To learn more about NURBS, I have a basic introduction into NURBS article which you can check or you can start exploring on your own using the term "class A surfacing" in any search engine. Rate of curvature change (G3): it’s even more blended but the difference is very small and hardly noticeable. Tangential continuity (G1): there are no sharp edges in-between the surfaces.Ĭurvature continuity (G2): the surfaces are blended together with the highlights appearing as if its on a single surface. Position continuity (G0): the surfaces are aligned and have no gaps in-between.
This tutorial is mostly about theory, to see a video recording of how I modeled a car, you can view this 3D Car Modeling Video Timelapse. 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. 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 ( Making of Mercedes S600 (PDF 7.0MB)). 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. 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. 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. 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. 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. This tutorial examines the creation of polygonal meshes with high quality curvature to produce better reflections.
