Ruixiang Cao

IEEE/RSJ IROS 2025 · First Author

Trains a monocular navigation model via self-supervision from uncalibrated, human-captured videos, yielding a generalist policy that guides various robots in unfamiliar environments.

ACM SIGGRAPH 2025 · Emerging Technologies Best in Show · Co-first Author

Transforms radiance-based volumetric representations (e.g. NeRF) into physically fabricable Volumetric Printing Primitives for high-fidelity full-color 3D printing. Recipient of the SIGGRAPH 2025 Emerging Technologies Best in Show Award — a first for a Chinese institution.

Kyoto University, Learning Machines · First Author

A Printable-Voxel framework that removes view-dependency and maps digital RGB into a physical CMYKWCl color space, directly outputting full-color voxel grids for photopolymer-jetting 3D printing.

ACM SIGGRAPH Asia 2022 · Co-author

Published at ACM SIGGRAPH Asia 2022 (ACM Transactions on Graphics). Presents a video-driven approach for building neural physically-based facial assets that fit production rendering pipelines, balancing editability and visual realism.

IEEE IROS 2022 · First Author

Published at IROS, a top-tier robotics conference. Proposes an omnidirectional wheel-leg dual-mode transformable mechanism.

Club Project · Real-time Video Light Wall · Jetson + Arduino

A wall of filament LEDs driven by Jetson Xavier NX and Arduino, rendering a live camera feed as a warm-toned light display.

Club Project · Stepper Motors Playing MIDI · Arduino

Parses MIDI with Python’s mido and drives stepper motors over serial so the motors “sing” by pitch and rhythm.

Course Project · Post-apocalyptic Survival Shooter · Unity

A self-made post-apocalyptic survival shooter with a building system, environment interaction, inventory, and original sound effects.

Lab Project · ShanghaiTech MARS Lab

Led, as the core student lead, the build of a spherical dome light-field 3D capture rig for facial geometry and material capture.

After Graduation Sparsee × Stratasys Joint Livestream · Guest Speaker

Official Stratasys livestream announcement: Sparsee and Stratasys go live on how 3DGS moves from screen to physical material, with Ruixiang Cao presenting the print3dgs.com platform and voxel-data preparation workflow.

After Graduation Industry Media Coverage · Livestream Announcement

NanjiXiong explains the 3DGS-to-print pipeline: Sparsee prepares 3DGS content via print3dgs.com, Stratasys fabricates it with PolyJet voxel printing, and the two announce a joint technical livestream.

After Graduation In-depth Founder Interview

A long-form founder interview tracing the path from light-field reconstruction to full-color UV 3D printing — turning a moment into a permanent memory.

After Graduation Co-first Author of the DreamPrinting Paper

Official SIST news: CAST won the conference Best Paper Award; DreamPrinting, co-first-authored by Ruixiang Cao, received the Emerging Technologies Best in Show Award — a first for a Chinese institution.
