Calculate the cross product of two vectors

Declaration

vec3 cross(vec3 x, vec3 y)

Parameters

x specifies the first of two vectors

y specifies the second of two vectors

Description

cross() returns the cross product of two vectors, x and y. The input parameters can only be 3-component floating vectors. The cross product is equivalent to the product of the length of the vectors times the sinus of the(smaller) angle between x and y.
