ColorRamp (EX9.Texture)


I can’t figure out where the node ColorRamp (EX9.Texture) node could be useful.
I think I know what it does - it takes vector, multiplies the RGB values of the input texture with that vector individually, and then uses these three vectors as positions on the control texture. The pixel will then get the RGB values of these three positions. Right?

But in which scenario would I want that?

I see, this basically only makes sense with 1D textures, right?

Ah no, makes sense with 2D textures as well of course! Just understood the whole thing:

The line is drawing the From and To inputs onto the control texture, the other two windows are the input and output textures.
