hi guys...this might be a silly question but i really try my best to understand maths around box3 and i discovered a lot of rules that made me a better user of box3, but my question is this:
i don't understand the point color gradient vector direction from a point on the geometry surface, in the description it says it's a tangent but i don't get it very well, if someone can make it clearer (with some illustration). thanks

also what is the difference between point color gradient and point color gradient 3D?

i think it will be helpful to have an option like right clicking on a suboperator that outputs a vector then having the opportunity to show its vector direction in the viewport, thanks

Yeah, a simple way to view vector directions in box3 would be nice.

Point Color Gradient will give out vectors based on the change in color on an object's surface.
Whilst the Point Color Gradient 3D will follow the gradient of a 3D Texture Map.

I've attached a side by side comparison for both.

Right animation is the same, but box3 is reading the 3D noise.

Yeah sort of, the vector goes from dark to light.

thank you very much mr galagas, this is exactly i'm looking for...
box3 would easier to understand if vectors direction are well known, or shown in viewport, because once you know the direction of each sub-operator vector, it's easy to deduce the direction of vectors addition, product or subtraction...i hope something will be done in that direction in the near future.
