Description

Description:

Dot product of two 3D vectors.

2.14

Since 2.14 any count of numbers is valid, but both arrays must be same length.
Before 2.14, the first argument had to be vector 3D, or 2.00 2D (With z coordinate defaulted to 0)

Groups:

Math - Vectors

Syntax

Syntax:

Parameters:

vector1: Array of Numbers

vector2: Array of Numbers

Return Value:

Number

Examples

Example 1:

1.22 Algorithm:

Vector1 = [x1,y1,z1]; Vector2 = [x2,y2,z2]; Result = (x1 * x2) + (y1 * y2) + (z1 * z2);

It is recommended to use vectorDotProduct instead of BIS_fnc_dotProduct.
