Weighted Normals Guide

In the end, weighted normals teach us a profound lesson about computer graphics: And a well-weighted lie is indistinguishable from the truth.

So the next time you see a low-poly rock that catches the light just right—with no faceted harshness, but also no melted edges—thank the weighted normal. It is the silent mathematician, the invisible sculptor, making your sharp, economical world feel soft and real. weighted normals

To fake smoothness, we use vertex normals —averaging the normals of all the polygons that meet at a single corner. This is the classic "smooth shade" button. It works wonderfully for a sphere. But for a cylinder? You get a strange, pinched artifact at the top and bottom. For a game character’s hard-edged armor? The edges look like melted plastic. In the end, weighted normals teach us a
