DISTWAR: Fast Differentiable Rendering on Raster-based Rendering Pipelines

no code implementations1 Dec 2023 Sankeerth Durvasula, Adrian Zhao, Fan Chen, Ruofan Liang, Pawan Kumar Sanjaya, Nandita Vijaykumar

In this work, we observe that the gradient computation phase during training is a significant bottleneck on GPUs due to the large number of atomic operations that need to be processed.

ENVIDR: Implicit Differentiable Renderer with Neural Environment Lighting

1 code implementation ICCV 2023 Ruofan Liang, Huiting Chen, Chunlin Li, Fan Chen, Selvakumar Panneer, Nandita Vijaykumar

In this work, we introduce ENVIDR, a rendering and modeling framework for high-quality rendering and reconstruction of surfaces with challenging specular reflections.

Operator Fusion in XLA: Analysis and Evaluation

no code implementations30 Jan 2023 Daniel Snider, Ruofan Liang

Machine learning (ML) compilers are an active area of research because they offer the potential to automatically speedup tensor programs.

SPIDR: SDF-based Neural Point Fields for Illumination and Deformation

no code implementations15 Oct 2022 Ruofan Liang, Jiahao Zhang, Haoda Li, Chen Yang, Yushi Guan, Nandita Vijaykumar

To enable more accurate illumination updates after deformation, we use the shadow mapping technique to approximate the light visibility updates caused by geometry editing.
