Description

Description:

Unit vector, equal to direction from vector1 to vector2. In other words this command produces normalised vector between given 2 points.
To get a non-normalised vector, use vectorDiff.

Groups:

Math - Vectors

Syntax

Syntax:

vector1 vectorFromTo vector2

Parameters:

vector1: Array - vector 3D or 2D (since 2.00, z coordinate is defaulted to 0)

vector2: Array - vector 3D or 2D (since 2.00, z coordinate is defaulted to 0)

Return Value:

Array

Examples

Example 1:

[1,2,3] vectorFromTo [4,5,6]; // is the same as vectorNormalized ([4,5,6] vectorDiff [1,2,3]);

1.26 Algorithm:

Vector1 = [x1,y1,z1]; Vector2 = [x2,y2,z2]; Result = [ (x1 – x2) / (sqrt ((x1 – x2) ^ 2 + (y1 – y2) ^ 2 + (z1 – z2) ^ 2)), (y1 – y2) / (sqrt ((x1 – x2) ^ 2 + (y1 – y2) ^ 2 + (z1 – z2) ^ 2)), (z1 – z2) / (sqrt ((x1 – x2) ^ 2 + (y1 – y2) ^ 2 + (z1 – z2) ^ 2)) ];
