Hello ZEROSIXTWOSIX, this solution was really sensational! This is the animation of electric field lines. But, for the project to be complete I would still need to include the magnetic field lines (the blue circles shown in the figure). Ideally they should be synchronized with the electric field loops (as indicated in the figure) but I think that if it's something too complicated to do, it could just be a set of circles that expand radially. Do you have any more effective suggestions for implementing these circles? Bests Eudes

Hello ZEROSIXTWOSIX, thank you very much for the excellent alternative! How could I render these lines? I tried using sweep + circle without success. There would be ways to make these lines translucent surfaces of revolution. This would give us an excellent 3D representation of the waves. Bests Eudes

Hello Happypolygon, how are things going? Months ago you helped me with this problem (the generation of an electromagnetic wave) and proposed this solution, which I think is very good! It's finally time to use your suggestion to produce the animation (that should be released at the beginning of next month). While working on your initial project, I noticed that the wave lines are not rendered (only the oscillating charges appear). So, I tried using sweep and circle to produce the curve. I managed, but it didn't seem like a good way out. In the photo below, the part of the curve that should appear in the image is just the one in the white region, but it also appears where it shouldn't (in the pink region). Could you tell me how I could get around this? Bests, Eudes

Happypolygon this is perfect. Very simple and effective. Thank you! Bests Eudes.

Hello everyone, I would like to animate the electronic cloud around an atom. Something as shown in the figure below. Each dot represents an electron. For this animation I would like these electrons to revolve collectively around the nucleus of the atom, all in the same direction. Could you suggest me the best Cinema 4d tools to make this animation? Bests, Eudes.

Hello Happypolygon, the animation I would like to make is like the one in the video below. But notice that in the video the lines remain static, when physically they should emanate from inside the magnet. So I considered the possibility of using an emitter.

Hi everyone, I would like to use emitter+tracer to animate the magnetic field lines crossing a closed loop, as shown in the figure below. However I was not able to find any force to make the lines to diverge. Do you have any tips on how to do this? Bests, Eudes.

Hello Cerbera, thanks for the correction. Now I got it. The idea of this project is that the sum of all these vectors would result (approximately) null. But if you look carefully at the result you will see that there is still a net orientation. If we add all the vectors, the result will point to the right. That is, there is no perfect randomization, where the vectors point to all sides in approximate amounts. What parameters should I change to effectively randomize these directions.

Hello guys I'm trying to randomize the orientation of objects in a cloner. For that I'm using "Plain" with "Random Field", following the tip in the tutorial below. However I haven't been able to make it work. Could you help me to find my mistake? Thank you very much Eudes. dominios.c4d

Hi guys thanks for the tips. My animation (to explain Ampere's Law of electromagnetism) was excellent.

Hello Happypolygon, your method is very interesting. But would it be possible to smooth the closed curve so that it has no corners? Cerbera, I managed to clone the cylinder onto the spline but I haven't been able to make them evenly distributed. How could I do that?

Hi Cerbera, no I didn't. But this is a perfect solution for me. Eudes.

Hello everyone, I would like to illustrate a generic polygonal curve (like the dash line in the figure below), made with small straight segments. However, I only get a satisfactory result for a circle, when I use a polygon spline and adjust its number of sides to around 25. To get a generic curve I tried to use deformers like bending, but that didn't work, because the segments stretch and they are different sizes. The next idea is to morph the polygonal curve into a continuous curve, illustrating the application of differential calculus. Thank you for help, Eudes

Hi Cerbera and Bezo, thanks for the tips! Both have similar aspects. Bezo, in your file I tried changing the number of turns in the coil but with no sucess. How could I do that? eef

Hi Cerbera, thanks for the tips. Some of them I had already tested and some I had not. In one of the attached files I tried to morphize a straight saline into a helix. Despite trying, following tutorials, I still couldn't get the animation to work. When editing the helix (initial and final radii) I was able to do the morphing but I ran into two unwanted problems: 1) This method produced non-physical results, leading to a helix whose wire length is much longer than the original wire. I think it's okay to have some difference, but the difference observed with this method was very high. 2) Another problem is that I can't align the circular salt lines in the turns of the coil.

Hello everyone, I would like to make a video, like the example below, where a wire turns into a coil (this is a well-known phenomenon in electromagnetism: the magnetic field in an inductor). After studying the case, I found myself with three distinct difficulties. 1) What is the most effective tool in this case to animate the morphing process? 2) How to link the curved arrows (or possibly lines, which would be even more accurate) to the wire/spool movement during morphing? 3) How to transform the lines that wrap around each of the coil turns into integrated lines over the coil as a whole? I tried pose morph > splines > sweep, but unsuccessfully. Please, any suggestion is very welcome! Bests, Eudes. sample.mp4 morph-wire-to-coil.c4d

Hi Imashination, sorry for this rookie fail. Now it's working perfectly. Thanks. Eudes.

Hi CBR, sorry. I really should have sent the project file in the first message! Here he is now. Thanks. fio-curvo-e-reto.c4d

Hello everyone, I want to render my project with two arrows, which indicate the direction of the magnetic field. However, when rendering the animation the arrows (and only them) do not appear. I went through something similar before, when I couldn't include an object's glow effect in the rendering. For these arrows, I've been trying to render them as buffer objects but I think I'm doing something wrong. Could any of you help me with this? Maybe there is a link to some video tutorial... Bests, Eudes.

Hi everyone, thank you so much for your support. I got a very satisfactory result with the tips you gave me. In particular the video that VIZN suggested to me was very helpful! Bests Eudes.

Hi guys, thank you for help me. I'll try all these suggestions. VIZN on: "If you wanted to enhance this look in post all you would do is render out a black & white mask pass of the spheres, then use that in compositing app to add further blur / softness to the light." Would you have some tutorial video on that procedure? Happypolygon, I'm using R25 version.

Hello Happypoligon. Thanks for the tip. I have tried to employ it in various ways but the result is always the same. The images below show what I would like to get. When rendering with “Render View” ok! But when rendering with Picture View, the most I get is a yellowish background that wasn't there before Buffer (and no glow effect) Any idea where I could be going wrong?

Hey guys, thanks for the tips. I've been working on this project for the last few days and all I could come up with was align a cylindrical object with my circular field lines (as well as the lead wire) and try to create a luminescent material with a glow effect. This seemed satisfactory to me, but I have not been able to render the glow effect. I've tried several options in "Picture View" and nothing works. The curious thing is that it appears when I render in the "Render View". I think this would be a trivial thing to do with RedShift, but unfortunately I don't have a license to use this software. Please, if you have any suggestions or a more effective method, I'll be happy to know! Bests, Eudes. fio-reto_0001.c4d

Hello everyone, I would like to animate 3D lines with a glow effect to indicate the direction of circulation of a magnetic field. I would like something like shown in this video (jump to time 2:21). Does anyone have a tip on how I could achieve a similar effect using Cinema 4D? Besides, even the lines (which are elliptical sections), what would be the best way to make them? Thanks in advance. Eudes.

Happypolygon, the exact timing of the synchronization I think is arbitrary, but from your initial design I think it would be better if every time the particles crossed each other, a circle is released. Thus, each loop of the electric field would have a single magnetic circle line associated. By the way, magnetic field lines really are planar circles, not spheres. Regarding the arrows, I agree that they are of little relevance to the electric field loops. However I believe they are useful for the magnetic field. One circle oriented clockwise and the subsequent oriented counterclockwise. Maybe we don't really need to use an arrow, maybe some kind of movement that indicates the field line circulation in one direction or another (small spheres for example, I don't know…). Eudes
