Slight tangent, but does anyone here have recommendations for a good serialization format for 3D models for the web? Think for loading into Three.js. Ideally something that can be converted to/from Collada. It seems like a lot of the standard file formats are quite heavy. Edit: glTF? Not sure how good tooling is for this yet, but looks promising.

Gtlf is where we are all headed but you’re right, the tooling hasn’t caught up yet. Google Draco[1] is also an important new development. Compressed meshes and point clouds! It works well and has three.js examples.

I have no idea why no one is talking about Draco anywhere. It’s a hugely important new tool. MPEG for vectors!

I think FBX works well with three.js too.

There are lots of sites full of 3D models. - Thingiverse - 3D Content Central. http://www.3dcontentcentral.com - GrabCAD. https://grabcad.com/library - 3D Part Library. http://www.3dpartlib.com/ - 3D Warehouse. https://3dwarehouse.sketchup.com The ones for CAD are more useful, because they usually have the dimensions right. You download those because you want the parts to fit. For competitive reasons, they tend to be…

Of course there is a huge varierty in types of '3d models' - from stylised low-poly for games etc. (what this seems to be), to refined 3d art, accurate models of existing buildings, parametric architectural product models and shader effects (e.g. https://www.shadertoy.com/).

As a side note the sketchup 3D warehouse used to be owned by Google in fact, and some of its best attributes (geolocated buildings) were lost in the google process (as part of their switch from using sketchup to populate 3d maps, to 3d city views from composite aerial photos and lidar).

Cool, but I don't really get the intended audience, if there's any specific? Games? I guess VR/AR stuff, like Google cardboard. I like that they have the C64: https://poly.google.com/view/9Qc5EtYmJry although they call it "Keyboard (not combined)".

AR/VR would definitely make sense. Especially in some sandbox mode where you can place models around you, having a quickly accessible library of low poly models integrated would be awesome.

Draco looks exactly what I need actually -- thank you!

In hindsight, sketchup probably would've been a great asset for Google to still own

It's a shame they sold it. It still has the highest modelling capability / difficulty ratio of any 3D software I've seen. Also the 3D Warehouse was a load of fun.

I used to think this, but interestingly, after learning several other CAD platforms, you realize both how limited SketchUp is and how the usability is really not substantially different with the huge exception of the onboarding experience. (Not to even get in to what garbage geometry it barfs out.)

There is a traditional UI paradigm in the CAD world which is totally divorced from the desktop UI world that's become ubiquitous in the past few decades. SketchUp was succesful mostly because it rethought all that based on what laymen are familiar with. But Especially at it's absurd new price-point, I think the argument for SketchUp's existence would go away entirely if Rhino just added a waaaaay simplified default workspace, enabled a sensible set of snapping options and the gumball by default, and maybe added a handful of contextual cues for common manipulation tools.

Anyone know what the poly-limit is for uploaded models? Would really like to see them support GLtf from Khronos as an input/output(API) file format. That's one of the formats we're watching closely at http://realityzero.one I may just do a test upload of some of our scanned models later on. In fact have been scanning a load of Jurassic era fossils that will be part of the supporting cast for a late YC application sub…

Interesting business. Model cost was killing me 10 years ago when I ran a virtual world company.

Do your company just handle static models right now? Animated ones are a whole new level of difficulty. How about generating levels of detail on the model? So many more things that are challenging! Good luck.

Shameless plug, the three.js fbx converter supports a number of formats including Collada: https://github.com/mrdoob/three.js/tree/dev/utils/converters...

The other day I needed a simple coffee mug model to preview a design I was making in Adobe's new Dimensions CC app (basically easy way to add textures to models and envs for product pre-vis).

All the sites I found with quick googling had either unfitting models or weird file formats that Dimensions app didn't accept. But searching "mug" on Poly just now and importing the .obj worked just fine. Slap that design on there, render, review and order custom mug from a nearby printing shop with confidence that the design will fit fine.

Just one use case for free and quality models.
