About Me

Hi! I'm Cheng Wang, a Computer Vision Research Engineer at Dandy. I have developed a strong passion for Visual Computing, particularly interested in inverse problems. I recently earned my Master's degree in Computer Science from UC San Diego, advised by Prof. Tzu-Mao Li. Before that, I received my Bachelor's degree in Computer Science and Technology at Chu Kochen College of Zhejiang University, advised by Prof. Rui Wang.

I was also a Software Engineer Intern at Electronic Arts and a Rendering Engine Engineer Intern at Rays Engine. Feel free to take a look at my Resume.

Projects

Volumetric Path Tracer

A volumetric path tracer that can handle multiple chromatic heterogeneous volumes with absorption and multiple-scattering, with both phase function sampling and next event estimation, based on an educational physically-based renderer, lajolla.

Autonomous Vehicle Motion Forecasting

A course project using deep learning models to forecast autonomous vehicle motion, predicting object positions three seconds ahead.

Implementation of Tensorial Radiance Field (TensoRF) with PyTorch

TensoRF represents a radiance field by matrix-vector and vector-vector combinations of tensors. Compared to MLP based NeRF, it is more efficient while preserving comparable quality without customized CUDA implementation.

Real-Time Texture-Space Subsurface Scattering

An efficient method to compute convolution of radiance map and weight kernel in texture space. By pre-calculating weight kernels with Burley's normalized diffusion profile and applying wavelet transformation, the method significantly reduced time complexity of convolution.

Awarded the Outstanding Graduation Thesis of Zhejiang University Undergraduates in 2022.

Tiled Forward Shading

An implementation of tiled forward rendering and tiled deferred rendering, with optimized light culling pass by using multiple frustum dividing and light-frustum intersection strategies.

Cyber Creed

2021

A 3D computer game resembling Assassin's Creed with Unreal Engine 4.

Medical Appointment System

A course project implementing a hospital website with Vue.js and Java, whose main functions including information viewing, registration appointment, online consultation, video diagnosis, online forum, etc.

Petiu: Pet farewell service system

An IOS App "Petiu" written in SwiftUI.

Awarded Third Prize in the China Collegiate Computing Contest -- Mobile Application Innovation Contest held by Apple Inc. and Zhejiang University in 2021.
