used in the fields of education, interactive media (”3D Online”) and military application.

Scientific visualization

Computer animation produced to present meteorological data, medical imaging, industriefilm, architecture and technology.

Product design and engineering

Designers and engineers use special CAD (computer aided design) software for designing, developing and manufacturing consumer and industrial products. Product visualization extensively uses modern graphics technology and with the help of computers, designs can be rotated, cut and manipulated even before getting manufactured. This greatly helps engineers visualize the product that they are designing.

After spending money on a quality digital camera, it is important to take the time to maintain it properly. Your camera will last much longer if you take preventative measures to keep it in the best condition.

The most important, and delicate, component of your digital camera is the camera lens. This serves as your window to the world, and once scratched it will require professional intervention to fix. For this reason, it is imperative that you protect the lens. First of all, when you are not taking photos your lens cap should always be on to keep the lens clean. Do not touch the lens directly with your finger. The oils left behind by your skin will be difficult to remove, making the view blurry at best. If your lens should get dusty or dirty, use a cleaner and cloth made specifically for cleaning camera lenses.

The body of your camera should also be kept clean and free of debris. Keep the camera in a case or pouch when not in use. If it should get dirty, wipe it down with a soft dry cloth. If you camera has an LCD panel, it is acceptable to breath lightly on it to add slight bit of moisture before wiping it down with a soft cloth.

Digital cameras should be kept dry. Most cameras are not waterproof, and should not be in situations where they could be submerged in liquid or even splashed. If your camera should get wet, it is a good idea to turn it off, remove the battery, and remove the memory card. Leave the camera out to air dry for one to two days. At that time if the camera is not functioning properly you will need to contact a professional repair company or the manufacturer for advice.

In general, your camera will do best if stored in mild, dry conditions. Extreme temperatures can be damaging so try not to leave your camera in your car or any super sunny locations. Another good idea is to save the silica gel packets that come with many purchases to prevent moisture damage, and place them in the drawer or container where your camera is stored. If you plan to store your camera for a long period of time without use, you should first remove the battery from the camera. This precaution will prevent damage in case the battery should leak.

Finally, if you are planning to take photos in a location where you believe there will be a higher risk of damage from water or soil or other conditions purchase a disposable camera and leave your digital at home. Better safe than sorry.

Not so long ago, if you said you needed to make a phone call that meant going to the nearest land line phone. The phone could be used for nothing but placing calls and you couldn’t take it with you. It wasn’t until 1973 that the modern cell phone as we know it was born.

One of the best things about mobile phones is that you can play all sorts of games on them. Originally, they came with just the most basic games. Thanks to some wonderful inventors and technicians out there, we now have java games that have opened a whole new world in mobile gaming.

The most basic java games are strategy games. These are mainly solitary games like Mine Sweeper, Reversi or Bejeweled. There are also card games like solitaire and blackjack. They are fun and familiar to computer users and are a great way to occupy you while you wait for your appointment.

Then you have old favorite two dimensional action games like Pac Man and Galaxian. No more need to go to the arcade or pack your trusty old Atari or Family computer with these games in your phone. They can help take your mind of the long wait for your bus to arrive.

The best of the java games are in 3D. There is quite a variety to choose from. All you need to do is check what’s available for your phone model. The next step is to download your chosen adventure.

What is your game? Do you love basketball? Would you like to be out on the green shooting a hole in one but can’t because you’re stuck at the dentist? If so, then you’ll love the many java sports games available. Tiger Woods’ PGA Golf Tours game can be quite a challenge and And1 Streetball will keep you on your toes and keep your mind off the upcoming root canal.

Want to catch some bad guys? Are you a soldier at heart? Then you’ll love shoot’em up Java games like Metal Gear and Ghost Recon.

Maybe you just need to get your mind off your worries for a bit. How about playing some simulation games? You can do some Sim Fishing and catch the big one. How about taking a drive? Try out Freestyle Moto-X II or Driver Vegas and see how well you can control the wheel.

Why not go on an adventure just like in your favorite stories. Want to be a sorcerer or an elf? What kind of skills do you possess? Use them in the various role playing games (RPG) like Warhammer 40K or Bogor’s Castle. There’s no adventure like being around Ancient Ruins or a Forsaken Fortress.

You may even find a java game of your favorite movie or TV shows and be part of the team of Battle Star Galactica or Mission Impossible. There’s even a java game of Miami Vice.

Some of these games even have a multiplayer option so that you can have an adventure with your friends, no matter if they live in your neighborhood or not. Just be careful not to get over enthusiastic and fall out of your seat.

Probably the most popular mobile phone customization accessory among all mobile phone users are MP3 ringtones. Hearing actual song snippets or live recordings of the voices of your favorite friends or family members never loses its appeal. Not only are mobile phone users addicted to it but also anyone who hears these pleasant sounds as well. An MP3 ringtone is so much more attractive and compelling to hear compared to the very artificial sounds of polyphonic and midi ringtones – which sound so robotic and are more at home as sounds that come out of microwave ovens or washing machines.

MP3 ringtones come in a dizzying array of forms. There are music ringtones available in all possible genres, dialogues taken from movies, humorous dialogues or parodies, sound effects, even the recorded voices of loved ones like your children or your wife or husband. By far, the most popular MP3 ringtone type though are music ringtones. There is just something especially cool when you hear your favorite song snippet announce that you have a phone call. A song also best describes your personality – romantics will opt to have love songs, artistic types may go for rock and lovers of nostalgia may decide to have standards or 50’s music as their ringtones.

Getting MP3 ringtones for your phone is so easy now. One of the most popular sources is the internet. There are so many websites that sell MP3 ringtones of the most popular songs as well as oldies for download. With just a few clicks of the mouse you can download an MP3 ringtone to your phone.

But what if the song that you are looking for is not available anywhere? The answer is quite simple. You can make your own MP3 ringtone using your own music.

Making your own MP3 ringtone from music found on a CD you own is relatively easy. You just need to download a few free applications online to help you convert an MP3 into a ringtone.

Here is a step by step guide for Windows users:

* The first thing you should do is to download a couple of freeware applications on the net. These are Audacity and Lame (along with the RazorLame GUI). These applications are widely available and can easily be found by using a search engine. After downloading and installing the applications we can go to the next step.

* Insert the CD you want to get the MP3 from and open the free Windows Media Player. Click on the RIP button and either rip the whole CD or the particular track into an MP3.

* Open the selected MP3 in Audacity and edit the song by selecting the portion of the song that you want to become your ringtone. It is up to you to decide how long you want to make your ringtone

* Select the last two seconds of your selected portion and put a fade out effect. This is an optional step.

* Export the selected MP3 portion as a WAV file.

* Open Lame and the RazorLame GUI and tweak the desired filesize and quality that you want.
