BernieB Posted January 17, 2020 Share Posted January 17, 2020 I'm curious about modelling a honeycomb lattice around a sphere. I was inspired by Rode's Stereo VideoMic X. Rode Stereo Videomic X Quote Link to comment Share on other sites More sharing options...
¢hris £und Posted January 17, 2020 Share Posted January 17, 2020 Started to play with this, and I kept coming up with a few pentagrams... Hmmm... if you take a closer look at the image, there are occasional pentagrams too. This is pretty manual... but, start with a Geodesic sphere, with a number of subdivisions of 4. create to size. Then pick an arbitrary location (I chose center top) and start deleting segments so that you have a hexagram left over. Adjacent to that, do it again... and keep going. Again, you will run into spots, that the only option is a pentagram. Too, you may need to experiment with higher number of subdivisions. I only tried a value of 4. and it may be possible, that I run into trouble somewhere that neither a hex or a pent will fit.... Hope this helps, and hope even more that someone else will come up with a more clever idea. ¢£ Quote Link to comment Share on other sites More sharing options...
¢hris £und Posted January 17, 2020 Share Posted January 17, 2020 6 subdivisions is the magic number, First eliminate the pentagon "fills" this gives you a kind of nucleus to work around. It really helps to have your pick tool to "crossing always" that way you only need to capture the center of each hex or pent that you want so that you can delete them. Or, you can use what I set up as a starter. HexiSphere.fmz.zip cheers! Quote Link to comment Share on other sites More sharing options...

Bo Atkinson Posted January 17, 2020 Share Posted January 17, 2020 (edited) Great work there guys! And now for the lazy way 😁 Version 6x had the original Attach Tool which did result in a decent looking frame version, (which hides the imperfect alignments), but the model is all done with just a few clicks.

Bo Atkinson Posted January 17, 2020 Share Posted January 17, 2020 However looking closely at the extracted primitives the flaws of alignment are seen: Quote Link to comment Share on other sites More sharing options...
santa Posted January 17, 2020 Share Posted January 17, 2020 This could also possibly work using a texture. Find a seamless hexagonal pattern, derive transparency and bump maps from it and simply map to your object. Not a modelling solution, but it may be good enough.

I'm not fully convinced a texture approach would work. My goal was to replicate the structure of the Rode VideoMic. So I want to have the lattice wrap around another sphere. In the future I also intend to make the inner sphere semi-transparent, to test the lighting and detail within. Quote Link to comment Share on other sites More sharing options...
BernieB Posted January 18, 2020 Author Share Posted January 18, 2020 I also plan to simulate the foam texture of that microphone, but through Maxwell Render. I find their library is limited, so I hope to try developing a new entry someday. Quote Link to comment Share on other sites More sharing options...
