Sometimes, it’s a lot smoother than we’d like….

Even when your vertices are chunky, the lighting will flow. Since normals are really important in lighting– which is really, really important in rendering– this smooths out the lighting. It uses something called interpolation to make the normals change smoothly along the face. Then it sort of averages the normals of the three vertices and uses that value for that pixel. When MMD draws pixels, it looks at the three vertices that make up the pixel’s face and figures out where the pixel lies in relation to those vertices. So PMXE takes the normals of all of the faces using a vertex, averages them, and assigns that to the vertex. Once you get to MMD, there isn’t any such thing as a face. And normals are normalized too! But they’re two different things, and a lot of things are normalized that aren’t normals. Normalization means when you take a line and lengthen or shorten it until it’s length is exactly one unit. The word is confusing, because you may have heard of normalization, which means something different. For instance, if your desk was a face, the normal would extend straight up– or straight down. Orthogonal is a fancy way of saying that it extends at right angles to the face. What are normals? What are normal maps? How can I use normal maps in MMD? How can I fix my normals? How do I make hard edges in MMD? How do I make normal maps? How can I modify normal maps? What are n ormals?Ī normal is the line that extends out orthog onally from a face.
