Those are artefacts. Splats are not perfect around reflections.

Love these!

I also have them on x: https://x.com/DanyBittel/status/2055624819941483005 I thought direct image links are more welcomed here.

Oh, that would be amazing! The photos are also available and some people definitely take it for a test ride. However.. This dataset with the stacking is far from generic.

The light doesn't need to be completely flat like what you'd do when scanning it more traditionally, for meshing. The problem is when the highlight is sharp and reflects it's surrounding. You could remove it, with cross polarization.. But then it wouldn't look realistic anymore.

There is actually still a Lytro type camera for industrial application available: https://raytrix.de/ Too low res, too expensive for my use case unfortunately.

That's what I thought too.. supersplat has no way to set it to CC0 otherwise.

Thanks! I use the computer only to setup the shot, adjust lighting make test stacks of different angles. If everything is good, I disconnect and capture to the memory stick. During the shooting I only adjust the beginning or end of the rail a bit, so everything is in focus at some point. Triggering (manually) the rotary disk still happens from the computer.

I glue mounted the strawberry on three nails and used pins to secure it. I have to think about your idea.. I don't think friction would be enough to hold it in place.. it would probably be hard to knot the top onto something too, as that's where the light is: https://i.imgur.com/vIjw6pc.jpeg

But I'm always experimenting with the mounting, thanks for the inputs.

Yes it's shoot in front of a bluescreen.

I usually use PostShot.. but the quality was not very good. I want to try LichtFeld but my Graphics Card has too little memory.. so I reached out on twitter, some people ran tests and Mykhailo got some better quality out of it so I took his training. You can d/l the COLMAP dataset for free and try yourself.

I like that they are sort of between a photo and a 3D model. Nothing quite like it.

This is an interesting question. There has been some attempt to model the camera better than just a pinhole camera, that could work. https://dof-gaussian.github.io/ https://github.com/leoShen917/DoF-Gaussian

My take.. at a macro scale, the dof is usually so small, that it's hard to get a reliably track. So you'd need some sort of way to tell that these stacked photos belong into a series, and then you sort of are doing focus stacking :-) I do think the alignment algorithm could be improved. Maybe the approaches I linked could be used to make a much more robust focus stacking algorithm, that also corrects for 3D geometry. That would be really cool!

It's an artefact unfortunately. Gaussian splats have no concept of refraction and have a hard time dealing with reflection. Highlights, usually so so. Something I always wrangle.

Thanks! We have two compressed formats, the sog by PlayCanvas and spz with sparkjs. Both now support LODs and compress really well.

I posted some pictures.. takes only 20 min!

It is in fact still on it's mount and slowly rotting / molding.. for a second capture :-)

Yes mounting.. and I can't quite reach all the way from below.

I have done 2x macro (an ant).. and want to try 5x.. but as you get closer, the depth of field becomes really shallow. You can do focus stacking but you risk that the individual areas in focus are less ideal aligned and the tracking can't make any sense out of the geometry anymore.

I just posted some images.. I have actually done my studio, (quality is.. let's say painterly ;-): https://superspl.at/scene/0a3916cd

And it only takes 20 Minutes to shoot all 7920 photos, the Z8 is crazy fast.

It was mounted at the bottom.. and I can't quite reach it with my camera. Might have to try some two pass way.

Very well said, also many other non bees are also pollinators, such as butterflies, some beetles.. even ants. Any flower is a hotspot of life.

Tangential, have a look at a Gaussian splat of a honeybee I recently captured: https://superspl.at/scene/3ae6a716

From the article:

...AI is currently the subject of great enthusiasm. If that enthusiasm doesn’t produce a bubble conforming to the historical pattern, that will be a first.

If you want to see a mosquito and it's proboscis up close, I recently scanned one into a gaussian splat: https://superspl.at/view?id=b4cbf5d6

This sounds a lot like Learned helplessness: https://en.wikipedia.org/wiki/Learned_helplessness

It all kind of depends on each other. More light, means longer recycle times on the speedlights or higher iso, more noise. Longer exposure isn't an option with speedlights, using continuous also has it's downsides, things may start to shake..

You can definitely feed camera intrinsic (lens, sensor size..) and extrinsic (position, rotation..) into the SfM. While the intrinsic are very useful the extrinsic not actually that much. In no way can you measure the rotation good enough, to get subpixel accuracy. The position can be useful as an initial guess, but I found it more hassle than worth it. If the images track well, have enough overlap, you can get exact tracking out of them without dealing with extrinsic. If they don't track well, extrinsic won't save you. That was at least my experience.
