How would you implement the following as Vex within a Point Wrangle? 


x = x

y = y*cos(rx) + z*sin(Rx)

z = y*-sin(rx) + z*cos(rx)

one way:
@P.y = (@P.y * cos(rx)) + (@P.z * sin(rx));
@P.y = (@P.y * -sin(rx)) + (@P.z * cos(rx));

Assuming rx is a float values…

It's worth noting that the VEX cos() function expects radians, unlike the expression cos() function which expects degrees.

Hi,

as a small addition, I've figured out, that it might be better to to save @P into a seperate variable to avoid that some values of @P are overwritten too early.
