thank you for this wonderful software, I can't believe free version has basically all the features, 50 images is more than enough for me
Hi srbinbwe! Thank you for your kind words! :)
very good tutorial and very impressive software. there are several woods nearby full of tree stumps just waiting to be turned into 3D objects as soon as i have done the next 3DF tutorial on photography!
Thanks for the very good tutorial. (As already noted below) Although a little hard for me to understand you at first, it made me listen better and I look forward to learning much more with your help. I recently bought a Creality Ender 3 for $200.00 (First machine) and'm having a blast printing gargoyles and soap dishes (Plus the hairy mane lion) but there are so many dimensions to 3d printing that it can be hard to grasp all the possibilities.
Thanks again,
Jim
Perfect results! Much more reliable than Agisoft and simple to use. Tutorials are very clear and easy to follow. Best photogrametary software out there! Great work guys!
you probably dont give a damn but does someone know of a method to get back into an instagram account?
I stupidly lost the account password. I appreciate any assistance you can give me
@Cody Kyle Instablaster ;)
@Eliseo Mustafa thanks so much for your reply. I got to the site on google and Im trying it out now.
Takes a while so I will get back to you later when my account password hopefully is recovered.
@Eliseo Mustafa it did the trick and I actually got access to my account again. I'm so happy:D
Thanks so much, you saved my account !
@Cody Kyle Happy to help :)
Woah, ok this is incredible!
You guys are amazing ty.
Thanks for making this I'm trying out 3DF
FEATURE REQUEST:
Please introduce the ability to mask in 3D mode instead of 2D mode.
Ideally, we should be able to mask 3D volumes after the sparse point cloud is generated but before the dense point cloud is created. If we were given the ability to select the positions for good or bad data from the 3D model, we would only have to select 3D volumes ONCE rather than selecting 2D pixels potentially hundreds of times in the Masquerade masking tool for 100+ image collections.
Once the software knows each camera position in 3D space, project each 2D image on the included volume to AUTOMATICALLY mask the entire 2D image set.
In the example shown in this video, it would also be useful to exclude all pixels colored green. This would be especially useful if we were capturing photos with a Hollywood style "greenscreen" backdrop. If we could select color spectrum ranges for the masking tool, that could be very useful.
Lastly, thanks for making a great product. I'm a very happy customer!
Hi Stylac, thank you for your kind words and your feedback! Although this would certainly be a cool feature (for example in body scanning) it may not work as well for turntable. We will keep in mind though, so please keep sharing your ideas :)
Good point! One thing I want to try is taking a bunch of pictures through a fence then erasing the fence from the 3-D model so it doesn't obstruct the view of what's beyond the fence.
The existing Masquerade tool can do that.
Show! Excelente.
how do i put the pictures into the program
Hi. I just downloaded the trial of this software. It looks to be what I need. I plan on purchasing it. However, do you plan on doing a follow-up video for this? It appears many of the options/menus have changed. I've had to pause/rewind several times to find where the options/menus are. It would improve the learning curve greatly. If you already have done so, could you provide link(s)? Thanks!
Hi! Thank you for the feedback! Indeed Zephyr gets a lot of updates so you may occasionally find some slight differences in the tutorials. We plan in making updated videos of course :) however going back and redoing all videotutorials is not very easy - so while you may be a bit disoriented with the videotutorials, if you see discrepancies in the UI check also our text tutorials or manual from 3dflow.net as they are updated much more frequently, you should be up and running quickly ;) or contact us at support@3dflow.net or join our discord server discord.3dflow.net for realtime help :)
Thank you for the informative video! :)
Great first tutorial. Is there a portable version of Zephyr?
Can video file be imported in this software for creating 3D model, such as, head, object,terrain. Thank you.
Hi I'm a student and i don't earn , I'm a big fan of 3df Zephyr free edition .
Because it's FREE and gives high quality 3d photogrammetry model
I would love to consider a paid package of 3df Zephyr if i start earning .
Zephyr is the best.
Greetings,
As in 3df zephyr to show only the mesh without textures.
Also know if possible, a better quality setting, for example, to scan with a bust of a park character.
I have good quality photos and the result is acceptable, I note that autodesk-recap with only 100 photos gives a better quality
and I have the pro version of zephyr.
I love Zephyr 3DF more than other software and I want to get the best out of it.
Thank you very much for the time.
Hi,
you can toggle color and lighting using the icons in the toolbar if you wish to show only the mesh.
Quality settings can be quickly changed via the presets (i.e. from default to high details) in the wizard, or as you learn deeper how the software works by changing the advanced parameters.
You can share the dataset with us if you wish. Contact us on our forum or on our facebook group 3Dflow academy if you'd like us to take a look at your dataset.
very good video
I assume that "Dense Point Cloud" is now called "3D Model Generation" in the current version right?
Hi! Yes - 3D model generation will output both the dense cloud and the mesh in one single step (doing dense and then mesh). You can eventually use the advanced menu if you want to process only the dense cloud, however it is recommended to also generate the mesh if you want to export a dense point cloud, as the photoconsistency step will also improve the dense point cloud (but not if you do the step manually from the advanced menu)
Help! Can’t get the dataset using the link above
don;t know why the end of the link is replaced by ...
Curious - I shot video of an object (as a .mov), and when I go to import, either it wont see the video, or, if I drag / drop, 'next' is greyed out. I have tried H.264 and TIFF as compression... Is there a 'best' setting to conform video to that 3Df Z likes the most?
Hi Gouldeyecandy, you need to select "Import pictures from video" - regardless of the extension though, it depends on the codec. It should work, but you can contact us at support@3dflow.net if you're having issues!
I think the dataset is not accessible
me too
hello, i am new with Zephyr, but i am facing some issues, i followed the tutorial video, but i am getting a white screen in the middle and no images is showing up , any idea please? thanks
Hi Faouzi, make sure you're running the latest drivers for your video card and if you're using your computer via remote desktop that your monitor is plugged in, as some remote desktop software may have issues with 3D rendering if the monitor is not plugged in.
What is the way to shot something like a donut or a loaf of bread when you want not to lose the bottom side of the object ? What is the workflow there.
Hi Antonis! You need to use masking if you are moving the subject, unless you can create a perfectly plain background (hard to do, but possible). Make sure to not alter the geometry of the subject as well (e.g. with a soft body such as it may be a pastry)
What is the best lens to use on a DSLR for the least distortion? 50-85?
Hi Art Cid! It really depends on the subject and the distance, regardless, zephyr is autocalibrated and will automatically process the distortion - in fact,never use undistorted images with zephyr! 50-85 works great :)
Witchcraft! (but I love it.)
Good software but i have a problem with my photos.Why my images are scanning with the background?Should i mask the background with some black material maybe?
Hi Michal! If you are moving the object, then zephyr has no idea if you wish to reconstruct the background or the object. If this is the case, you need to mask out the background - you can use the included 3DF Masquerade tool (See videotutorial 3). If you want to share the photos with us (forum, facebook 3Dflow academy, discord) we'd be happy to help you figure it out :)
+3DflowChannel No,i dont move an object,only my photo camera.I try to use the Masquerade tool:-)
then if it is just some unwanted backround in the reconstruction, it is probably just a bounding box that is too wide. Simply rescale it to your liking before the MvS phase
Hey!
I'm not able to export the model.
It requires a API key.
I'm working on Free software.
Can you please help me?
Thanks in advance.
Hi ravjot! Sketchfab is a third party service, so if you want to export to sketchfab you will need to input in Zephyr the Sketchfab API key. Otherwise, simply export in any format on your computer.
when i finish i will be able to export to 3d max?
this is compatible to 3d max ?
Hi! Yes of course! You can export in many formats , including fbx, obj, ply, and more!
hey guys. After starting a new project, the screen doesn't show advanced option where i can click NEXT.
please tell me why
Hi germain! If you mean the advanced settings, the dropdown menu is always in the top right corner, but if you mean you don't have the next button (bottom-right) most likely you're running on a very low resolution screen. In this case, try the fullscreen mode (view->fullscreen). If neither these are your case, can you be a bit more specific? If you need to post a screenshot you can do so over our forums at forum.3dflow.net ! Hope this helps!
I only load in 8 pictures and get a Error :(
Something went wrong, please run the processing again. Try to take more photos or change parameters.
I have a feeling that 8 pictures might be to little ? I have only 8 angles
Hi Sean, 8 images are not a lot, depending on the subject it may be also very difficult. Feel free to send us the photos to support@3dflow.net and we'll be happy to help!
textured mesh export is not available in trial version?
Hi! the Free edition does not allow for mesh export but textured mesh only. If you get the trial edition of the Lite version, you can also export non-textured mesh :)
How can I use the mesh in Zbrush. When I import the obj file Ive generated with zephyr it instantly crashes when I use the dynamesh feature in zbrush
Hi Michael,
there should be no issues for Zbrush to handle Zephyr-generated meshes. Can you share with us ( info@3dflow.net ) the mesh and details of the process you are following? Make also sure to export in local coordinates if your model is in geographic coordinates (this happens automatically if you have GPS data in the exif, i.e. if you shot images with a phone), as many modelling software have issue with those type of coordinates (not sure if this is the case, just a hunch :) )
Grazie! Volevo chiedere se fosse possibile un tutorial su un oggetto complesso come un piccolo edificio
Ciao Archemi! Grazie a te! Sicuramente faremo un tutorial per gli edifici, sia per quanto riguarda per le tecniche di acquisizione che tips & tricks per il processing. Essendo però un argomento un po' più complesso, probabilmente non sarà tra i prossimi, ma sicuramente lo faremo :) grazie del feedback!
Why doesn't UA-cam translate things like this? Actually, it might not matter. If I copy/paste it into Google, it might just tell me about a flying goat that can't sing for some reason.
yes, a detailed tutorial, with demo footage, for buildings (small and large) would be great. this is exactly what i need as well as quite complex interiors. this short 3DF video, ua-cam.com/video/PIf3GK_WjXE/v-deo.html, is not really much help in terms of what to do and anyway, it is mainly an interior. btw, thank you to 3DF for what looks like a great product. i am about to try it.
Hi Julian, sorry for not replying earlier - we missed your comment! Thank you for your feedback - if you have facebook, we regularly do polls on what the next tutorial will be, so we'll try to include your suggestion as well as soon as we can!
I can't select by triangle
okay figured it out... my bad didnt have mesh generated yet
How To speed up the textured mesh génération?
Hi Felix, you can either use a lower resolution or deselect certain cameras from the textured mesh generation wizard page.
@@3DflowChannel gracias
Super low sound volume makes the video useless sadly.
Hi Jonas, we're sorry to read this! We suggest using headphones and/or English subtitles. Besides, you can contact us anytime at support@3dflow.net if you have some questions on the basic workflow, we'd be happy to help!
no mac? Ever? :(
Hi millolab! Unfortunately a mac version is not currently in our roadmap, sorry!
Great tutorial but with an incredibly strong accent, speaking English quickly......it makes it very very difficult to understand! Borderline impossible in places. Might be worth slowing down employing a voice-over person. Just an idea. Nice product though!!
Hi Graeme, thank you for the feedback - newer tutorials are indeed spoken by a native British person :)
I have to slow down the video to actually understand what you're saying. The accent and the speed at which you are talking makes it difficult to understand you. Sorry.
Hi Calvert, thank you for your feedback, in more recent tutorials we have an actual native speaker doing the voiceover :) simply enable the closed captions for these older videos and you're good to go!
@@3DflowChannel Thank you. This has been very helpful.
very very bad
