3D Modeling

3D Modeling

"3D Modeling is the primary step to make anything in 3D. Or we can say, 3D Modeling is a way to achieve desirable shapes or objects in CG( 3D Computer graphics) world where we use Simple primitive 3D objects like box, sphere, etc and modify it to a complex or desired 3-Dimensional Object such as a human body or house or anything you desire."

3d Primitives

And if look scientifically, In 3D computer graphics, 3Ddimensional modelling is the process of developing a mathematical representation of any surface of an object in three dimensions via specialized software. The product is called a 3D model. Someone who works with 3D models may be referred to as a 3D artist.

Here, if you want to understand who it works, then First you have to understand the basic method of modelling. Which is generally known as polygon modelling in which the mathematical equations in use to generate a shape in an empty 3D world in the specific 3D modelling software.

Where any 3d model is made of so many polygons (shown below)which are represented by a  mathematical equation.in which a single polygon or plane consist of 4 vertices and 4 edges to make a complete polygon or plane in mathematical language.

Single Polygon(plane)

The vertices and the edges are components of a single polygon. Where a vertex is a variable or container which hold the values of position(or transformation) in 3d space in the form of three coordinate (x,y,z) which mean to define the location or the distance from the origin of every coordinate on each axis respectively.

Vertex

And edges are the segments connecting two vertices as shown below. 

We also use edges as curves to form 2D shapes in 3D space or make a 3D object using 2D shapes(curves).
