Vertices, Edges and Faces By Jordan Diamond

1. Vertices, Edges and FacesBy Jordan Diamond

2. Vertices • In geometry, a vertices is a special kind of point which describes the corners or intersections of geometric shapes. Vertices are commonly used in computer graphics to define the corners of surfaces typically triangles in 3D models, where each such point is given as a vector. • The vertex of an angle is the point where two lines begin or meet, where two lines cross, segments and lines that result in two straight sides meeting at one place.

3. Edges • An edge is a line between to vertices. The more edges you have the more vertices then the more faces which creates a more complex shape.

4. Faces • the face on a shape are the main things that help you see the object when its complete. • The faces are used to show detail in the shape which you can add texture to.

5. Polygons • All 3D models are made up of either triangle or polygons. The reason Polygons and triangles are used is because these shapes fit together to make the 3D shape.

6. Meshes • A mesh is a group of faces, edges and vertices. These make up the shape when 3D modelling. • The meshes help you manipulate the 3D objects to help you create complex shapes.

7. 2D co-ordinates • 2D co-ordinates are used to make up a 2d shape. The axis used to plot 2d coordinates are x and y, 2d co-ordinates are used to create the faces of the 3d faces.

8. 3D co-ordinates • 3D co-ordinates are used to plot 3D shapes. The axis used to plot the 3D co-ordinates are x, y and z
