Understanding Vector and Raster Graphics

Choosing the right design, the right designer and the right graphics is essential. Selecting the right business, the right platform and the right time is crucial.

If you have an artistic hand but don’t know how to write, or you have beautiful voice and you don’t know how to sing, you may have a gift, but a paralyzed one.

You have a website and don’t know what its composition is; you have graphics and don’t know how they are designed; just the lack of this information you may lose your business.

Bit vector, using Perl vec

A bit vector is just an array of bits; subsets of bits within the bytes have some meaning. That allows more compact storage for certain types of data. For example, if you only needed boolean on-off values, you can store eight values in one byte.

Vector Drawing Programs

One of the best tools in creating and modifying a vector-based image is the Adobe Illustrator. Artworks done through the Illustrator can be used for print, multimedia and online graphics.

I just saw the Japanese Animation movie Spirited Away and couldn’t help admiring the combination of cool moving graphics, computer generated backgrounds, and integration of sound. This inspired me to revisit the world of 3-D computer graphics. One of the coolest techniques in generating 3-D objects is known as ray tracing. This technique utilizes how the behavior of a particle of light (a photon) with a solid or refractive object. We are only interested in the rays that reflect into the camera or view area near the eye. This “view” area forms the image from the different colors and intensities bouncing back from the solid object.

Vector vs Bitmap Graphics

There are 2 types of graphics and it is very important to understand the difference between them.

Introduction To Scalable Vector Graphics

SVG is built on top of XML in order to describe 2D vector capable graphics. XML stands for “Extensible Markup Language”. A full description of XML is best suited for a future article since it can be quite technical. To simplify XML, it is similar to HTML but provides greater customization of the tags. HTML is a set of pre-defined tags that are used to describe a web page. XML however, does not pre-define the tags.
