Dot Product
This page documents the Dot Product node of the Scene Nodes system in Cinema 4D. It relates two vectors to a scalar — the mathematical core of facing ratios, angle checks and projections.
The mathematical Dot Product of two vectors creates a relationship between two vectors and a number, referred to as Scalar. Hence, the Dot Product can also be referred to as a scalar product. Interesting for us are the values, i.e., the lengths of the vectors and the angles confined between the vectors. The Dot Product is the result of the multiplication of both vectors with the cosine of the confined angles. The Dot Product of Vector 1 and Vector 2 = vector length 1 * vector length 2 * Cos(angle between Vector 1 and Vector 2).
