IntroductionWith the release of ARKit 2 in 2018, Apple added a bunch of new features and APIs for AR development. One of the features is an enhancement to the already existing Quicklook API. Quicklook has already existed within iOS for a while now where we could quickly preview documents like PDFs and CSV’s along with text files and Images.You might have used the Mail app on iOS to preview attachments. That is possible by using Quicklook.Now with ARKit 2, Quicklook has been expanded to work with Augmented Reality using ARKit. This means the capability to preview and see augmented reality content and also sharing them like any other file.This is made possible by USDZ, which is a new file format for rendering AR Models. AR QuickLookThis feature can be implemented in two ways. In the first method, we can use QLPreviewController to embed these into a native iOS application in XCode. This makes integrating AR Content within an app easier without having to worry about ARKit and all that implementation.The second method is using Web AR through the Safari browser. This is what we’ll look at in this article.How does it work with WebAR?This is made possible by using a new file format called USDZ. Built-in iOS apps, such as Safari, Messages, Mail, News, and Notes, use Quick Look to display USDZ files of virtual objects in 3D or AR. This also includes real-time reflections and shadows.This Quicklook view can then be embedded into any website. When the webpage is opening in Safari, iOS will detect the file and prompt an AR dialog.AR QuickLook then handles the task of rendering the model into the environment, taking care of light conditions, scanning the surface, placing the object into the environment, and holding its place even when the camera moves around. In this article, we’ll look at the USDZ files and how to convert your 3D Models into USDZ format. In the following Part 2 of this article, we’ll upload this article on a hosting website and create a demo webpage. Finally, we’ll host the webpage on GitHub for free and experience it using the Safari browser.What Is USDZ?USDZ is derived from a format called USD which stands for Universal Scene Description. USD allows content creators to create a 3D scene by composing” many modular data sources (files) together into successively larger and larger aggregations. This format is from Pixar. For larger scenes, it becomes harder to organize different files together. This is where Apple in Collaboration with Pixar introduced the USDZ format. USDZ is basically an archive of the USD scene file and the additional files. The Archive can also be a zip, which is compressed. Hence, the Z in USDZ.Thus, a single USDZ contains all the mesh data, binary data and all the textures of the model. The anatomy of a USDZ file is as follows.Converting Existing Models into USDZNow, how do we convert our models into USDZ?It’s fairly simple, Apple provides two tools to convert your models. First, is

We love USDZ and the AR Quicklook functionality within iOS. We also love Cinema 4d. However, it’s not easy to create a USDZ file directly from Cinema 4d. What follows is a detailed, tech-heavy, walk through of my process creating a Stern Pinball spinner USDZ, starting with Cinema 4d.The PlanI want to create a USDZ file for AR Quicklook on iOS using the 3D tool I am most familiar with: Cinema 4d. It’s most efficient for me to construct the geometry in C4d, do some texture mapping in Body Paint, and deal with the available outputs and conversion utilities to create the final package.My goals are:To take advantage of Augmented Reality by constructing the object at real-world scale.To make the object more engaging with animation.To explore the process needed to generate and apply PBR materials to the model.Avoid using online conversion tools like Vectary or Sketchfab.Complete Spinner Assembly With Switch (Left Side) (from: PinballLife)The objectI want to create something that has fairly simple, repetitive, mechanical movement. It should have a few different parts and textures. I love pinball, so a pinball part was an obvious choice.I chose a spinner from a modern Stern Pinball machine.In doing some quick googling, I found these solidworks files by Joe of Using these will save some time, and will prove that we can adapt a cad-like file format to USDZ through conversion.Cinema 4d Studio can import solidworks files natively. Alternatively, you can export the .SLDPRT files to .stl files through Fusion 360. Sketchfab outlines that process here.Cinema 4d can import .stl files. At that point it’s just a matter of re-arranging the objects and ensuring they are set to the correct scale. In Blue below, I’ve ensured that the project is set to 1mm, and in Green the overall Y-dimension is approximately 60mm.We’ll address the magenta section in the Animation portion of this post.Tips for successYou must nest your objects under a single root node for scale and animations to work correctly. In this case, highlighted in Red, stern_spinner is a null object with the other geometry nested below it.That root node determines the position of the object in AR. You want it to be positioned at 0,0,0 with your geometry emanating from it. More than likely, you will need to fiddle with the axis to get it to look right.While the screenshot does not show it, I would recommend only a single level of child nodes. At some point in the conversion process (possibly to glTF?), I ran into trouble with animations when there were several levels of objects.Your nodes should also be named to be easily converted (and recognized): no dots, spaces, special characters, etc…Maybe this is obvious, but you should makeAR Quicklook definition and description - matthiashamann.work

2025-03-31Are set to 1.Then, I ran through the same usdz_converter process as before, but used the following command line options:xcrun usdz_converter spinner.abc spinner.usdz -a -l-a Generate a .usda intermediate file. Default is .usdc.-l Leave the intermediate .usd file in the source folder.This utilizes the options to create an intermediary, ascii .usda file, and does not delete it.At that point, I opened the .usda file with a text editor and edited the properties that made sense, such as:endTimeCode = 23framesPerSecond = 90startTimeCode = 0timeCodesPerSecond = 90Most importantly, however, is the endTimeCode. I essentially ‘trimmed’ the animation so that it looped correctly by setting the value to the final frame that I wanted, then sped it up by changing the framesPerSecond and timeCodesPerSecond values.I suspect that it is sub-optimal to have the ‘trimmed’ frames/timeSamples remain in the .usda file, so this should be investigated further.once edited, the .usda file can be converted to the .usdz file thusly:xcrun usdz_converter spinner.usda spinner.usdzSo, really, the conversion roadmap ends up being:.SLDPRT →.stl→.c4d→.abc→.usda→.usdzphew.Apple’s Retro TV sample USDZApplying Materials / TexturingI’m not going to describe the whole process of texturing objects in Cinema 4d. If you need help getting started, Greyscalegorilla will have what you need.If you have any tips for approximating PBR in C4d to match AR Quicklook, I would love to hear your feedback.If you’re importing 3rd party materials, or you are applying your own baked materials, I found this post extremely helpful. It does a great job explaining PBR, and where each texture should be applied.In my brief experience, I wasn’t able to get C4d to 100% accurately render the materials the same way as AR Quicklook, even with the Physical Renderer in Cinema 4d Studio. However, I was able to approximate things to a point that I was able to implement a process that worked well for me for exporting materials from C4d:Exporting Texture ChannelsI used UV mapping for all of my materials. Often times I had to manually manipulate those UVs, particularly for the brushed metal effect on the bracket.To keep your textures and .usdz in sync, remember to re-export your .abc file after you make changes to your UVs in Cinema 4d.The most efficient process for me was to bake objects with the relevant channels selected:BakingBy selecting your object, then selecting Objects>Bake Object, you will be presented with this screen:By baking all of the objects, with the relevant channels selected, then deleting any extraneous textures, you will have a uniformly named set of textures, prefixed by their node:barAmbient_Occlusion.pngbarMetallic.pngbarNormal.pngbarRoughness.pngbarSurface_Color.pngbracketMetallic.pngbracketRoughness.pngbracketSurface_Color.pngswitchAmbient_Occlusion.pngswitchMetallic.pngswitchNormal.pngswitchRoughness.pngswitchSurface_Color.pngtargetMetallic.pngtargetRoughness.pngtargetSurface_Color.pngAlternatively, you can use the Bake Texture tag on an object for more granular control of the channels that you are exporting. It’s output can be configured to match the naming pattern above.Finally, once you
