Hi all,
Just wondering if anyone might explain how to use the “reflect” function in Math Combine. I’m trying to negate a “speed” attribute should the centroid of the effected shape cross a set value limit.
Thank you!
Hi there,
It works by giving 2 vectors as arguments. One being the vector of incidence (so your ‘speed’/‘velocity’ vector), the other the ‘normal’ vector (the vector pointing away from your surface). It will calculate the right direction of the reflected vector.
Not sure if this makes any sense, so I made a small example to show how it works. Might be a bit complex with all the mathmix operations, so I’ve added a textDAT describing the math.
Hope it helps!
Cheers,
tim
