Remarks Platform Requirements Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8.Vector Projection is a method of rotating a vector and placing it on a second vector. Hence, a vector is obtained when a vector is resolved into two components, parallel and perpendicular. The parallel vector is called the Projection Vector. Thus, the Vector Projection is the length of the shadow of a vector over another vector.

The vector is of form $(0,0,z)$ with z < 0 and we can simply invert it before applying the formula above. As shown below this can be exploited to get a branch-free implementation. The vector is the zero vector $(0,0,0)$. "perpendicular" doesn't make much sense in case of the null vector. If you interpret it as "dot product is zero" than you can ...
