Faces in 3D Modeling

In 3D modeling, nearly every shape you can make and every item you make has at least one face on it. Faces are made when the vertexes and the edges link together, leaving a face in the middle of it.

In 3D modeling, you can extrude, scale, and rotate the faces, as well as using many other tools within 3D modeling programs. Doing this to the faces will change the size and shape of the face, depending on which tool you use, to change the what the piece you are working on will look like when you finish it.

The squares in between the vertexes and edges are the faces

Polygons in 3D Modeling

Polygons in 3D modeling allows the modeler to choose a form of a shape with polygons. Polygons are flat shapes with at least 3 sides to the shape. Modeling using polygons can be used to make models such as humans, flora and animals. Apart from using polygon modeling to make these three, you can also use the technique to make hard surfaces, which can be used for industrial objects. 3Ds Max, Blender, Wings 3D and many other applications supports the use of 3D modeling.

When a 3D modeler uses polygons to make objects, the modeler is able to have a high level of control over the object he/she is creating. This makes it so that light weight models can be created that are suitable for game engines, which have limitations on the amount of polygons that can be used in a scene.

Edges in 3D Modeling

In 3D modeling, an edge is an area of a shape where 2 faces on a 3D polygon meets, (Between two vertices is where you will find the edge) When using edges in 3D modeling, you can select the edge of the shape, and shape it however you want. When you move the edges, the whole shape will change depending on where you move the edge and how you move the edge.you can also scale, rotate and extrude the edges as well to change how they look, doing this will move and shape and re size the edge depending on what is is you are doing and it will make the shape look different. You can also rotate the edges as well if you need to for what ever it is that you are making in a 3D modeling program such as Blender, 3Ds Max and other programmes.

Line Curves in 3D Modeling

Line curves in 3D modeling are used for quite a few things. First off, there are quite a few different types of line curves you can use in 3D modeling. There is the Bezier curve, Circle, Nurbs curve, Nurbs circle and Path. With each of these lines, you can curve and shape them with a colored straight line that you see on them, there are more than one on each so that you can shape them differently until you get the shape that you need. You can move and scale the line curves, as well as tilt them to an angle depending on what it is that you are making.

Vertices in 3D Modeling

A vertices (or vertex) is the cornet of a shape. A cube has 8 vertices, because it has 8 corners. To get a vertex, you need to have 3 or more edges intersecting each other. Using the X, Y and Z axes, also know as pushing and pulling verts, is the most common way to shape a polygon mesh into its final shape or form with programmes such as 3Ds max, Blender and many other different modelling programs. There are also other things you can do with vertices in 3D modeling, (if you are making a cup) if you highlight the top vertices and then delete it, you will have the top of the cup ready for smoothing and texturing.

This is a simple image showing where you would find a vertex on a shape.

Introduction into 3D Modeling

In this blog, i will be explaining about 3D modeling, the geometric theory of different styles, tools and techniques, i will be talking about mesh construction and also constraints that needs to be applied when doing 3D modelling so the file sizes are not too much for what it is you are making. This will include things such as vertices, polygons, meshes, box modeling, polygon count, rendering times and much more.
