3D MODEL OUTSOURCING



3D modeling is the process of creating a 3D representation of any surface or object by influencing polygons, edges, and vertices in simulated 3D space. 3D modeling can be accomplished by hand with specialised 3D production software that lets an artist to make and deform polygonal surfaces or by scanning real-world objects into a set of data points that can be used to signify the object digitally.

3D Modeling is used in a extensive range of fields including flim,engineering, entertainment design, visual effects, game development, and commercial advertising. The most famous and common  example would be the modern rebirth of 3D technology in major motion pictures where this technology is used which started with the success of the film Avatar the 2009 blockbuster from director James Cameron. The film helped to transform the 3D industry and used many of the concepts of 3D modeling. 3D modeling is closely connected to the concepts of digital sculpting and polygonal mesh.

Types of 3D Models


There are two main types of 3D models that are used in the film & games industry and the most superficial differences being in the way they’re created and manipulated
NURBS Surface:
NURBS (nonuniform rational B-splines) are mathematical representations of 2- or 3-dimensional objects which can be standard shapes such as a cone or free-form shapes such as a car. NURBS are used in computer graphics and the CAD/CAM industry and have come to be considered as a standard way to create and signify complex objects. In addition to curves and surfaces NURBS can also represent hyper surfaces.
Polygonal Model: Polygonal models as they’re often called are the most common form of 3D model found in the animation, film, and games industry.

The Components of a Polygonal Model are
  • Faces: The defining characteristic of a polygonal model is that polygonal meshes are faceted; meaning the surface of the 3D model is comprised of hundreds or thousands of geometric faces.
