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:
- Uncategorised
Syntax
- Syntax:
- vector1 vectorCrossProduct vector2
- Parameters:
- vector1: [x, y, z] Array
- vector2: [x, y, z] Array
- Return Value:
- 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]
