Real-Time Modeling Techniques in the 3D World.

The best way to ensure that your model has appropriate detail where it is needed and the lowest-possible polygon count is to create the model with a low polygon count to begin with, and then to add detail and subtract faces only where necessary. The Sub-Object editing tools of the Editable mesh become your best friends when you finalize a real-time model. For object creation, however, the best options fall into the following two categories:

"Conscientious" lofting.

Modifying primitives.

Conscientious Lofting Lofting Mesh objects has long been a mainstay for creating complex shapes in any 3D Application and continues to be a critical MAX tool for the real-time artist. Lofting with Deform-Fit creates beautifully detailed meshes by adding interpolative steps between vertices on both the Fit shapes and the shape(s) being lofted (Free 3D Model).

Unfortunately, this can add a tremendous number of polygons very quickly. By lofting with no added steps and by using multiple shapes on the loft path, however, you can generate extremely detailed models with predictable face counts and detail. Also, lofting objects this way creates clean cross-sections that can then be divided by BSPs, if necessary. Deform-Fit works by creating a path that derives its shape from the vertices of the two fit shapes. Wherever a vertex is present, a path step is inserted.

If the two fit shapes share the same vertices in the same alignment, a minimum number of path steps is created, therefore creating the minimum amount of geometry in the Loft object. To insure the fit shapes contain the same vertex alignment, you just clone the more complex of the two shapes. If it is properly done, a low-res car that closely approximates a more detailed model. Using the detailed model as a template, you can construct a lower-detailed version using the Deform-Fit options within the Loft object.

You could add modifications to the original Loft shape and place them on your Loft path to further enhance the detail of the vehicle, without adding more faces. The level of detail can be taken as far as necessary, however, by manipulating the vertices of multiple cross-section shapes and placing them into the existing path steps (Free 3d model).
