Computer graphics

Computer graphics are graphics formed using computers and the depiction of image data by a computer especially with help from dedicated graphic hardware and software.

The communication and understanding of computers and interpretation of data has been made simpler because of computer graphics. Computer graphic development has had a major impact on many types of media and has transformed animation, movies and the video game industry.

The term computer graphics has been employed in a wide sense to describe “almost everything on computers that is not text or sound". Usually, the term computer graphics refers to a number of different things:


  • the depiction and handling of image data by a computer
  • the different technologies used to produce and control images
  • the sub-field of computer science which studies methods for digitally synthesizing and controlling visual content

Computer graphics

In computer graphics, a sprite (also known by other names; see Synonyms below) is a two-dimensional image or animation that is integrated into a larger scene. Initially including just graphical objects handled separately from the memory bitmap of a video display, this now includes various manners of graphical overlays.

Originally, sprites were a method of integrating unrelated bitmaps so that they appeared to be part of the normal bitmap on a screen, such as creating an animated character that can be moved on a screen without altering the data defining the overall screen. Such sprites can be created by either electronic circuitry or software. In circuitry, a hardware sprite is a hardware construct that employs custom DMA channels to integrate visual elements with the main screen in that it super-imposes two discrete video sources. Software can simulate this through specialized rendering methods.

As three-dimensional graphics became more prevalent, sprites came to include flat images seamlessly integrated into complicated three-dimensional scenes.

Birch

Birch is a broadleaved deciduous hardwood tree of the genus Betula ( /ˈbɛtjʊlə/ Bé-tu-la), in the family Betulaceae which also includes alders, hazels and hornbeams and is closely related to the beech/oak family, Fagaceae. The genus Betula contains from 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically rather short-lived pioneer species widespread in the Northern Hemisphere particularly in northern temperate and boreal climates.

9/11

I was reading another blog entry about 9/11. See it here

and I decided to leave this comment



Firstly I want to say that my sympathies go out to all those affected by 9/11.

But I also want to say that I grew up in Northern Ireland during the “troubles”. I was surrounded by terrorism every day of my childhood. I lived under the threat of bombs and shootings. I was surrounded by soldiers with machine guns in everyday life. Our local news was littered with the deaths of innocents and the not so innocents. Our airports have always had the level of security that you describe. As a child I had to run to escape a bomb, as a teenager I saw a man being shot outside a Belfast shopping centre. Countless others witnessed and were part of even more Horror.

Terrorism is not new.

It has grown in scale. It affects more people and has grown in complexity. It is and always has been an evil thing.

But, it will never change if we continue to hate. It is impossible to fight terrorism with fear and war. That only creates more terrorists. I think (and it is only my opinion) that the only way to combat terror is with love and understanding. We have to learn what it is that would make someone commit such an atrocity. We have to understand the reasons. We have to learn how to put such Horror behind us and move on. We have to honour those people who have been hurt or killed but without honouring the hate.

Innocence does not last for ever, neither should complacency. We are all part of this world and it is up to us to make it a peaceful place.

Northern Ireland is small in scale in comparison to the new terror. But I think it would be a sad thing if the lessons that were learned there, were not passed on now, to the rest of the world. Northern Ireland’s “troubles” are not over. We have not figured out the secret yet. But the whole world needs to start working towards it. And in my humble opinion hate will never be the answer.

Hmmmmmmmmmm

I read so many Blogs now and really wish I could write so well as some of the people I have found on the internet. I do wish I could give this a proper go and just see what happens. I love the feeling of being connected to so many people all over the world. Even if it is in a very surreal way. I too would love to be able to write witty or heartfelt things and feel as if I was a more substantial part of this community. Maybe I will give it a go and just see if I can find inspiration.
