Question by sweta001 · Apr 09, 2018 at 09:16 AM · physicsunityeditorline rendererfieldmagnetic

Magnetic field line issue in Unity c#,Magnetic field line in unity using c# scripting,Magnetic field line

Hello all,

I am trying to create magnetic field lines in unity. and there are so many lines which I want to manage at runtime as shown in this link which is created in unity only.

https://www.youtube.com/watch?v=9WSZF13Ih2Y

I am not able to understand that how these lines are managed through the script and what should I do to get similar output as shown in given link for magnetic field lines.

Please help me if anyone is able to understand and provide solution for the lines.

I'm pretty sure that the lines use some kind of spline implementation between the closest opposite poles, and calculating the line positions between all the poles according to physics of magnetism. The lines in the first part are probably drawn with LineRenderer, while in the second I think the field results are written into a render texture, then drawn behind all the objects (based on the more precise results, drawn onto all pixels, and that it takes longer).

@Harinezumi ya, it can be spline implementation. but can you tell me that how this line position is calculated between poles according to physics magnetism? because if I manage all these line endpoints individually then it is taking so much time and through that, it is not coming perfectly as magnetic field line. so, is there any equation that I can apply on line renderer and which helps to generate lines using physics law.

That, my friend, is the difficult part of this problem: finding the appropriate calculation for the magnetic field lines.
This post might be a good starting point, although lower it is mentioned that the calculation changes if there are multiple poles. The wikipedia article on the topic mentions that the representation changes with resolution, so I think one approach could be to sample the strength of the field at a specific resolution, and draw the lines where it is the strongest. Finally, as with all electromagnetism, the equation must be possible to derive from $$anonymous$$axwell's laws, although it might not be trivial.
Sorry I don't have a solution, physics simulation is always tricky and hard.
