Box modeling is a technique in 3D modeling where you take a basic primitive shape (like a box, cylinder or others) and make the basic shape “rough draft” of your final model from there you sculpt out your final model. The process uses various tools and steps that sometimes get repeated again and again until you're done. Despite the fact you’re repeating these steps you will model faster and control the amount of detail you wish to add, slowly building your model up from ground level of detail to high level.
Subdivision modeling is derived from the idea that as a work is progressed, should the artist want to make his work appear less sharp, or "blocky", each face would be divided up into smaller, more detailed faces (usually into sets of four). However, more experienced box modelers manage to create their model without subdividing the faces of the model. Basically, box modeling is broken down into the very basic concept of polygonal management.
Quadrilateral faces, commonly named "quads", are the fundamental entity in box modeling. If an artist were to start with a cube, the artist would have six quad faces to work with before extrusion. While most applications for three-dimensional art provide abilities for faces up to any size, results are often more predictable and consistent when working with quads. This is so because if one were to draw an X connecting the corner vertices of a quad, the surface normal is nearly always the same. We say nearly because, when a quad is something other than a perfect parallelogram (such as a rhombus or trapezoid), the surface normal would be different. Also, a quad subdivides into two or four triangles cleanly, making it easier to prepare the model for software that can only handle triangles.
Advantages and disadvantages
Box modeling is a modeling method that is quick and easy to learn. It is also appreciably faster than placing each point individually. However, it is difficult to add high amounts of detail to models created using this technique without practice.
