Dot Product

What is it about?

This page covers the Dot Product node of the Redshift renderer in Cinema 4D. It measures how parallel two vectors are — the mathematical heart of facing ratios, custom fresnel effects and light-angle masks.

Returns the inner product of Input 1 and Input 2 vectors, using the following formula: Input1.x * Input2.x + Input1.y * Input2.y + Input1.z * Input2.z
