vectorCrossProduct

Description

Cross product of two 3D vectors.

In layman's terms, if you have a polygon (surface) defined by 3 points, you can find a normal to it (just like terrain surfaceNormal). To invert direction of the normal, swap arguments around.

Syntax

vector1 vectorCrossProduct vector2

Parameters:

• vector1: Vector3D or Vector2D - since Arma 3 v2.00, z coordinate is defaulted to 0 if not provided
• vector2: Vector3D or Vector2D - since Arma 3 v2.00, z coordinate is defaulted to 0 if not provided

Returns: Array - vector [x, y, z]

Examples

Example 1

_vector = [1,1,1] vectorCrossProduct [2,2,2];

Example 2

_vectorUp = [0,1,0] vectorCrossProduct [-1,0,0]; //[0,-0,1]

Example 3

_vectorSide = (vectorDir player) vectorCrossProduct (vectorUp player);

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