Bonjour, Hello👋🏻

I am Loïc,
Passionate software engineer in computer graphics & image processing, 
who occasionally composes music and makes some games.

About me

I started coding when I was 11 on the family computer, and it turned out I still didn’t get bored of it!

I was born, grew up and did my studies in Bordeaux, ending with a Master’s degree in computer graphics and sound processing. I then went to Prague for an international experience in research in computer graphics, and I am now based in Paris.

I have always worked in image synthesis, mostly with C++, GLSL and Unreal Engine, which I learned to hack to make it do even cooler things.

Beside work, I compose music and do game design with the same team for years. We already did 7 games, which you can find below.

For exploring my music side, it is this way!

Experience

My work experience so far. You can ask me recommendation letters and references and I will transfer them.

Image Synthesis Engineer @ MBDA

1.5 year at the vision department of MBDA as a software engineer consultant sent by Alten.

Relevant projects: 

- IR simulation plugin in a video game engine comprising various physical phenomenon (weather, physical materials, Planck's law, sensor model)

- Starry sky modeling to assess its impact on the image processing algorithms of a missile interceptor

- Efficient sensor image transfer over network

- Python module to find good matches in a materials databases according to optronics and thermal data

2023

Research Assistant in Computer Graphics

Funded by PRIME European doctoral network.

2 main projects: machine learning method to optimize fluorescence measurements, fog modelling from NASA measurements.

Two co-authored publications.

Research presentations at tech summits and outreach events. Attended optics courses and gave some shading language courses de Masters students.

Despite the apparent success of the beginning of my PhD, I made the difficult decision to end it and join the industry.

2022

Two internships @ INRIA (team MANAO)

2019 (2 months): Rendering wet materials. Developed a new workflow for improving the appearance of wet materials (Substance Designer and GLSL). Results lead to my first scientific publication.

2022 (6 months): Optical modelling of plant leaves.
Implementing multi-layered materials in renderer (CUDA and C++), 3D reconstruction of plant leaves from INRAE scans, blender parametric modelling of leaves structures (at microscopic level).

2019

Electrical Studies Manager (apprenticeship)

Studies and costing of electrical connection work for individuals and professionals.

Ranked among the 14 finalists of a national competition (Victoires de l'Innovation) for software I took initiative to develop. This software was distributed in several ENEDIS agencies in France to help the employees to create their electrical studies files.

2023: Extension of Mitsuba 3, an open source spectral renderer coded in C++, to take fluorescent materials into account. Keywords: C++, CUDA, spectral rendering, optics.

2022: Expanding Malia Rendering Framework (an open source renderer) to multi-layered materials. Keywords: C++, real-time spectral rendering, CUDA, optics.

2022: Expanding BRDFExplorer (a Disney software for visualizing BRDFs) to BSDFExplorer (to observe BSDFs). Keywords: C++, Qt, OpenGL, GLSL, optics.

2021: Adding a plugin to Ossia-score, an open-source sequencer, to write electroacoustic sheet music. Repo: https://github.com/Pnixys/score-addon-acousmoscribe. Keywords: project management, C++, Qt, MVP pattern.

2020: IRC chat in Python. Repo: https://github.com/llachiver/IRC_python. Keywords: network, socket, file transfer.

2019: INRIA internship: Improving the appearance of wet materials. Details here. Ended in a chapter of a CNRS book. Keywords: Substance Designer, real-time rendering, GLSL, shading.

2019: Photo editing app on Android implementing advanced effects (Contrast-Limited Adaptative Histogram Equalization, convolutions, etc.). https://github.com/picachoc/pimp-android. Keywords: android, UX, Renderscript, image processing, Java.

2019: Strategy game with AIs coded in JavaFX

Games Portfolio

Here are the games we developed with my team, along with details about my contribution. All of them were made with Unity 2D!

Most of them were made for The Ludum Dare, a world-wide event which imposes 3 days for making the whole game: development, art and music.

🗓️Ludum Dare 58

Marble Trouble - A marble game where you build your collection to defeat bosses.

Dev. : Inventory system & shooting system, general scripting

Music :
- Win theme: funky celebration music

🗓️Ludum Dare 57

Leap of faith - You control a fallen angel with your mouse and have to avoid all the obstacles on the way until the final bullet-hell boss.

Dev. : Level design, scripting of the bullet-hell boss

Music :
- Sky theme: angelic drum and bass with organs and choir
- Boss theme: power metal with epic solos, Helloween-inspired

🗓️Ludum Dare 54

Worm out - Top-down shooter where some strange creatures have invaded the facility.

Music : main loop of horror ambient music (processed strings sounds and custom synthesizers patches).

🗓️Ludum Dare 55

Fried Away - Silly endless runner where you should avoid to get fried.

Dev. : player movements, random level generation with objects pooling.

Music : country/folk miniature for the cinematic intro, neurobass/bluegrass for the main game loop (feat. Anachrone).

🗓️Ludum Dare 49

Doctor Psycho - Ambulance driving game where the goal changes randomly from saving your patient to do the most damages possible in the city.

Dev. : level design, AIs for pedestrians and cars, cars and pedestrians generation with objects pooling.

Music : jazzy drum and bass which switches to a metal version when the driver gets mad.

🗓️Ludum Dare 48

Deep Down the Abyss- Evil Lovecraftian creatures want to beat your ass.

Music :
- Theme 1 : epic music mixing strings, a Chinese erhu for the mysticism and synthesizers for bass and textures
- Theme 2 : black metallish battle music with anvils, timpani and brass
