Description
- 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. - Groups:
- Math - Vectors
Syntax
- Syntax:
- vector1 vectorCrossProduct vector2
- Parameters:
- vector1: Array - in form [x, y, z] or 2D (since Arma 3 v2.00, z coordinate is defaulted to 0)
- vector2: Array - in form [x, y, z] or 2D (since Arma 3 v2.00, z coordinate is defaulted to 0)
- Return Value:
- Array - vector [x, y, z]
Examples
- Example 1:
- Example 2:
- Example 3:
