    The singer from UK indie pop (?) band Everything Everything self-studied over three weeks this app along with Blender and some othe stuff to make a very stylised, glitchy music video the other week.

    He posted "Thanks for the help, guys!" messages in several Reddit forums. It was weird. "Wait, that's your band?" "Yeah, I'm the singer." "Oh, you sound great keep going!" These guys have sold out rather large venues in the UK. Anyway, this seems to have turned in to an endorsement of the band. Ok, yes it is. But I swear this isn't the singer again.

    For those with laptops or who don't have Nvidia GPUs, Meshroom can be used for free in the cloud using Google colab https://github.com/alicevision/meshroom/wiki/Meshroom-in-Goo.... I created this scan using this technique and I only have an integrated Intel GPU: https://sketchfab.com/3d-models/parvati-cantor-arts-center-a...

    If anyone would like to see a Meshroom scan, here's a fire hydrant I 3d scanned in Downtown Portland, Oregon: https://socialhome.network/media/uploads/2020/04/30/94efe3d3...

    I photographed it on my iPhone 8+ and used Meshroom to generate the mesh. The turntable animation was done in Blender.

    I'd be very interested in a comparison Meshroom vs. RealityCapture (which seems to become the standard in non-free photogrammetry).

    Was this always open source? Somehow in my photogrammetry journey I’ve heard of this and not tried it. I guess I assumed it was proprietary. Anyone have any comments on how this compares to COLMAP? Looks like better UI at least.

    Also anyone interested in the subject check out http://reddit.com/r/photogrammetry and http://reddit.com/r/3dscanning

    Fun software, easy to use. Was able to scan my kid's stuffed animal and reproduce a small 3d-printed version of it.

    I'm interested to try it.

    I've been watching people do photogrammetry for a while now, but the results have seemed really bad. When you remove the texture, the underlying model always seems off. This is important for doing object->mesh->modify->3D-print workflows.

    This implementation looks a bit better than the rest.

    They ever get around to HIPifying the CUDA bits?

    There’s a free photogrammetry app in the iOS App Store called turn3d. It’s a bit rough around the edges but does the job

    It seems like this has good promise, but scale is random on the output.

    I've been looking for a good way to make a customized face mask using photogrammetry and my 3d printer, so I'm going to give this a shot. The only issue will be scaling the model so that my head is the right size for the modeling process.

    If you don't want to mess with setup etc check out https://get.display.land/ which will let you download and do whatever you want with the resulting models.

    CUDA-only :(

    Has anyone tried it? I've been trying for a while to find a way to 3D scans stuff to 3D print but the quality of the final file has always been so crappy that I didn't even want to waste time and filament printing it

    Great software.

    Now if only they can start to catch up with Reality Capture in terms of speed...

    Is it possible to do this programatically?

  • by andybak on 5/9/20, 3:39 PM

    Odd that the title didn't use the word "photogrammetry" which is what most people call this thing.

    No Mac = No go for me.
