What Is Digital Imaging In 3D Animation Urdu Course Pakistan Part #8

 





3D Animation is interconnected with today's computers, that is why, you need to have a good understanding of digital images and videos.


Digital photos are made in different ways, such as with the help of digital cameras like DSLR, Painting software or scanners can also be used to create a digital pictures.


To understand a digital picture you have to understand pixels, For example, pixels are used to display anything on every computer screens.


To put it mildly, Pixel is the smallest point on the screen of a computer, which can be represented by a box or rectangle.


This means that the more pixels present in your computer screen, the better the quality of your picture or video will be.


If we talk about a screen with a full HD 1080p resolution, then there are 2,073,600 pixels present there.


To display pictures, nowadays computers may use 2 types of graphics. In which the first is called raster graphics and the second is called vector graphics.


Raster graphics are plotted at points or pixels, and they also depend on resolution, For example, if you look at a 720p image that may have the same resolution, it will look crisp, but zooming in on, it gets pixelated.


Whereas vector graphics on the other hand are not dependant on resolution and are made up of geometry lines, Therefore, the vector image will not be deformed on zooming.


The pixilation that occurs in raster graphics, it is removed through anti-aliasing in 3D animation and video games.


In raster file formats, you get file formats like JPG or JPEG, TIFF, TGA, GIF, PNG, PSD, PDF and EXR file formats.


Whereas in vector file formats you EPS, AI for Adobe illustrator, FLA for Adobe Flash File, and SWF for ShockWave Flash file format.


Before showing any image on the computer screen, it is also necessary to resort to colour calibration. Because you will see every picture differently on other monitors from the colour point of view.


After which you get different colour modes for photos, such as RGB colour mode, CMYK Colour Mode, HSV Colour Mode and YUV Colour Mode.
