Yes, through the .setAttribute() method we refer to the attribute of the .BoxGeometry() method called 'position'. If we want to add our own attributes, we will use the .getAttribute() method.

https://code.sololearn.com/WVedD2DzahRW/?ref=app now this working but this is weird..it seems like for vertex position i have to name my attribute exactly as "position" and cant declare smtg like "attribute vec3 position" in vertex shader..it works for other attributes though(like "a_colors" in this code)..but i would like to know why?is this intentional or a bug?
