Applications & Usability
In 3D space, how do you find a direction perpendicular to two others? The Cross Product Calculator computes the vector product (A × B) of two 3D vectors. The result is a new vector that is orthogonal (90 degrees) to both input vectors. This is a critical operation in physics for calculating torque, magnetic force, and angular momentum.
Calculation Methodology
Game developers and 3D artists use cross products constantly to determine "surface normals"—essentially figuring out which way a polygon is facing so lighting can be calculated correctly. Engineers use it to analyze stresses and rotational forces. This tool automates the complex determinant math (y1z2 - z1y2, ...) to give you the precise XYZ components instantly.
Fun Fact: Physics Fact: The direction of the cross product follows the "Right Hand Rule." If you curl the fingers of your right hand from vector A to B, your thumb points in the direction of the result!
