How Does Perlin Noise Work?

[@arvedsteuer6994]

This is the only video, that could explain it to a simpleton like me. This Channel and especially video deserves more love

The dot product is also often calculated as vector1.x * vector2.x + vector1.y * vector2.y

Thank you so much, I understood everything thanks to your clear explanations

[@AntonXCMlite]

Thank you! I made this algorithm overnight

[@Yuvaraj-t6u]

the best explanation

[@piyushmeeedits]

i don't understand the interpolation part, the interpolation gives 0.131 if we calulate but you wrote 0.265 for top part?

Hey! where is the thumbnail

[@marouanbellari1380]

I was working on a perlin noise script in rust and used this video as my reference, it works great thanks for the super comprehensive guide! Due to the linear interpolation formula though, all points that are also grid points (such as say (3.0, 3.0)), will always create 0 values as their percentages are 0 (if I understood the video correctly). Is this normal or are there workarounds for this?^^

[@marouanbellari1380]

nevermind, i found the issue elsewhere. As the formula is using (1 - percent) * n_1 + percent * n_2 it wouldn't give a 0 value but just have the n_1 value as a result.

@marouanbellari1380 I'm glad you got it working!
