Hi guys, thanks for the tips. Following the 0626's tutorial, I was able to repeat the same project. However, when rendering it, the orthogonal bars do not appear; only the arrows are rendered. How could I get around this? Also 0626 and Happypolygon, in this project is it possible to project the two waves in a translucent ortogonal planes, as shown in the figure at the beginning of the thread?

Hello ZEROSIXTWOSIX, thank you very much for your recent contributions. I'm really close to finishing the animation now. However, in this last video, there's a detail that I'm unable to resolve. I've reviewed the video countless times and tried everything within my reach to eliminate the mismatch of the lines (as shown in the figure), but I couldn't succeed. In the video time interval between 6:55 and 8:30, you perform a series of bake operations, but when I repeat them in my project, I haven't been able to achieve the same result. Could you please indicate where I might be going wrong? What could I be overlooking? Many thanks, Eudes laces-wave-part3-com-alembic.c4d

Hello everyone, I would like to animate an electromagnetic wave in which the electric field oscillates in a plane that is orthogonal to the plane of oscillation of the magnetic field. But instead of employing waves in a line, I would like to be able to animate arrows, which can periodically reverse their direction, as shown in the gif below. Also, to further demonstrate that both waves oscillate in orthogonal planes, I would like to project them on a translucent plane, like the one in the second gif. As the only renderer I have available is Picture View, native to Cinema 4d, I'm not sure I'll be able to render the transparency of these planes. If anyone has any tips, either regarding modeling or rendering the planes I would be very grateful! Bests, Eudes

Hi ZEROSIXTWOSIX, thanks a lot for your help. I finally managed to model the curves. Now, I'm trying to animate them like you suggested at the end of the third video. I made alembic of my objects and animated them. I notice that while the closed loops could be replicated as they should be, the circles orthogonal to the loops are not replicated. That is, over 90 frames, only the original circles propagate, no replicas are generated. I tried all my knowledge of Cinema 4d combined with all your suggestions in your videos and still I couldn't finish the animation correctly. I'm sending you my file so that, if possible, you can help me finalize it! Thanks a lot for the support, Eudes. laces-wave-part3-com-alembic.c4d

Hello ZEROSIXTWOSIX, Thanks a lot for the help! I'm redoing your tutorial step by step. In this last video I'm having trouble understanding the command you used at exactly 1min12sec to replicate Circle.1. I assume you were using a mouse (but I'm using the touchpad) and I don't know if there's any auxiliary key I should press to perform this command. Could you tell me how to execute it? Bests Eudeus

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.
