The Essentials of Options – Breaking Down the Basics

Understanding 3D Modeling 3D modeling is an emerging trend in modeling that is used to create 3 dimensional images and renders. If you have seen a sculpture in your life, then you understand a thing or two about 3D modeling. This type of modeling is done using a computer software and a set of tools that work together to achieve this purpose. With the software, an artist can model or sculpt an object or image of his imagination into a 3D computer image. The computer achieves 3D modeling since every computer representation is composed of multiple polygons, each with three or more vertices. When two or more of these polygons are put together, they form a virtual object referred to as a 3D model. A 3D artist uses this available software to create outlines that will define the shape of a profile or character that he or she visualizes. To come up with the models, there are a couple of techniques that are put into use. One of the most common techniques that have been in use for a long time is primitive modeling. The only problem with this method is that it is so basic that there are drawbacks available. Primitive modeling makes use of basic shapes such as circles, spheres, and rectangles, among other shapes to suit the character being developed. This method uses primitive shapes hence it is only useful for creating definite shapes and not complex ones.

Another popular form of 3D modeling is NURBS, which is an acronym for Non Uniform Rational Bspline. In this model, a mathematical curve, represented by a set of equations, is implemented to create the desired shapes in a model. By looking at this model, all you can see is a simple set of curves that can be manipulated in any way you like. These curves are usually referred to as NURBS and can be dragged around the screen to alter their shapes.

In Surface modeling, another popular form of 3D modeling, an artist is required to develop spline cage profile for a 3D character. The splines in this case will intersect with each other allowing the creation of simple and complex shapes which form a closed profile of the character unlike in NURBS. This method has turned out to be very popular mostly because it brings together the best qualities of 2D and 3D modeling, giving artists more flexibility. Other methods include polygonal modeling which is used in both organic and inorganic modeling and the Sub Division modeling which is a hybrid between Polygonal modeling and the NURBS.
