  1. Dear @EAlexander, thank you very much for the suggestion. I did exactly as you suggested and the result was excellent! Hugs, Eudes
  2. Hello everyone, I would like to animate a light cone (from relativity theory). This is nothing more than a cone of revolution. I want the animation to start with two lines inclined at 45 degrees, then rotate these lines around the vertical axis, and as they rotate, they should produce a translucent cone. Something like what's shown in the link below. Could you help me with the best strategy for this animation? Thank you very much, Eudes. https://sketchfab.com/3d-models/light-cone-space-time-model-ee42d146c1e94f3b8804a1230c4dfe10
  3. Hi @HappyPolygonthank you for that. The result was amazing. Bests, Eudes.
  4. Hello everyone, I'm trying to make an animation of light rays passing through slits. In one situation, the slit is large and the rays pass straight through it. In the other, the slit is small and the rays diverge (diffract). It turns out that the rays for diffraction must be wavy and not straight. (See image below) I tried to do this by employing emitter and associating a wavy object with it. To make it look like lightning I made it long. But with this I can't limit its length using the appropriate option in the emitter. As soon as it reaches the screen with the slit, it should stop (as is the case in this case), but that is not the case. How could I do to limit these rays to the screen? Another thing (important), how could I make them diverge from the slit? Is there a deformer capable of doing the job? Thank you very much, Eudes. wavy-ray.c4d straight-ray.c4d
  5. Hi HappyPolygon, I'm trying the "Emitter+Tracer+Deflector" approach suggested by Zerosixtwosix. I believe the modeling is satisfactory, but as I anticipated, it's proving too difficult to me to find a setup for rendering. The materials and lighting seem to result in something completely different from what was modeled (see below). It's also different from the video posted earlier as a reference. Do you have any tips to improve this project? eudes.
  6. Hello, @happyPolygon, I believe it's possible to animate the ray satisfactorily (something like in the link below would be excellent). The most challenging part might be finding materials to render the light and surface realistically.
  7. Hello @HappyPolygon and @ZEROSIXTWOSIX, thanks for the suggestion. I contacted the RocktLasso, but unfortunately their plugins do not allow changing the direction of the light beam. I also wrote to Nitro4d staff but received no response. I'm going to try something using the tips from ZEROSIXTWOSIX and I hope I get an interesting effect, including in the rendering. Eudes.
  8. Hi HappyPolygon, thank you for the link! Do you know if there would be any plugin incompatibility with newer versions of C4D (2023.1 in my case)? I tried installing the plugin, but it doesn't appear in the list, even after restarting the program. Eudes
  9. Hello everyone, I would like to animate the propagation and reflection of a ray of light in two and three dimensions (as illustrated in the figure below). Do any of you have any suggestions on how I can do this animation? Could Emitter work to animate the light ray? If so, how should I define the surfaces to reflect the ray? Bests, Eudes.
  10. Hi @Happypolygon and @Cerbera, thanks so much for your support. Happypolygon, I tried to adapt the doformer you suggested by simply copying it into the Cerbera project but that didn't work. It didn't seem to apply to objects as it should. Cerbera, I'll try to render following your suggestion! Thank you very much, Eudes.
  11. Hello Cerbera, your suggestion is excellent. However, I have two questions. One is in relation to a refinement I'm trying to make in the modeling of the wave. In physics, a photon is usually represented by a modulated wave, as shown in white at the figure below. I tried to change the waveform by multiplying the parameter X(t) by cos(t*PI) but it didn't work. Is there another way to do this? Another issue, when trying to render the error below is shown. Does any function you used in your project require a specific renderer? Thank you in advance! Eudes.
  12. Hello everyone, I need to create a small animation like the one in the video. This is the production of X-rays. The electrons (little balls) are launched against a metal part, and during the collision, X-rays (phótons, the little waves) are formed. I would like to know from you what is the best way to animate these little waves that represent the X-rays. Any suggestions are welcome! Thank you very much, Eudes.
  13. Hello @happypolygon and @ZEROSIXTWOSIX, I come to share with you the final result of my animations. Below are the links for two different timings, illustrating each of your contributions. If you'd like, I can make references to you in the video description; just provide me with the information you wish to share (names, links, etc). Thank you very much for the support; I was very pleased with the final outcome. Best regards, Eudes Happypolygon https://youtu.be/DeOkVlie8zE?t=437 ZEROSIXTWOSIX https://youtu.be/DeOkVlie8zE?t=471
  14. Hey 0626, now it worked flawlessly! I made sure to complete my animations before getting back to you. As soon as I upload the video, I'll share it with you and @Happypolygon so you guys can get a glimpse of how your work has truly elevated mine. Bests, Eudes.
  15. Hey 0626, as you can see bellow, in my project the very first step already leads to an error. The mismatch appears whenever I associate the "Connect" object, regardless of whether the 'weld' option is active or not." Thank you very much for your time. https://youtu.be/yhzUHHf2hI4
  16. ZEROSIXTWOSIX, thanks for that! It worked perfectly. Bests Eudes
  17. Dear ZEROSIXTWOSIX, Once again, I extend my gratitude for your invaluable assistance with this project. From the standpoint of the theory I am explaining in my video, it complements the previous project you've been helping me with (essentially, the loop/circle project represents the electromagnetic wave near its source, while the oscillating wave and orthogonal planes depict the electromagnetic wave as it propagates). Unlike the other project, I was able to faithfully reproduce this one. The project turned out to be excellent and highly customizable. With it, I can animate various wave parameters, which would be absolutely fantastic for presenting the content! But as I mentioned earlier, I am encountering difficulties in rendering the vertical bars that, together with the arrows, form the oscillating pulses. I've tried some desperate alternatives, like using sweep and spline circles, but they were not successful. Since I am truly eager to incorporate your project into my video, I was wondering if you could assist me with this rendering issue. I would be immensely grateful for your further support. Once again, I am more than willing to credit your channel or any of your possible graphic business activities. Thank you so much for considering my request. Warm regards, Eudes
  18. @ZerosixtwosixHello ZEROSIXTWOSIX, First and foremost, I want to express my sincere gratitude for the time and effort you've dedicated to creating the impressive electromagnetic wave animation. It's truly a valuable educational resource, particularly considering how challenging it is to produce such animations for those of us without 3D graphic design skills. I've spent considerable time, perhaps even days, attempting to achieve the same results as you, but unfortunately, in this project, I've been unable to match the waves, as I mentioned in my previous message. Regrettably, my video on electromagnetic waves is now almost a month overdue, and I've come to the conclusion that I cannot replicate your tutorial or project. I believe there might be a technical issue in my version of Cinema 4D, as I've diligently followed your steps precisely, yet the desired outcome continues to evade me. As it has been a considerable amount of time that you and I have invested in this project, I would be deeply disappointed if I couldn't make use of this incredible content you have produced, if I couldn't make it beneficial for many students who want/need to learn this topic of Electromagnetic Theory. Therefore, I am earnestly requesting that you kindly share your project with me. Your assistance would be immensely appreciated, and I cannot thank you enough in advance for your help! This project is a significant hurdle for me, and I'm eager to finish my video and continue with my YouTube lessons. Additionally, if you find it agreeable, I'd be more than happy to give you proper credit for the project, acknowledging your YouTube channel or any other business activity you're involved in. Thank you very much for your attention and consideration. Warm regards, Eudes (my e-mail: fileti.fileti@gmail.com) (my channel: www.youtube.com/c/VerveCientifica )
  19. Hi Happypolygon, the bars I'm referring to are those that connect the arrows (see the attached figure). They don't appear after render... As for the suggestion to render separately, it's a nice insight! I will do it this way. Bests Eudes
  20. 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?

  21. 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
  22. 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
  23. 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
  24. 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
