Anatomy of Polygonal 3D Model
In this article we would like to share our understanding on Anatomy of 3D Modeling specifically for polygonal techniques as the polygonal models or meshes are the most common form of 3D models one can find in Animation, Film or Movies, Games and other 3D modeling art works.
Faces: The surface of any 3D model under polygonal modeling technique comprises of hundreds or thousands of geometric faces i.e. one of the prime distinctive aspect of a polygonal model is that polygonal meshes are faceted. In decent modeling polygons are either quads (four sided) as in case of character or organic modeling or trios (three sided) more common in game modeling. One of the quality of experienced designer is maintaining balance between efficiency and organization i.e. efficient in keeping polygon counts as low as possible for the intended shape. Also poly-count refers to the number of polygons in a mesh whereas resolution refers to polygon density. The stunning 3D models have high resolution with higher details like character’s hands or face and low resolution in low detail regions of the mesh.
Vertices & Edges: An edge could be understood as the cross section area or point where two polygonal surfaces meet, on the other hand the point of intersection between three of more edges is called vertex or vertices in plural. Manipulation or operating vertices on the axes (x, y or z) which is also referred to a pushing & pulling vertex is the most common technique for giving polygonal mesh a final shape in traditional modeling packages like 3Ds Max, Maya etc. When it comes to sculpting applications like ZBrush or Mudbox techniques differ a lot.
3D Models under polygonal technique are comprised of faces, edges and vertices. As the matter of fact creation of any complex 3D model would start from a simple geographic 3D shape like cube, sphere or cylinder; these basic 3D shapes are called primitives.
Textures & Shade: Though textures and shade got nothing to do with shape and form of a 3D Model it got everything to do with 3D Model’s visual appearance. Without stunning texture and shade any 3D model won’t look as attractive as it looks with these components. Shades is a set of instructions applied to a 3D model that lets the computer know how it should be displayed on the other hand Textures are two-dimensional image files that can be mapped onto the model’s 3D surface through the process known as texture mapping.
