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)) ];
