# Using an array of empties to for ex. make the depicted unusual open ended ternary graph?

Can an array of linearly equally spaced empties be used in such a way to take the offset distances (of every copy from the original) and then create another linear array whose elements would be offset from the original by putting the aforementioned distance values through a function ?

The next step would imply connecting the corresponding empties, the connections representing the pink lines in the graph.

OLD DESCRIPTION from a different point of view

Translating x values to y via f(x) as usual, but without treating x and y as coordinates, only endpoints of finite (pink) lines.

I looked for other solutions before coming back to Blender, but since it is an all out graphical application, and Python based, as are some of the other options which seem too formatted/specific in application, there's no reason not to ask if it's possible.

Since this question is much simpler then the previous which was solved by @lemon , I'm confident the answer will come, as I actually dissect the methods used there.

• I do not understand this question. Are there perhaps examples of similiar projects on the internet, which we could refer to? – Leander Oct 7 '19 at 14:28
• I don't think so, I've searched far and wide, and since nobody seems to be using the "ternary diagram" in this way, there is no formatted value input system that would allow the creation of the depicted graph. The crucial functionality needed to make this work is the generation of a list of vertices (along the yy axis) based on a list of vertices on the x axis. After some more thought I believe this is doable using animation nodes. (Doable even without using any of the established axes). @lemon showed me the AN light on an earlier question, but I didn't follow it diligently. – t8ja Oct 8 '19 at 18:00
• So you actually want to construct your figure as a geometry with python? – Leander Oct 8 '19 at 18:14
• Maybe it's easier (on my brain/memory) with animation nodes, but taking into account that any action can be scripted in Python, I accentuated Python. Yes, though I don't see any other way. What troubles me is that I haven't yet seen anyone spawn a wikipedia.org/wiki/Line_(geometry) within 3D view. – t8ja Oct 8 '19 at 18:28
• I'm confused, a line is infinite. Geometry (vertices) are going to be finite. Do you actually want geometry? Or are you talking about OpenGl/bgl. – Leander Oct 8 '19 at 18:30

• SY with a numerical entry of sqrt(3)/2, followed by
• ShiftCtrlAltS Shear, Z axis, X ortho, by tan(pi/6)
