✨ CROSS(3G) ✨

okay bestie, welcome to the cross glow-up 💅 this is the 3G manual page, and we're about to calculate a cross product together like it's the most iconic thing that's ever happened to you.

🌸 NAME 🌸

cross — calculate the cross product of two vectors ✨

🎀 DECLARATION 🎀

here's the receipt, no cap, exactly how you call it:

vec3 cross(vec3 x, vec3 y);

dvec3 cross(dvec3 x, dvec3 y);

🦋 PARAMETERS 🦋

  • x — specifies the first of two vectors 🫶
  • y — specifies the second of two vectors 🫶

💖 DESCRIPTION 💖

so basically, cross returns the cross product of two vectors, x and y, i.e.

$\begin{pmatrix} { x[1] \times y[2] - y[1] \times x[2] } \\ { x[2]
\times y[0] - y[2] \times x[0] } \\ { x[0] \times y[1] - y[0] \times
x[1] } \end{pmatrix}$

the way it's literally just three little lines of multiply-and-subtract and it ate that whole thing up 😭🔥
