Common Techniques for 3D Modeling
Being associated with Design industry for more than a decade we have seen numerous trends shaping up & taking industry by storm; here in this article we‘ll be highlighting some of the trending techniques designers use for getting there 3D Modeling job done precisely as per the client’s requirements.Most extensively used by designers these days is a technique called Box modeling which as such is a polygonal modeling technique wherein artist starts with a 3D geometric primitive like sphere or cube or cylinder and then hones its form until the desired appearance is achieved. Designers following box modeling work in stages, starting with a low-resolution mesh, refining its shape and then sub-dividing the mesh to smooth out hard edges and add details.
Yet another polygonal technique many a times applied along with Box technique is Edge or Contour Modeling. Quite opposite to Box technique in Edge modeling, rather than initiating from primitive 3D shape & refining the model is fabricated section by section by placing loops of polygon along prominent contours & finally filling the gaps between them. As compared to Box modeling this may be sounding complicated but certain meshes like human face are quite difficult to complete through stand-alone box modeling technique.
Modeling work where smoothly interpreted surfaces are needed for example for automotive and industrial modeling, the most extensively used modeling technique is known as NURBS. In contrast to polygonal geometry, a NURBS mesh has no form or face or edges or vertices. Instead, NURBS models are comprised of smoothly interpreted surfaces crated by “lofting”a mesh between two or more Bezier curves or Splines.
Disruptive technologies are the breakthroughs or the technological innovation that changed the way people think about achieving a certain task and is much talked about subject in technology industry. We consider Digital sculpting techniques for 3D modeling as one of the promising disruptive technology for Design’s Industry. This technological innovation has helped a designer from pain staking constraints of topology and edge flow and has allowed them to intuitively create 3D models in a fashion very similar to sculpting physical clay. In this technique as the name suggest, meshes are created organically using a tablet device to mold and shape the model almost exactly like a sculptor would use rake brushes on a real chunk of clay. Sculpting has taken character modeling to a new level, making the process faster, more efficient and allowing artists to work with high-resolution meshes containing millions of polygons.
Though not very popular but some of the other modeling techniques designers work on today are procedural modeling – as the very name suggest, the scenes or objects are created based on user definable rules or parameters or procedures via algorithms, rather than being created manually by the hand of an artist.
