Cross
2D/3D

Cross[vector1, vector2] returns the cross product of the direction vectors of the two Mech vector objects.

• In Modeler2D, Cross returns a scalar.
• In Modeler3D, Cross returns a vector.
Mech's overloading of the built-in Cross symbol has no effect on its usage in other Mathematica code.
• See also: Cross, Direction, Dot, Magnitude, SkewSym, Unit.

The cross product of two 2D vectors is defined as a scalar by Mech. This is really the Z component of the cross product {a, b, 0}Cross{c, d, 0}.

Cross can handle Mech vector objects directly, and take advantage of possible simplifications. Consider the cross product of two vectors in the same local reference frame.

Dot can also handle Mech vector objects directly for the same advantage.
