How To Smooth The Edges Of A Polygon Model

Polygon models which have surfaces that appear curves are actually created with tiny series of lines. These lines can be smoothed in the rendering process making the lines appear smoothed, and authentic. Many created 3D models are created from these series of tiny lines, but have the appearance of curved surfaces such as furniture, or vehicle 3D models.

Sharp angles and corners are the targets of these tools to create a lifelike image. In the making of a 3D model there are three main types of smoothing that can occur in the making of a 3D model; forced smoothing, super forced smoothing and beveled smoothing.

An image can be smoothed to the user’s satisfaction – but trial and error is the best way to determine when an image has received enough tweaking and smoothing. Over smoothing occurs within many novice 3D modelers, and can be avoided with practice. Many tutorials are available on the internet for modelers to take advantage of.

Forced smoothing includes the smoothing of the vertices. To get this smooth grouping on the surface of the mesh, vertices must be split away from the parent polygon creating the image of the smoothed surface. Over smoothing can lead to edges looking “too soft” or “mushy”.
Forced super smoothing consists of a smoothing process that removes the additional polygons from the mesh, separating them from the parent polygons. Forced super smoothing of a 3D model allows the user to move the polygons a fraction to create a smoothing effect on the 3D models.

Beveled Smoothing adds extra polygons to the 3D model to create the smoothing effect on the shell of the3D model. This insertion of polygons creates extra space for light to be distributed over the 3D model and allow for shadows and shading occurring. These extra faces of the polygons create detail, creating a smoothed and lifelike 3D model.
