Researcher

Cheng Sun

Cheng Sun is a research scientist at NVIDIA Research Taiwan, where his work covers 3D reconstruction and scene understanding. He coauthored HorizonNet, a panoramic room-layout model, and Direct Voxel Grid Optimization for radiance-field reconstruction with voxel grids. In 2025, he coauthored Sparse Voxels Rasterization and Play4D, spanning adaptive-voxel rendering and free-viewpoint video for virtual-reality and light-field displays. In 2026, he coauthored a real-time radiance-field renderer for light-field displays.

Timeline

  1. 2018–2023

    A PhD at Tsing Hua

    He earns a PhD from the Institute of Information Systems and Applications at National Tsing Hua University. His time there spans 2018 to 2023.

  2. 2019

    Room layouts from panoramas

    At CVPR 2019, he coauthors HorizonNet, which estimates room layout from a panoramic image using three one-dimensional vectors.

  3. 2022

    Voxel-grid radiance fields

    At CVPR 2022, he coauthors Direct Voxel Grid Optimization, a grid-based approach for rapid per-scene radiance-field reconstruction.

  4. 2025

    Rendering with sparse voxels

    At CVPR 2025, he coauthors Sparse Voxels Rasterization, which rasterizes adaptive sparse voxels to render radiance fields in real time.

  5. 2025

    Play4D streams free-viewpoint video

    At SIGGRAPH Asia 2025, he coauthors Play4D, a free-viewpoint video streaming pipeline for virtual-reality and light-field displays.

  6. 2026

    Real-time light-field rendering

    At HPG 2026, he coauthors a real-time renderer for radiance fields on light-field displays; it uses shared sweeping planes to compose many views in one pass.

  7. Since 2023

    Research scientist at NVIDIA

    He joins NVIDIA Research Taiwan as a research scientist in September 2023 and works in Taipei on 3D reconstruction and scene understanding.
