The Three Methods of Modeling

There are three types of modeling that are used to create a 3D model, these are; spline modeling, box modeling and poly modeling.

The first type of 3D modeling discovered is spline modeling. Spline modeling has also been referred to as patch modeling and allows a curve to be created with the use of two control points. These points are created in multiples to create the skeletal system of the model. This form of modeling is best for objects that are not going to be animated, as they require a lot of modifications to be suitable for the animation process. Cars, furniture and real estate models are examples of which types of models work best within the Spline modeling process. These types of models require an extensive amount of curved shapes and therefore work best with Spline modeling.

The modeling form that lies the most similar to sculpting is the technique called box modeling. It begins with a cube shaped, and details the object by removing layers or slices. Again, box models can be difficult to animate and take extended periods of time to create, and perfect. Box modeling is used for objects with hard lines such as tall, traditional buildings.

Poly modeling is also referred to as edge extrusion. It is one of the most precise techniques as it will begin with a 3D image consisting of points, which are built upon. These sets of four points are referred to as quads, and the second is attached to the first, and the third is attached to the second, and so on. The model is created from the bottom up, and can take extended periods of time but requires less adjusting than traditional modeling methods. Shell models, which contain the surface shape without an interior, can be easily created with poly modeling. The most advanced technique; poly modeling has been popularized with new technology and software.
