A subdivision surface algorithm is recursive in nature. The process starts with a base level polygonal mesh. A refinement scheme is then applied to this mesh. This process takes that mesh and subdivides it, creating new vertices and new faces. This is a modeling technique for making high-resolution models, by manipulating a lower-resolution "cage" model and using software to subdivide for a smoother surface. Subdividing increases the number of vertices on the model, making curves more rounded. Usually each subdivision level increases the vertex count 4x the original count.
Subdivision Surfaces
Subdivision surfaces are a common modeling primitive that has gained popularity in animation and visual effects over the past decades. As the name suggests, subdivision surfaces are fundamentally surfaces. More specifically, subdivision surfaces are piecewise parametric surfaces defined over meshes of arbitrary topology -- both concepts that. Subdivision Surface Modeling Technology Home Book Authors: Wenhe Liao, Hao Liu, Tao Li Systematically introduces various useful modeling techniques for different subdivision surfaces Provides an overview of fundamental subdivision schemes and modeling techniques including work on subdivision surfaces after 2010 Subdivision modeling Many SOLIDWORKS customers are already enjoying the benefits of surfacing with the Sub-D modeling approach of 3D Sculptor on the 3D EXPERIENCE platform®. Surface modeling with Sub-D is superfast when creating contoured, ergonomic, and organic shapes. When deforming a surface made of NURBS patches, cracks arise at the seams "Subdivision defines a smooth curve or surface as the limit of a sequence of successive refinements" Generalization of spline curves / surfaces Arbitrary control meshes Successive refinement (subdivision) Converges to smooth limit surface

1 Using subsurf will subdivide the existing geometry allowing you to create smother curved surfaces. If you are not dealing with curves (what you call "hard surfaces") subsurfing will only result in extra processing time and will increase memory usage. The Subdivision Surface modifier (often shorten to "Subdiv") is used to split the faces of a mesh into smaller faces, giving it a smooth appearance. It enables you to create complex smooth surfaces while modeling simple, low-vertex meshes. It avoids the need to save and maintain huge amounts of data, and gives a smooth "organic" look to the object. Subdivision surface modeling is a popular technology in the field of computer aided design (CAD) and computer graphics (CG) thanks to its ability to model meshes of any topology. The book also discusses some typical Subdivision Surface Modeling Technologies, such as interpolation, fitting, fairing, intersection, as well as trimming and. Once you have mastered this powerful workflow you will be able to use it as a cornerstone for all of your future 3d modeling projects. Learn how to harness the power of Blender's subdivision surface modifier in conjunction with timeless procedural modeling skills to build realistic looking 3d models.

Subdivision surface modeling overview If you have never used subdivision surfaces before, the following workflow description will help you get started: 1 Create a polygon mesh that roughly captures the basic shape of the model you want to build. Ensure you initially construct it with a minimum About > Basic subdivision surface modeling workflow Subdivision Surface Modeling 9 You can switch to Polygon Proxy mode at any stage of modeling. However, if you've used deformers or created other construction history while in Standard mode, you cannot switch to Polygon Proxy mode until you delete construction history.
