What is 3D?

Understanding XYZ Coordinates is the basic thing, when you are trying get in 3D world. Actually many people wish to be Master of 3D graphics and animation but they don’t even know what the place of point in a space is? With XYZ Coordinates we specify the place of a point in realistic 3D space. For example, if you are asked to draw a point in specific place of our own realistic 3D word, you will be told the location according to some origin. Such as right or left or top or bottom or front or back of something and then you will place the point there. XYZ Coordinates are the same thing. There is always an origin and you specify the distance from the origin on X or Y or Z axis and this way you draw accurate points and objects, that are actually the collection of points.

Understanding 3 Dimensions is one and only way to get in the world of 3D. Let’s try to understand what the dimensions are? When we draw something on paper like sheet or surface, we use 2 dimensions. A photograph is two dimensional thing, a shadow is a two dimensional entity as well. A 2 dimensional object is always drawn on 2 dimensional surfaces like paper, and has two axes for drawing, X, Y, one for length measurement and one for width measurement. But a 3 dimensional object has depth in addition, And cannot be drawn on 2 dimensional surfaces like paper, because a 3 dimensional object is a thing of realistic world like cup, glass, room, fan, computer, ball, book, human, pen, pillar etc. when we model a 3 dimensional object within Maya. We model it in an imaginary workspace, which gives us the illusion of realistic 3D world, and we have length, width, depth at a time. We model 3 dimensional objects on 3 axes X, Y and Z.


3D Software and Realistic World are same indeed, because according to Modern physics the realistic world is nothing more than an illusion. Most of the Western Philosophers and Scientists including Einstein the Great believe that our realistic world is nothing but just an illusion. We believe that we exist however it’s not totally true, because whatsoever we observe is just perception or conception of our five senses. Even the Father of Modern Western Descartes says, “I think so I am” otherwise nothing is to make my belief that I exist in this world. Anyhow we are not studying philosophy here, we are just trying to understand the difference between realistic world and any of 3D Software such as Maya, 3D Studio max, AutoCAD or somewhat else. When we work within Maya, actually we use a 2 Dimension Screen of our LCD or Monitor as drawing canvas. So the difference between realistic world and 3D software is clear that we just model or animate 2 dimensional entities on an imaginary 3 dimensional canvas. It’s just like drawing an apple on a paper with shades that make apple’s round rather we model things in our realistic world on a realistic canvas which is our space, our surroundings, our environment.
