MASc Candidate in Computer Graphics @ ÉTS
Last updated
About
I am a MASc candidate in computer graphics at ÉTS under the supervision of Prof. Adrien Gruson and Prof. Eric Paquette.
I am interested in all things rendering! In particular:
- Production rendering
- Light transport algorithms
- High performance graphics
- Sampling
In my free time, I am currently working on my own Blender compatible production renderer.
Publications
Projects
A production-style Monte Carlo renderer written from scratch in C++20.
An interactive, real-time, physically-based simulation of a stone skipping on a water surface.
An interactive, real-time, in-browser visualization of Metropolis Light Transport.
A from-scratch rendering research playground for prototyping advanced rendering algorithms.
A differentiable volumetric path tracer using 3D Gaussians in a faithful radiative-transfer formulation.
Resume
Work Experience
- Added raytraced, relightable 3D Gaussian splats to the Arnold rendering core, on both CPU (SIMD) and GPU (OptiX); shipping in Arnold 7.5.2 and 3ds Max 2027.
- Derived novel splat-intersection methods, numerically stable and 2.6× faster than naive intersection, that outperformed competing production renderers.
Supervisor: Prof. Toshiya Hachisuka
- Developed the core statistical formulation behind a neural spatiotemporal denoiser for Monte Carlo rendering animations (second author, Eurographics 2026).
- Implemented a common-random-number animation integrator in Mitsuba to generate network inputs; cut inference time by >99.9% via vectorization and parallelization.
