Climate Change Quicker Than Predicted

October 16, 2009 by Paul Roth Comments Off

An increasingly large amount of peer-reviewed research, published since the IPCC 4th Assessment Report was released in 2007, shows that global warming is happening right now, and that it is quicker than predicted just 2 years ago.

The evidence for this statement is from many areas. Some of the areas showing change are shown below.

-Multiple ecosystems, in multiple locations, now show the effects of global warming. Examples include the timing of plant flowering, animal breeding, and lake thawing.

-Warmer ocean surface temperatures in Pacific & Atlantic hurricane-formation zones leading to stronger storms are significantly linked to human-induced warming.

-Ocean acidification is happening rapidly, as a result of CO2 in large amounts being dissolved in sea water. This will have massive changes on marine ecosystems and also food security for many nations.

-Calculated sea level rise this century will be greater than that calculated just 2 years earlier. It is expected to rise at least a meter, according to new scientific evidence.

-The increased melting of the Greenland ice sheet which began in the summer of 2004 has been definitely related to global warming.

-The West Antarctic Ice Shelf has undergone rapid melting over the last 10 years and has suffered 10 major ice shelf collapses over that time.

-Northern polar sea-ice is melting much quicker than previously estimated, and it is likely that the Arctic will be free of ice in summer within a few decades.

-Permafrost in the Arctic Circle is thawing much quicker than recently thought, and is releasing larger amounts of greenhouse gases than predicted.

The climate change that we are now witnessing is expected to continue for millennia, even after all anthropogenic carbon dioxide production stops. This is because of the major lags present in the climate system, and the slow removal of CO2 from the atmosphere.

Computer 3d animation The High Tech Illusion Of Life

July 21, 2009 by Jasque Brisk Comments Off

As human society has made progress, its aesthetics have also found new and ingenious means to portray itself. Today, the evolution of art has entered the domain of modern technology, as animation was created as a new art form. This has been a drastic change from the simple beginnings which can be traced back to the Lascaux cave paintings, but nevertheless, it has presented us with exciting opportunities.

Three Dimensional Animation is a process which makes it possible to create and show digital moving objects with a Three Dimensional touch on a 2D screen. 2D animation has been around for a long time, but 3 Dimensional animation has overtaken it as the results of the later are stunningly realistic. Three Dimensional Animation is not restricted to movies, but is also used in computer games, architecture, constructing models and samples, and as a web designing and communication tool.

3 Dimensional Animation consists of an elaborate process of 3D modeling, texturing, animating and rendering. 3D Modeling is the sculpting of any object or a scene in its digital 3D representation through specialized software. Texturing gives a life like shape to the 3 Dimensional models, which makes it possible for the audience to relate to an object or a person, or even a location in a 3D Animation. It is much like painting into pencil sketches and gives the model its finished look.

3D Animation may not look like the cartoons where characters like Mickey Mouse were first displayed, yet the central concept of animation remains the same as in traditional animation. These concepts have taken the form of Motion Capture and Key-framing with the development of computers. Key-framing, descendent of traditional animation technique, involves setting up of two or more key object positions in different time frames , these frames were then called key frames. After this the animator assistant was drawing all the frames in between the key frames by hand, these gradual changes in repetitive illustrations that made up the animations where called by animators in-betweens. Today the computer fills the 3D Animation by automatically generating the frames in between.

Motion Capture is a procedure of recording of motions of real objects for a near-reality imitation in an animation. The method is expensive, but can bring breathtaking reality to the cartoon production if carried out in a proper fashion. The actor who is to be imitated is wearing a motion capture suit which conveys his movements through motion sensors to the digital actor. 3D Animation, in order to hold its realistic look, needs higher frame rates than traditional animation, or even television broadcasts, which are about 14 frames per second.

Computer Animation is a challenging and exciting career. Before you start some serious professional work, it is always helpful to thoroughly research quality institutes that offer animation courses. You should focus on schools like Sheridan and Vancouver Institute of Media Arts, to really have a substantial foundation to your career. However, attending small courses will do you no good as this way you will only learn to work with different software, which is not enough to become a great 3D Animator.

Besides formal education, you should be focusing on developing and refining a number of skills to become a successful animator. You should be well versed with key animation concepts and skills like constructing animation variables, which are the building blocks of animatable characters.

You must master the basics of composition and must have a deep knowledge and understanding of how colors work. You will be continually playing with them for the rest of your lives. You must have a good sense of shade and light, which actually sum up the basics of all visual arts. Besides the technical knowledge, it is your sense of story-telling and film-making which will help create a compelling animation.

But what if you are not a professional animator? That still does not stop you from benefiting from it. A number of 3 Dimensional Animation packages exist to help you out. 3ds max, Maya, XSI, Lightwave and Hash Animation Master are very wide spread but complex software, and top choices of professionals. Although some of them are accommodating to novices, you could find yourself more at ease with simpler software like 3D GIF Designer, RealSoft 3D and Effect 3D. You should research carefully before buying one of them, as you would want all the features and tools you need from a single package as per your needs.

Website developers could utilize 3D Animation to their advantage by adding 3D Animation content on their websites. Not only will it express messages more efficiently, but it will also attract traffic to their websites. With all the ease with which you could create your very own 3D communication and presentation tools through a myriad of specialized software, not using them could literally cost you a competitive edge.
