Function: cross

Syntax

cross (<point1>,<point2>)

Type

point

Returns

The cross product of two 3-D vectors.

Parameters

• <point1>
  Vector u.

• <point2>
  Vector v.

The answer is computed as (u2*v3-v2*u3, v1*u3-u1*v3, u1*v2-v1*u2).

Examples

Get the cross product of two direction vectors (u and v), each computed from two 3-D points defined interactively

point u = dir3d(pcur,pcur)
point v = dir3d(pcur,pcur)
point dir = cross(u,v)
