Visible Fields

Mode

name: mode, type: Enum, default: Add

Defines the function.

Values:

Title	Name	Deprecated Name	Description
​Add	​Add	​add (a+b)	​Adds the two input vectors.
​Subtract	​Subtract	​subtract (a-b)	​Subtracts the second vector from the first one.
​Cross	​Cross	​cross product (axb)	​Computes the cross product of the input vectors.
​Ortho Project	​OrthoProject	​project a to plane orthogonal to b ((bxa)xb)	​Projects the first vector onto a plane orthogonal to the second vector. r = ((b x a) x b) NOTE that the input vectors are not normalized.

Normalize

name: normalize, type: Bool, default: FALSE

If checked, the Result vector is normalized.

Flip to Half-Space

name: flipToHalfSpace, type: Enum, default: None

Defines one of six coordinate half-spaces available according to the three coordinate axes x, y, and z.

If a given condition is not met, the vector is inverted, i.e., flipped by multiplying each coordinate with (-1).

Values:

Title	Name	Deprecated Name
​None	​None	​none
​Pos X	​PosX	​positive x
​Neg X	​NegX	​negative x
​Pos Y	​PosY	​positive y
​Neg Y	​NegY	​negative y
​Pos Z	​PosZ	​positive z
​Neg Z	​NegZ	​negative z

Vector 1

name: v1, type: Vector3, default: 0 0 0, deprecated name: vectorA

Sets the first input vector.

Vector 2

name: v2, type: Vector3, default: 0 0 0, deprecated name: vectorB

Sets the second input vector.

Result

name: result, type: Vector3, persistent: no, deprecated name: vector

Shows the result vector.
