Ray Tracing with bouncing balls

A little shadertoy, with dynamics to show the beauty of rendering.

Angry trunk!

A mobile game made using COCOS2DX.

Cyber Creed

A 3D stealth game under cyberpunk world using UE4.

AliCloth Rendering project

This is my undergraduate graduation project, which was used in a clothing rendering project at Alibaba.

Volumetric Path Tracing

Implement Volumetric Path Tracing for both homogeneous and heterogeneous volumes.

Disney Principled BSDF

Implement Disney Principled BSDF in a Monte Carlo path tracer.

Discrete Differential Geometry course project

Implement Geodesic Distance using Heat Equation and Surface Laplacian and cross field on a bunny, as well as Spectral Conformal Flattening, like texture mapping.

My single scatter NeRF

Attempted to implement Single Scatter NeRF. I explored various network structures and representations of phase functions.

Neural BRDF for Inverse Rendering

We try to use neural BRDF for inverse rendering. I explored various network structures for neural BRDF.

TensoRF with the SGGX Microflake Distribution

I implemented the NeMF using TensorRF as acceleration.

CSE 274 instructed by Ravi course project

My final project is to implement Stereo Magnification: Learning View Synthesis using Multiplane Images.

Parallel Computation course projects

There were three assignments in the Parallel Computation course, each implementing matrix multiplication on different platforms: CPU, GPU, and MPI-distributed tasks.

My first paper! A a real-world dataset designed for inverse rendering task!

HotSpot: Screened Poisson Equation for Signed Distance Function Optimization Permalink

Published in Arxiv, 2024

Zimo Wang, Cheng Wang, Taiki Yoshino, Sirui Tao, Ziyang Fu, Tzu-Mao Li

BSDF importance sampling using a diffusion model Permalink

Published in SIGGRAPH Asia 2024 (conference track), 2024

Ziyang Fu, Yash Belhe, Haolin Lu, Liwen Wu, Bing Xu, Tzu-Mao Li

My representative paper (I like to do this type of research, combining with some math, interesting theory and (optimized) coding).

We find that low-dimensional, deterministic diffusion models are useful for BSDF importance sampling!
