smartphone development

BSC asked me to develop a clinical case study for Convatec in order to highlight their products. The case can be viewed on internet via webGl. It is mac/pc compatible, but also tablets/smartphones.

Questions are asked such as multiple choice question, drag'n drop ... and the answers are counted. An avatar gives a full answer and development to each question.

Statistics are displayed to the customer via a backoffice that I have developed for the occasion (number of connections over a period, statistics of connections by access from urls over a period, level of progress on the quiz, time spent on the module, ratio of right/wrong answers on each question, number of attempts per unique user, conversion rate on webinar access, statistics of os used).

The module has been developed with Unity 2021.1.11f1 (webgl), and the backoffice was developed with php / mysql / html / jQuery. The graphs are produced with CanvasJS.

As part of an unfortunately aborted project, I worked on an interactive event for professionals from the pharmaceutical / medical sector in Qatar. Sanitary conditions meant that the show experience could be replicated online for guests who were invited and who could not attend.
I worked on the 3d development part. The show has been virtually modeled to allow the user to move around and access the various features and sections of the site (chat, live video conferences, various resources, etc.). We used Furioos technology for 3d. This technology allows real-time 3d streaming. Concretely, the 3d is calculated on the Furioos servers and displayed to the users. The undeniable advantage is that it is possible to obtain a "PC" type rendering quality on mobile. The result was quite interesting.The project was therefore developed with Unity 3d 2019.x URP + Furioos.
Unfortunately, for reasons of timing, the 3d version of the project was aborted.

I just finished the development on a POC ("Proof of Concept") for a 3d tool intended for opticians. I was in charge of the 3d part. The principle is simple: the user places dots on the scanned face of the client (by the iPad's Lidar system), algorithms (developed by Lunetic) then allow the placement and choice of the sizes of glasses in a catalog depending on the data collected. The customer can therefore visualize his face with the glasses of his choice.
The tool is of course linked to a database (models, colors, sizes etc ...) and it allows to generate a basket, take screenshots and place an order to send the result to the customer.The application was developed by Moonrise in Swift for iPad. The Unity 3d module that I implemented has been integrated and dialogues with the native layer.

This professional application is reserved for opticians. Technically, the 3d part was developed with Unity 3d 2020.1.17f1 in URP and exchanges are done in json and xml.

Still as part of the development of the exhibition hall of the Galerie de l'Alpe in the Alpine Garden, at the Col du Lautaret in Villar d'Arène (05), Le Naturographe asked me to model a stylized scree in 3d. This resin structure is just over 3 meters high.
The mission is an extension of the stylized root layout, as well as the virtual reality application for Oculus Go.

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.

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.

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.

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).
