HA7 Task 3 - Geometric Theory

Geometry Theory

The basic object used in mesh modeling is a vertex, a point in three dimensional space. Two vertices connected by a straight line become an edge. Three vertices, connected to each other by three edges, define a triangle, which is the simplest polygon in Euclidean space. More complex polygons can be created out of multiple triangles, or as a single object with more than 3 vertices. Four sided polygons (generally referred to as quads) and triangles are the most common shapes used in polygonal modeling. A group of polygons, connected to each other by shared vertices, is generally referred to as an element. Each of the polygons making up an element is called a face. 



Vertices
vertices are used all the time in computer graphics, they define the corners and the surfaces of the 3D objects, Verticals are points that explain the corners of the geometric shapes. In cinema 4D you can edit the vertices so that you can change the shape of the model. Vertices can be use on complex shapes to smooth it out or too add more things to the object.



Polygons
Vertex is a basic object in mesh modelling. It is were two verticals get connected by a straight line and this becomes an edge. The simplest polygon is a triangle which are three verticals connected together to make three edges. A group of polygons is normally called an element, this is a group of triangles or quads. A face are the polygons that make up the element. 

   
Lines,
Lines in cinema 4d is quite stright forward and from a line you can create a new object. With a line you can make it into a spline and put a lathe on it, to make it into a 3D object. Verticals can also be added in cinema 4d and can be made to make unusual shapes and objects.

Edges
An edge in cinema 4D is two lines connected and is the connection between them. A edge is known as a connection of two verticals. Something you can do with an edge is if you put it in an editable position you can make all kinds of objects.
