Controlling edge reflectance on diffuse surfaces

This materials and rendering tutorial shows how to impart subtle surface shading for diffuse materials. Specifically, it shows how to use the fresnel interpolator to adjust the reflectance at glancing angles to help give a greater sense of dimension to diffuse shaded objects.

Creating a chemical shape, approach 2

This modeling tutorial shows how to prepare Adobe Illustrator artwork for geometry creation in Design 3D. It shows how to prepare the artwork in order to create a subdivision surface object and walks through the process of properly generating a polygon structure from this Illustrator artwork that properly subdivides.
