Differently from most 3D modeling tutorials available, ‘s guide – republished here courtesy of its author – gives detailed information specific for achieving high-quality surfaces and reflections, suitable for automotive and product design visualization. It also makes an interesting comparison, including technical remarks, between NURBS and polygonal/subdivided geometry, which is crucial to fully understand the potentials and the limits of each technique. This is much more than a quick time-lapse video nor a step-by-step guide – it’s an in-depth lecture targeted to intermediate and advanced modelers. We suggest you to bookmark the page, study it and refer back to it when needed. Thanks again to Ali Ismail for sharing his knowledge and for letting us republish his article here. Sections • • • • • • Introduction This tutorial examines the creation of polygonal meshes with high quality curvature to produce better reflections. Artists who have experience in modeling complex polygon hard surfaces such as cars but are looking to have a better grasp on the subject will benefit more of this tutorial.

Hopefully it will also give you an understanding of the challenges involved in creating a car model and why many prefer to use NURBS to accomplish this task. By using the example of a car body, you can apply the same principles to any reflective object whether it is a boat, a futuristic concept train or a sophisticated water faucet. While this is a car modeling tutorial, it will not go into any details of the basic process of creating the mesh, specific tools or matching the reference proportions which I feel are better suited for a general modeling or hard surface modeling tutorial, you should note that the level of quality this tutorial deals with relates to rendering an object with continuous reflection streaks across it.

If all what you are after is an object reflecting an HDR sky environment and you don’t mind some reflection distortions, that the untrained eye won’t catch, then this is not for you. One reason for creating this tutorial was another tutorial that I have created many years ago when I was starting out my way in 3D graphics ( (PDF 7.0MB)).

I felt that a follow up is necessary to go into the depths of understanding the intricacies of automotive modeling and laying out the basic principles which distinguishes it from any other type of 3D modeling. Class A Surfacing Perhaps, the biggest defining characteristic of a car body is the fact that it is reflective! Highly reflective surfaces clearly expose your model curvature unlike matte objects. Imagine a dent or bump on a mirror versus on a dusty wooden cabinet. Note: for all intents and purposes of this tutorial you could define a class A surface as a surface which reflects really nicely.

If you go into car or industrial modeling for actual manufacturing, where you will be using a NURBS modeling software similar to Autodesk Alias or Rhinoceros 3D, you are bound to run into terms like tolerance and continuity. All the industrial technical details put aside what we are interested in for creating a car for rendering, is continuity, that refers to how continuous a reflection is across a surface.

To learn more about NURBS, I have a basic which you can check or you can start exploring on your own using the term “class A surfacing” in any search engine.
