Answer 1

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.

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?
