(cross product)
Operators
The Cross node (also called a Cross Product) takes in 2 vector values and returns the cross product of the 3rd vector.
A cross product is basically the direction of the 3rd vector by using the other 2 vectors. The math behind it is somewhat complex but it can be used to get a direction of the other needed vector. See Also has more information for specifics and mathematical concepts.
Some applications that this node can be used for:
- Calculating Normals on a surface.
- Collision Detection on a surface.
- Physics Simulations, including Orientation and Rotation.
- Texture Mapping, especially for bump mapping or other effects that rely on surface orientation.
- Animation and Rigging, which includes calculating bone transformations and constraints.
Inputs
A (Pseudo-Generic)
The first vector value.
B (Pseudo-Generic)
The second vector value.
Outputs
* (Pseudo-Generic)
The returning and resulting vector direction (dependent on handedness).
