3D Moddeling

1. 3D Moddeling Dean Edwards

2. Vertices A Vertices is a point that defines co-ordinates in either 2D or 3D space, without vertices, no objects would ever exist, so therfore Vertices are the most important part of 2D and 3D objects. You need 3 Vertices to form a triangle, which can then be seen, also known as a face.

3. Edges Edges, connect each verticetogether, Edges also make thetrainglesin the polygons, to create a face of a 3D model you need at least 3 Vertices, creating 3 Edges, and one face. Finishing where you started will create a face.

4. Faces Faces are made up of 3 Vertices (or corners) and 3 Edges (or sides), Faces are simply the shaded area that we can see inside there are 3 or more Edges. Without Faces we would not be able to see 2D or 3D objects and would only see a line view, made up of the Vertices and Edges.

5. Polygons A Polygon is a 2D objects composed of 3 or more Edges and Vertices. It is simply an object that has a face, made up of 3 or more Vertices and Edges. The most common polygon is a triangle, because it is only made up of 3 Edges and Vertices. Polygons can later be put together to form 3D objects.

6. 2D Co-ordinates 2D Coordinates are comprised of only 2 points therefor only 2 axis are needed , X and Y. X always goes across, and Y upwards. 2D Coordinates can be used to create a polygon on a 2D canvas. 3 coordinates are need to create the smallest polygon, a triangle.

7. 3D co-ordinates Unlike 2D Co-ordinates, 3D co-ordinates are made up of 3 numbers as apposed to 2. 3D Axis are X, Y and Z, Z creating the depth in the world. To create a 3D Object, at least 4 3D co-ordinates are needed, if done correctly this will create a pyramid,
