Unit normal vector definition
Normal Vector of a Curve. A unit normal vector of a curve, by its definition, is perpendicular to the curve at given point. This means a normal vector of a curve at a given point is perpendicular to the tangent vector at the same point.How can the answer be improved? unit normal vector definition
Dec 17, 2010 ah! as you can see, my definition also works (and is much quicker) the only difference is that my method comes up with two unit normal vectors (oppsotie each other), the one you need is is the unique vector that points into the curve , ie the one towards the centre of curvature (the concave side) for a 3D curve, you do need the book's method, to decide which one is the principal 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 inwardpointing normal (pointing towards the interior of the surface) and outwardpointing normal are usually distinguished.
Because the binormal vector is defined to be the cross product of the unit tangent and unit normal vector we then know that the binormal vector is orthogonal to both the tangent vector and the normal vector.
A unit vector is a vector that points in the direction of vector v but has a magnitude of 1 unit. Diagram 1 shows a vector and its unit vector. Diagram 1 shows a vector and its unit vector.
As shown in Figure 2, regardless of the position of the point p, we translate its normal vector n so that its origin coincides with the origin of the coordinate system, and the end of the unit normal lies on a unit
The normal vector for the arbitrary speed curve can be obtained from, where is the unit binormal vector which will be introduced in Sect. 2. 3 (see (2. 41)). The unit principal normal vector and curvature for implicit curves can be obtained as follows.
Normal vector definition A normal vector is a vector perpendicular to another object, such as a surface or plane. Often we refer to a unit normal vector \vcn, which is a normal vector of length one.
In particular, a unit normal vector. Obviously you can figure out a normal vector you can just divide it by its magnitude and you will get the unit normal vector. So I want to figure out at any given point a vector that's popping straight out in that direction. And has a magnitude one. So that would be our unit normal vector.
