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.
VFX Graph underwater effect
Category : None
Still in the context of my Visual Graph tests from Unity 3d, I tried the point cache system. It still lacks functionality and a few bugs remain, but the whole thing works pretty well. The possibilities are numerous, and many explorations still necessary...
The underwater effect is mainly given by the movement of particles and especially by post Fx (fog, color correction, distortion, chromatic aberration, vigneting ...).
VFX Graph / Shader Graph
Category : None
A small test video of the new features offered by Unity 3d: Shader Graph and Visual Graph. Shader Graph makes possible to produce shaders fairly easily and quickly using a nodal system, and Visual Graph makes possible to create complex particle systems via GPU.
The big advantage of these tools is that they allow one to use the power of the graphics card (unlike the classic Unity particle system: Shuriken). Consequently, the available power is increased tenfold. Aesthetically, we can now consider some rather wonderful things.
I will perform a next test in VR, and also on a smartphone with the URP (Universal Render Pipeline) engine to see the result is also convincing.
Stylized root (Lautaret France)
client : Le Naturographe Category : Development
As part of the development of an exhibition hall for the Galerie de l'Alpe in the Alpine Garden, at the Col du Lautaret in Villar d'Arène (France), I developed, at a preliminary stage (during the design of the room), a virtual reality application on Oculus Go to help better visualizing the volumes, arrangements, and spaces.
The application was developed under Unity 3d 2018 (C#) for Oculus Go (LWRP).
(Excuse the poor quality of the video that was recorded on mobile via the Oculus. The linear color mode is causing problems when recording).
Dentsply Sirona
client : Business Strategie Communication Category : Development
Augmented reality application for a medical equipment manufacturer. The purpose of this application reserved for the company's salespeople is to present the different ranges of dental 3D panoramic scanners.The application allows, via augmented reality and a suitable marker, to present the product in volume, to be able to see it from all angles. But also, it allows to evaluate the software part with screenshots, videos and full technical descriptions.
The application has been developped with Unity 3d 2019.2.5f1 (C#) + Vuforia 2018.3.8 for iOs.
Cytomegalovirus (CMV)
client : Henri 8 Category : Development
Development of an augmented reality application for a pharmaceutical company. The goal of this app is to present the inhibition process of specific molecules on a CMV virus replication scheme compared to its normal replication cycle.
The app has been developed with Unity 3d 2019.2.1f1 (C#) + Vuforia for iOs (iPad).

Convatec experts
client : Business Strategie Communication Category : Development
Augmented Reality application for a pharmaceutical company. The purpose of this application is to test the therapeutic knowledge of health professionals, while highlighting the qualities of the product marketed by the company.
A series of markers has been produced. Each marker corresponds to a case study staged by 3d animations. A multiple choice is then proposed. The score is displayed at the end of the process.The application adapts to the power of the device on which it is used by adjusting the quality of the visual effects.
The application is an internal application reserved for an audience of professionals on iOs.
Institut du Monde Arabe
client : Moonrise Category : Development
On the occasion of an event, the Arab World Institute wanted to produce a PC application allowing users to play sports commentators by commenting on the greatest soccer moments of major Arab teams. Novice commentators are filmed and recorded during the broadcast of the action. The video is then played to appreciate the performance and compare it to that of the famous RMC's french sports commentator: Jano Resseguié.
The application was developed with Unity 3d (C#) for PC Windows
