Sanofi CPLF 2022 Hololens
client : Business Stratégie Communication Category : Development
Hololens application for Sanofi Genzyme (via Business Stratégie Communication) on the occasion of the CPLF 2022 exhibition in Lilles (France). The application was developed for the Microsoft headset and intended for doctors at the show. It allows, thanks to augmented reality, the doctor to discover and diagnose a case of severe type II asthma.
The video capture does not pay tribute to the device because unfortunately Unity's URP (Universal Render Pipeline) is not properly supported for transparency at capture and black spots appear. Unfortunately, this does not correspond to the holographic effect that can be observed in the helmet. Let's hope that Microsoft/Unity fixes this pitfall quickly.
The MRTK library makes it possible to quickly and fairly easily use the features of the headset (management of hand controllers, voice recognition, iris detection, display of 3d in augmented reality space, close and remote interactions, scan of 3d environment, 3d occlusion etc...).
Made with Unity 2021.1.28f1 + MRTK 2.7.3 on Microsoft Hololens 2 headset
Unity raytracing (sequel)
Category : None
Still in the context of my investigations on raytracing in Unity using the latest package (still in preview) of real-time raytracing based on the most recent Nvidia GPUs, here is a small and very short test video. The lack of time, but especially the lack of stability of the functionality, and the incessant crashes did not allow me to push much further the tests.
I had planned a lot more, but, at the time of writing this post (February 2020), raytracing under Unity is still in pre-release. It is therefore absolutely not possible (and I confirm) to use it serenely in production for the moment unfortunately.
Nevertheless, the results, although succinct and limited, are still encouraging. Hopefully Unity will (finally) produce an efficient real-time GI system ... and one that works ... maybe with this techno ?
I'll test this further when the raytracing will be much more stable.
Configuration used :
Nvidia GTX 1080m
Unity 2019.3.0f6
HDR 7.1.8
Unity fallback realtime raytracing
Category : None
Unity recently added real-time raytracing to its latest version (2019.3.x). This is mainly due to the significant advances of Nvidia. Until now, this functionality was only available on the latest RTX graphics processors from Nvidia. However, recently, this functionality has been extended to older GPUs (but with slightly lower performance of course).
The result is still far from perfect, but rather encouraging. If we consider that raytracing under Unity is still in the development phase (beta), we can expect many more developments.
On this demo, the reflections are clearly exaggerated, but it seems that by decreasing them, they disappear. Perhaps it is due to the still groping Unity library, or the limited fallback on my GTX 1080. Anyway, the indirect reflections in real time, the refraction, as well as the reflections are rather impressive.
A few years ago, I had tested a library unfortunately abandoned by its developer (Rove 3d), hoping to be able to render high quality renderings at runtime. Perhaps Unity's real-time raytracing is a first step in this direction ...
More tests will follow on this exciting feature.

Rove 3d is an asset for Unity 3d wich can make (nearly) realtime renders in pathtracing. The result is very similar to what Vray can make. The asset is still experimental and lacks a lot of features, but it's very promising. The render is very good, very fast, and one can imagine original apps specially for interior rendering. I'm working on a video about this wich will be available soon.
Thulhagiri water bungalow

The acquisition of the pro version of Unity allows me more fantasies in 3D developments. Here is a virtual tour of a water bungalow on Thulhagiri Island (Maldives) in North Male Atoll.Technically, I developed a lot of items (custom shaders, various unityScript, selective glow, pictures display...). A Mac & PC version is available and also an online version (requires webplayer Unity).

Unity 3D is a very powerful 3d engine, but what about mobile ? I haven't had a chance to test it on iPhone, but Android is quite impressive. I quickly modeled a simple model, coded a few lines in order to manipulate the object, and I must say that so much fluidity is quite exciting. My previous tests with an 3d flash sotfware engine were rather sluggish. The first tests with Molehill Away3d are very impressive. I look forward to compare both engines ....( Android 2.3.3 (gingerbread) Samsung Galaxy S).
