Jorge Condor
PhD Student
I am a PhD Student on Computer Graphics at IDSIA-USI (Lugano, Switzerland) under the supervision of Piotr Didyk. My research focuses on leveraging inverse graphics to improve applications in vision, real-time rendering and fabrication. During my PhD I had the opportunity to intern at Meta Reality Labs and work alongside the talented Monaco Rendering Team, working on accelerating physically-based volume rendering for photorealistic avatars, under the supervision of Christophe Hery and Adrián Jarabo. I'm also an avid photographer and I love trekking in my spare time.

Publications
Don't Splat your Gaussians: Volumetric Ray-Traced Primitives for Modeling and Rendering Scattering and Emissive Media
ArXiv [May'24]
Banking on the popularity of rasterized 3D Gaussian Splatting methods, we formalize the ray-tracing of volumes composed of kernel mixture models (Gaussian or otherwise). Our physically-based, path-traced formulation allows us to render and optimize both scattering and emissive volumes, as well as radiance fields, in an extremely efficient and compact manner. We also introduce the Epanechnikov kernel as an efficient alternative for the Gaussian kernel in radiance field rendering, and showcase the advantages of a ray-traced framework, while maintaining real-time performance.
Gloss-aware Color Correction for 3D Printing
Proceedings of SIGGRAPH [SIGG'23]
We measure, model and correct perceived color shifts in 3D printed objects with different levels of gloss. To formulate the correction we conduct novel perceptual experiments and propose an optimization procedure solved using differentiable rendering.
A Learned Radiance-Field Representation for Complex Luminaires
Eurographics Symposium on Rendering [EGSR'22]
An efficient method for rendering complex luminaires using a high quality octree-based representation of the luminaire emission modelled through Neural Radiance Fields, achieving up to x100 speedups over explicit modelling
A Generative Framework for Image-based Editing of Material Appearance using Perceptual Attributes
Computer Graphics Forum, presented at Eurographics 2022 [CGF'21]
An image-based editing method that allows to modify the material appearance of an object by increasing or decreasing high-level perceptual attributes, using a single image as input.
Normal Map Estimator from Single RGB Images of Objects in the Wild
Jornada Jóvenes Investigadores I3A 2021, Poster Session [JJI-I3A'21]
We apply recent advancements in generative neural networks and an untapped dataset to the problem of volume estimation from a single RGB input and train a model that performs the task efficiently, ready to deploy in other vision and computer graphics pipelines
