Spectral Rendering Without a Spectral Renderer: Learned Spectral Codes for RGB Pipelines
Jiaqi Yu, Dar'ya Guarnera, Giuseppe Claudio Guarnera
Spectral rendering reproduces the wavelength-dependent appearance that RGB rendering cannot: metamerism, colour shifts under spectrally rich illumination, coloured glass, metallic…
PBR-Inspired Controllable Diffusion for Image Generation
Bowen Xue, Giuseppe Claudio Guarnera, Shuang Zhao +1
Despite recent advances in text-to-image generation, controlling geometric layout and PBR material properties in synthesized scenes remains challenging. We present a pipeline that…
ReflectanceFusion: Diffusion-based text to SVBRDF Generation
Bowen Xue, Giuseppe Claudio Guarnera, Shuang Zhao +1
We introduce Reflectance Diffusion, a new neural text-to-texture model capable of generating high-fidelity SVBRDF maps from textual descriptions. Our method leverages a tandem neur…
