Polygon edges usually appear sharp or creased. To get around this we can use smooth shading. This tutorial explores smooth shading and shows how vertex normals affect the gradient of a polygons face. We also look at how to quickly smooth shade objects with a wide variety of angles by setting angle tolerances.

Knowledge of these concepts is required: Polygons , Multisided Polygons

Creased Edge: An edge that doesn't have smooth shading. Can also be called
- Hard Edge
- Faceted Edge
- Flat Shaded

Vertex Normal: A normal (or direction in space) that comes out of a vertex. Depending on its angle it can change the gradient over a polygon, this direction is relative to the light that comes from that angle.
