Raw Renders

Great stuff!

As for the cauliflower, I actually got some pretty good results from Photoscan a few years back.



Not perfect, but I was amazed at how much of the detail it managed to capture. It does help that I rarely need or use the diffuse when I've scanned stuff, so I will often under-expose the images which gives Photoscan more information.

Or, as Peter suggested, paint the object grey or sprinkle talcum powder on it. I sprayed this lemon and orange with primer and then used some talcum powder to help knock back the reflections.



Of course, if you're pulling the diffuse from the photographs then this isn't much help!

Very nice.
How many poligons?Do you import into ZBrush to optimize?

And I am wondering about your photography setup in terms of light.

[Sbrusse]

Yeah I always wondered if you use some kind of tabletop that rotates with a fixed cam and light setup or if you pin the subject on a stick and navigate handheld around it to take all the shots.

Or any other way?

hi - very interested in this at the moment as well!

i tried using autodesk memento recently with mixed results... it certainly doesn't work well if your subject is a human and they are incapable of staying perfectly still!

@Sbrusse Just to be clear, do you guys mean Capturing Reality software? Versus Reality Capture.

that's the one.

be prepared for a bunch of buttons in the UI that don't work yet. but getting some good results, at much larger scales than anything else could handle.

Capturing Reality is the company, Reality Capture is the software

New age for 3d modeling, will it kill all the 3d modeler in future? i am just wondering...

When a client gives you a sketch he made on a napkin or finds a photo online and says, 'make it just like this, but more awesome and twisted inside out' the scanning approach will not be really helpful
For a lot of 'filler objects' it does seems like a good method.

Yeah this is where i see the best use for arch-viz. All that random clutter you see around you that is hard to replicate (or rather, too boring)
Even just on my desk here there are 10-15 objects that I would scan to use as clutter in scenes.

[chriserskine]

I've been using it for context modelling for larger sites.

its a lot easier to do a heli shoot and run it through some photogrammetry software.

doesn't really replace normal modelling for things up close. and generally needs a fair bit of clean up. but combination works well.

hmmm...both of the comments has comfort me a lot, thank you for your vision and sharing.

Some more stuff. This is all done using a turntable, a Sony A7 full-frame camera with a prime 50mm lens, and some softboxes to flatten the lighting.

I checked out Reality Capture, but at $15,000 for a perpetual license, I think I'll stick with Agisoft. Not quite ready to remortgage the house for software.

[chriserskine]

these look really good.

are you taking them to zbrush or anything else before max?

you can get promo version. its only limit is 2500 photos or laser scans max. but supports the things you get in advanced version of photoscan (good for GIS reference things).

I think the software needs more work before you would want to get a perpetual license (since subscriptions on top of that too). there are lot updates that are needed. its beta 1 software atm.

but for what you are doing with tabletop stuff, i think photoscan is good. and more things work. when you get to large scale things that fact its a lot faster makes a big difference.

[BBB3]

I didn't see the promo. I'll check again.

My workflow varies depending on the assets. If the model is very heavy, with lots of surface details that needs to be preserved, I do retopo in ZBrush and bake diffuse, displacement and/or normal maps from the high-res asset. If the asset is such that I can decimate it and still retain enough details, I generally don't go through ZBrush.

The wood bowl was originally scanned but then remodeled from scratch in Max. I just used the scan as a projection object to bake the maps.

As for the earlier discussion about where scanning fits, I would say it's great for entourage and props that I don't have the skills or time to model myself. But I also use it to get a modeling aid when doing, for instance, larger furniture when I don't have proper blueprints.
