Misc

Asuna: Vulkan-based Path Tracer

Asuna is a renderer base on vulkan ray tracing pipeline with NVIDIA card. It supports both rendering with gui and headless rendering. It implements multiple importance Monte Carlo sampling and fundamental materials.  [code]

Circuit-level Differentiable Hardware for Visual Computing

Used a hardware-level(FPGA) diffrentiable device to capture geometry and appearance of real-world objects. We leverage a Basler racer line scanner camera to capture and optimize the physical properties of the LED lighting module, which is controled by a Zynq xilinx FPGA.

Simplay: implemented physically-based animation tools and algorithms

Implemented dynamics of Rigid body/cloth/elastic body/shallow wave/character animation. Stable fluid/PIC/FLIP/APIC/2-way coupling MPM were implemented. SIGGRAPH Paper Fast Simulation of Mass-Spring Systems and Position-Based Surface Tension Flow were also implenmented.  [GAMES103/201,cloth,pbstf]
