cross — calculate the cross product of two vectors
vec3 cross(
|
vec3 x, |
vec3 y); |
dvec3 cross(
|
dvec3 x, |
dvec3 y); |
x
Specifies the first of two vectors
y
Specifies the second of two vectors
cross returns the cross product of two
vectors, x and y,
i.e.
$\begin{pmatrix}
{ x[1] \times y[2] - y[1] \times x[2] } \\
{ x[2] \times y[0] - y[2] \times x[0] } \\
{ x[0] \times y[1] - y[0] \times x[1] }
\end{pmatrix}$.
