Normal to surfaces in 3D space Calculating a surface normal. For a convex polygon (such as a triangle) a surface normal can be calculated as the vector cross product of two (non-parallel) edges of the polygon.. For a plane given by the equation the vector () is a normal.. For a plane given by the equation () i.e. a is a point on the plane where s and t range over all real numbers v and w are given linearly independent vectors defining the plane and r 0 is the vector representing the position of an arbitrary (but fixed) point on the plane. The vectors v and w can be visualized as vectors starting at r 0 and pointing in different directions along the plane. Note that v and w can be Normal Vector. The normal vector often simply called the normal to a surface is a vector which is perpendicular to the surface at a given point. When normals are considered on closed surfaces the inward-pointing normal (pointing towards the interior of the surface) and outward-pointing normal are usually distinguished.

In this section we want to look at an application of derivatives for vector functions.

And is the distance of the plane from the origin (Gellert et al. 1989 pp. 540-541). Here the sign of determines the side of the plane on which the origin is located. If it is in the half-space determined by the direction of and if it is in the other half-space..
