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
Sanofi Genzyme - Atopic dermatitis
client : Business Stratégie Communication Category : Development
Augmented reality application for the occasion of a trade show for Sanofi laboratories via Business Stratégie Communication. The application is an internal application for doctors on the show to understand the mechanisms of atopic dermatitis.The application was used mainly on iPad tablets, but it was also available for Android.
The app uses Vuforia for 2d marker recognition (2 markers only). I had to develop a camera movement smoothing system to avoid AR-related tracking shakes when moving too far away from the marker. The refraction shaders were made using Shader Graph (see my tests about it).

Smartphone refraction
Category : None
Refraction simulation and more generally transparency on smartphone is a rather expensive luxury. However, thanks to Shader Graph, it is possible to quickly prototype a shader which allows this at a lower cost. This is what I tried to produce on this test.
A parametric triplanar noise is used for the deformation of the vertices, but also the normal map, as well as the deformation of the background video texture. This texture is then applied to the object on its emission channel and its albedo with a bit of Fresnel. The result is far from being a true refraction of course, but for the smartphone, and given the few resources that this requires, it works pretty good.
I am using this shader in a production being finalized in augmented reality which will not fail to appear very soon here.

Rocket Car
Category : None
Little demo of augmented reality by object recognition. The object recognition is for this moment less precise than by marker, but it works pretty well.This has been done with Unity 3d (2017.3.1f1) and Vuforia.
VR Physic (HTC Vive)
Category : None
The physic managment brings a lot to a VR scene. In this example, I've added a dynamic reaction to the object in order to simulate a rubber effect with MegaFier with Unity 3d (HTC Vive).

Element 3d - test 2
Category : None
A new test of the new exciting after effect plugin : Element 3d from videocopilot.net. The multi-object system is very interesting. Unfortunatly, the textures management has much room for improvement mainly for imported objects. But this tool provides a 3d result in a very fast way.
Freedent inflatable object
client : La Rue Category : Graphics
Adaptation of a 3d model and rendering for an inflatable object for Freedent from La Rue agency. The job was to edit the 3D object to respect the constraints related to the manufacture of inflatable (about 1m height), and make HD renders for customer validating. Members of the characters that were in volume had to be projected as textures.Credit modeling: Freedent
Augmented reality with Android
Category : None
I have not tested the Android Augmented Reality in Flash ... the 3d is still quite sluggish on android. Recognition algorithms would put the CPU to its knees without any doubt. However, the last test with Unity impressed me, and I decided to test it with the excellent library of Qualcomm augmented reality for Unity. The system is still unstable, i expected much more, so the tests are encouraging. (Android 2.3.3 (gingerbread) - Samsung Galaxy S)
